MORTAR AND CONCRETE HOLLOW BLOCKS
The document discusses mortar and concrete hollow blocks. Mortar is made from a mixture of fine aggregate, water, and cement that is used to bind bricks or stones. Concrete hollow blocks are large rectangular bricks made primarily from cement, sand, and gravel. They have hollow cores which make them lighter and more insulating than solid blocks. The document outlines the production process and advantages of using concrete hollow blocks for construction.

Proper curing increase compressive strength of the blocks. • Low Maintenance • Fire Resistant • Provide thermal and sound insulation • Economical • Environment Friendly
- 10. SSttrruuccttuurraall AAddvvaannttaaggeess •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
- 11. CCoonnssttrruuccttiioonnaall AAddvvaannttaaggeess •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
- 12. 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.
