MORTAR
A fine aggregate and water mixed together in suitable proportions , they form an easily workable paste that use for binding materials

FUNCTION OF MORTARTo bind together the bricks or stones
properly so as to provide strength to the structure.
To provide a weather resisting
To fill up empty joints in brick and stone masonry.

Dry sand and cement in wheelbarrow
Begin to mix sand and cement
Mix to evenly distribute cement
The dry mix should be all one colour
Add water and plasticiser Mix to required consistency

CONCRETE HOLLOW BLOCKS
Is a large rectangular brick used in construction.
Portland cement and aggregate, usually sand and fine gravel for high-density blocks.

DESCRIPTION
• Have one or more hollow cores.
• In general, a hollow-core concrete block is
more than 50 % solid.
• Standard hollow concrete blocks come in ful l
and half sizes.
• Full-size blocks are rectangular and have two
cores.
• Half size blocks are cubical and have one
core.

ADVANTAGES OF HOLLOW ADVANTAGES OF HOLLOW CONCRETE BLOCKS. CONCRETE BLOCKS.
• Highly Durable: The good concrete compacted by high pressure and vibration gives substantial strength to the block. Proper curing increase compressive strength of the blocks.
• Low Maintenance
• Fire Resistant
• Provide thermal and sound insulation
• Economical
• Environment Friendly

Structural Advantages Structural Advantages
• Reducing the vulnerability (exposed to damage) of disastrous damage to the structure/building, during the natural hazards.
• Provide and offer better resistance under dynamic loading

Constructional Advantages Constructional Advantages
• No additional formwork or any special construction machinery is required for reinforcing the hollow block masonry.
• Only semi-skilled labor is required for this type of construction.
• It is a faster and easier construction system, when compared to the other conventional construction systems.
• It is also found to be a cost-effective disaster resistant construction system

Architectural and Other Advantages
• This construction system provides better acoustic and thermal insulation for the building.
• Faster construction: - Easy to work with bigger in size.
• Recommended for earth quake resistance.
• Less water absorption:- Approx. 3 to 4%
• Environmental Eco-Friendly
• This system is durable and maintenance free.
• No leaching: - Reduction in maintenance.
