SFRC Flooring and Nano Silica Densification : The Cutting Edge Green Technology

SuStainable and Green ConStruCtion

LTFS is a name that has become synonymous with quality

flooring solutions. We bring in state-of-the-art machinery

S 15 R laser screed machine with telescopic boom for

the purpose of laying the floors which has many advantages in

comparison to Conventional VDF. Flooring.

We prefer Steel fibre reinforced concrete as an alternate to

traditional mesh reinforcement. Glued Steel Fibre Reinforced

Concrete (SFRC)-provides you with a time saving and cost

efficient solution for flooring. Being multi-dimensional

reinforcement it offers following advantages:-

– Optimal Load Bearing,

– Optimal Crack Control,

– High Fatigue Resistance,

– High Impact Resistance,

– Easier to Maintain,

– Longer Lifespan,

– Optimized Thickness,

– Timesaving Construction,

– Better Performance,

– The Ductile Steel Fibre Floor With Stands

Moderate Deformations, Minimizes Curling of

Concrete Slab;

– Easier and More Accurate Installation of Super

Flat Floor.

Steel fibres are

commonly used in

concrete to provide

structural (load-

bearing) capacity

and for the control

of shrinkage-induced

cracking. Steel fibres

for reinforcing concrete

are manufactured from

cold-drawn wire and are

used in grade or ground supported floors. Normally the preferred

length is 60 mm, with aspect ratios of 80 (ratio of length to

nominal diameter). In order to gain pull-out resistance, fibres

have hooked end profile.

Use of Steel Fibres in industrial and warehouse flooring

reduces energy consumption by 16% (Approx.) per sq m in

comparison with steel bar / mesh reinforcement. Also, steel fibres

act as environment friendly concrete reinforcement designed

to offer an easy to use alternative for traditional steel mesh and

bar reinforcement. Depending on the finished product type,

different top wire rod sources are applied. On the overall Steel

Fibre Production volume, manufactures can state the percentage

of recycled steel used in their end product which may be around

20%.

Technology from Lythic USA for Densification & Dust-proofing,

creating “The HardWear FloorTM” for existing and newly

trowelled green concrete floors. Until recently, all densifiers used

alkali-metal compounds called “silicates” – such as sodium silicate,

potassium silicate, or lithium silicate. Silicates are old technology.

They have many drawbacks, which are overcome by a new type

of densifier chemistry, colloidal silica Nano Technology.

LYTHIC Colloidal Silica Nano Technology: New Technology for Better Concrete

Reactive Colloidal Silica – nano-sized particles in an acqueous

suspension – are the heart of Lythic advanced concrete treatment

system. Reactive Colloidal Silica is 99.5% pure

silica suspended in an ultra-low surface tension

liquid. The nanometer particles in their low-

viscosity suspension penetrate quickly, deeply, and

cleanly into concrete. Reactive Colloidal Silica also

bonds to itself, a property not found in any silicate

densifier. They react very efficiently with lime in

concrete, making them far more reactive than

conventional silicate densifiers. These reactions

form cementitious compounds in the concrete’s

pores that harden and densify the surface.

– Creates a Hard, Durable Floor

– Low Cost and Easy to Maintain

– “Green” Flooring

Lythic™ Densifier is a blend of inorganic polymer materials

that penetrates slab concrete to increase surface density and

hardness. Utilizing a proprietary and “green” manufacturing

process, Lythic™ Densifier’s unique formulation of uniform,

concentrated, Nano sized particles, suspended in an ultra low

surface tension liquid, penetrates deeply into concrete surfaces

bonding with the cement components of the slab. Lythic™

Densifier makes an extremely hard, dense floor surface that has

increased wear resistance to foot and fork lift traffic. It is water

based and environmentally friendly and is VOC compliant in all

states.

With experience of laying more than 1 Million M2 of floor

in last 4 years, we are here to deliver floors as per International

standards.

Old Technology: Silicate-based Densifiers

New Technology: Lythic Colloidal Silica

Highly caustic with 11 pH or greater

9 pH, a thousand times safer

High viscosity requires scrubbing to break surface tension, adding to labour cost

Low viscosity and simple spray-on application for quick penetration

Slow reacting, can require overnight dwell time

Reacts within minutes. Does not delay project

Alkaline residues require additional labour to remove and treatment as hazardous waste

No alkaline surface residue. No disposal costs

Surface must be rinsed to remove residue as water damage to building and finishes is possible

No rinsing required

Potential for difficult to remove surface whiting

No potential for whiting

Contains water soluble compounds that may be left in the slab and cause problems

Does NOT contribute to alkali-silica- reaction (ASR) which can cause swelling and cracking

Inconsistent and variable sized particles

Consistent 5 nanometer -sized particles
