Thought BankSuperstition and Belief (Science Behind our Customs and Ceremonies ) by Er.S.Ramanathan, F.I.E , Structural Consultant, Chennai: continued from last month news letterHeat therapy - 1! It is most commonly used for rehabilitation purposes. ! The therapeutic effects of heat include increasing the extensibility of collagen tissues! Decreases joint stiffness; reducing pain; relieving muscle spasms; reducing inflammation, edema, and aids in the post acute phase of healing; and increasing blood flow. The increased blood flow to the affected area provides proteins, nutrients, and oxygen for better healing.Heat therapy dilates the blood vessels of the muscles surrounding the lumbar spine
Why do we test concrete compressive strength after 28 days?The table below shows the compressive strength gained by concrete after 1, 3, 7, 14 and 28 days with respect to the grade of concrete we use.

From above table, we see that, concrete gains 16 percent strength in one day, 40 percent in 3 days, 65% in 7 days, 90%
in 14 days and 99% strength in 28 days. Thus, it is clear that concrete gains its strength rapidly in the initial days after
casting, i.e. 90% in only 14 days. When, its strength have reached 99% in 28 days, still concrete continues to gain
strength after that period, but that rate of gain in compressive strength is very less compared to that in 28 days. After 14 days of casting concrete, concrete gains only 9% in next 14 days. So, rate of gain of strength decreases. We
have no clear idea upto when the concrete gains the strength, 1 year or 2 year, but it is assumed that concrete may
gain its final strength after 1 year. So, since the concrete strength is 99% at 28 days, its almost close to its final strength,
thus we rely upon the results of compressive strength test after 28 days and use this strength as the base for our
design and evaluation.Though there are also some rapid method of testing concrete compressive strength which
gives relation between rapid test methods and 28 day strength. This rapid test is done where time is limited for
construction and strength of structural member must be known to carry out further construction work.As per IS 456 and BS CP 114 concrete gains 120 % -124 % strength in one year. This is a pretty long time to test
concrete and commence the project. Hence the principle of the ' Law of Averages' ( LOA) is adopted. The LOA states:
“the principle that, in the long run, probability as naively conceived will operate and influence any one occurrence.”The LOA was formalized as a law of large numbers ( LLN ) and was first proved by Jacob Bernoulli. It took him
over 20 years to develop a sufficiently rigorous mathematical proof which was published in his Ars Conjectandi (The
Art of Conjecturing) in 1713. He named this his "Golden Theorem" but it became generally known as "Bernoulli's
Theorem". This should not be confused with Bernoulli's principle, named after Jacob Bernoulli's nephew Daniel
Bernoulli., who gave the most important principle in
Fluid Dynamics.Thus by Statistical principle the 28 day compressive strength of Concrete is relied upon by the The Art of
Conjecturing , propounded by Jacob Bernoulli.

Guest of the day and delivered the Energy Conservation Day address. The meeting was presided over by
Mr.K.Vijayakumar, FIE., Chairman, Madurai Local Centre. Mr.J.Samuel ,MIE., Hon. Secretary and Mr.R.Narayanasamy,
MIE., Joint Hon. Secretary were also on the dais. The Chairman, Mr.K.Vijayakumar delivered the welcome address.
Then announced the demise of the Tamil Nadu Chief Minister Miss.J.Jayalalitha and requested the participants of the
meeting to stand up and observe one minute silence and pray for the great soul to rest in peace. Then the Hon.
Secretary introduced the Chief Guest to the audience. Mr.V.C.Gandhi, FIE., Past Chairman honoured the Chief Guest
with a shawl.The chief Guest in his speech said that World Energy Conservation Day is celebrated on 14th December globally
to highlight the importance of energy consumption and its use in our day-to-day life, its scarcity and its impact on
sustainability of global eco systems. He said that it focuses our concentration on significant issues facing the future of
mankind with respect to energy. It is a day for building up awareness regarding need for energy conservation, Energy
efficiency and Frugality in energy use. Fossil fuels, Crude oil, Coal, natural gas, etc generate sufficient energy for the
use in daily life. But day-by-day the demand is increasing and creates the fear of reducing or diminishing the natural
resources. He said the Source of Energy currently in the world are Fossil Fuel- 74.3 %,Bimas15.0%,Hydro Power- 5.5%
and Nuclear Power- 5.2%. Energy conservation is the only way which helps in replacing the non-renewable resources
of energy with the renewable energy. Some of the important goals of the day are: A) It is celebrated to send the
message of importance of conserving energy in the every walk of life among people. B)Promoting the way of process
of energy conservation by organizing a lot of events such as discussions, conferences, debates, workshops,
competitions, etc all through the country. C)Promote people for less energy usage by neglecting the excessive and
wasteful uses. And D) Encourage people for efficient energy use in order to decrease the energy consumption and
prevent the energy loss. The Energy Conservation Act was enacted in 2001 which facilitated the appointment of
Energy Managers and Energy Auditors for Industries for strict observation of Energy conservation. Then Bureau of
Energy Efficiency has communicated various energy saving methods, started certifying energy efficient equipments
with star ratings.He also introduced Mr.K.C.Agilan, Plant Manager, JK Fenner near Nilakkottai who worked with him at Madurai
Fenner India Ltd., and undertook all the Energy saving methods. He said that saving energy also helps in reducing the
pollution level. Energy production and its usage account to large proportion of air pollution and more than 83 % of
greenhouse gas emissions.Then he explained the approach to be adopted for Energy conversion in Industry: 1) Identified the Energy
Manager.2) II level staff for daily monitoring and coordinate ENCON implementation.3) Identify Projects internally.4) Identify the Project externally (CII-Energy Audit) .5 0Conduct detailed financial analysis. 6) List and priorities

Projects financially and functitonally.7) Obtain approval from top management. 8) Implement and monitor ENCON
Projects.He explained various methods adopted in his industry case by case with cost of energy saved and along with
payback period for the investment. He explained about a design modification in the conventional type hydraulic
power packs, where there are two pumps connected to the motor common shaft. One low pressure, high capacity
pump operates for initial fill up. The high pressure pump(plunger pump-typical) runs for pressure build up. Whenever
the system reaches its desired pressure setting, the recirculation line (relief line) opens and maintains a constant
pressure in the header. Therefore the pump and motor continuously runs in full speed condition, irrespective of
utilization. Hence the energy consumption levels remain constant irrespective of condition of operation. When the
hydraulic press is stationery, (there is no movement), the hydraulic Pump is required only to maintain the pressure (to
hold/perform the job). As hydraulic oil is incompressible, the entire volumetric capacity of high pressure pump has to
be relieved through the relief valve or recirculation line. The entire power consumption of the hydraulic pump is
wasted during the time. In this context, a variable speed system (VFD) installation facilities to reduce / increase the
speed of the hydraulic pump to keep the header pressure constant. This minimizes/ avoids recirculation and saves
energy. He explained the task wise savings achieved as below:Task 1 :To Install Variable Frequency Drive In Power Pack - 12 Units. Action Taken : Installed 3 Units Of V.F.D In
April 2001.Saving Units - 56 Units Per Day. Rs.200 .00 Per Day, Rs.60,000.00 per Annum Payback Period : Less Than

3D printing technology is the new scientific development in the fields of Mechanical Engineering, Medicine,
Sports and toys world etc. The same technology has been extended to Civil Engineering as 3D Concrete Printing in
which houses can be constructed within 24 hours. 3D concrete printing technology is an innovative construction
method that promises to be highly advantageous in the construction field in terms of optimizing construction time,
cost, design flexibility, error reduction, and environmental aspects. 3D Concrete printing is a new construction method
that has the capability of fabricating a redesigned building element in 2D layers on top of each other, the repetition of
which completes a 3D model. Concrete is poured out or extruded through a nozzle to build structural components
layer-by-layer without the use of formwork or any subsequent vibration.
3D concrete printing is a promising tool in the construction industry. With a mix that satisfies various design and
operational constraints, houses can be built using this innovative technique without the use of formwork. The printer
moves in three directions to construct a wall, and eventually other kinds of structures. The application of the printing
prototype is very effective, at least for small-scale structures. Such a technique can easily be used wherein need of a
suitable, low-cost and fast building construction method. 3D concrete printing offers savings in terms of long-term
cost, time, labor and complexity, which are very important current factors in the construction industry. As the method
is not limited by any type of formwork or manual labor, designers will have much more design flexibility in that scope.

Lifting of Buildings is the process of separating a structure from its foundation and temporarily
raising it with hydraulic or screw jacks. Lifting of buildings may also be a part of a renovation to build a
foundation under an existing building or make a structure larger by building a new floor level creating
a two storey structure. Once a building is raised and supported on jacks, a new foundation can be
constructed beneath it. After Chennai flood in Dec 2015, large number of buildings are being raised
to avoid future flooding.
Necessity for lifting of buildings, methodology and procedure to be adopted were deliberated
with the help of videos and power point presentation. Many case studies including lifting of Railway
Over Bridge(ROB) at Kozhikode were discussed during the presentation.
Lifting of buildings technologies are cheaper, very effective and saves lakhs of rupees and
valuable time. When your house is below the road level, it can be easily lifted and shifted without any
damage and raising their level in one go with the help of Jack. It is essential to manage all equipment
operating systems successfully to complete the process of lifting. The building lifting task can be
completed by a team of certified professionals who know, how to use the equipment and those have
experience in handling such a project. Lifting of building is an intensive process performed for a
variety of structural, safety and aesthetic purposes. Dr. K. Chockalingam, presented the memento to
the chief guest and the Er. R. Narayanasamy, Joint Hon. Secretary delivered vote of thanks. The
meeting was adjourned.

Safe and inexpensive hydrogen production as a future energy sourceDate: December 20, 2016Source: Osaka UniversitySummary:
Researchers have developed an efficient "green" hydrogen production system that operates at room
temperature in air.a) Gold nanoparticle catalyst (Au/HAP-NC), b) Images of gold nanoparticles (black dot in red circle)

Electron Microscope.Credit: Image courtesy of Osaka UniversityHydrogen gas is a promising alternative energy source to overcome our reliance on carbon-based fuels,
and has the benefit of producing only water when it is reacted with oxygen. However, hydrogen is highly
reactive and flammable, so it requires careful handling and storage. Typical hydrogen storage materials are
limited by factors like water sensitivity, risk of explosion, difficulty of control of hydrogen-generation.
Hydrogen gas can be produced efficiently from organosilanes, some of which are suitably air-stable, non-
toxic, and cheap. Catalysts that can efficiently produce hydrogen from organosilanes are therefore desired
with the ultimate goal of realizing safe, inexpensive hydrogen production in high yield. Ideally, the catalyst
should also operate at room temperature under aerobic conditions without the need for additional energy
input.A research team led by Kiyotomi Kaneda and Takato Mitsudome at Osaka University have now
developed a catalyst that realizes efficient environmentally friendly hydrogen production from
organosilanes. The catalyst is composed of gold nanoparticles with a diameter of around 2 nm supported on
hydroxyapatite. The catalyst was synthesized from chloroauric acid using glutathione as a capping agent to
prevent nanoparticle aggregation, resulting the formation of small size of gold nanoparticles. Glutathione-
capped gold nanoparticles were then adsorbed on hydroxyapatite and glutathione was removed by
subsequent calcination.The team then added the nanoparticle catalyst to solutions of different organosilanes to measure its
ability to induce hydrogen production. The nanoparticle catalyst displayed the highest turnover frequency
and number attained to date for hydrogen production catalysts from organosilanes. For example, the
nanoparticle catalyst converted 99% of dimethylphenylsilane to the corresponding silanol in just 9 min at
room temperature, releasing an equimolar amount of hydrogen gas at the same time. Importantly, the
catalyst was recyclable without loss of activity. On/off switching of hydrogen production was achieved using
the nanoparticle catalyst because it could be easily separated from its organosilane substrate by filtration.
The activity of the catalyst increased as the nanoparticle size decreased.A prototype portable hydrogen fuel cell containing the nanoparticle catalyst and an organosilane
substrate was fabricated. The fuel cell generated power in air at room temperature and could be switched on
and off as desired. Images of the catalyst after use in the fuel cell resembled those of the unused catalyst,
indicating that the hydroxyapatite-supported nanoparticle catalyst readily resisted aggregation.Generation of hydrogen from inexpensive organosilane substrates under ambient conditions without
additional energy input represents an exciting advance towards the goal of using hydrogen as a green energy
source.
