Hollow & Solid Blocks
They are prepared as solid blocks from cement, water and materials like ground sand, pulverized fly ash together with additives to aerate and stabilize the air bubbles.
The final result is a mixture of thick liquid which is then poured into steel moulds to form large cakes. Aftear some time, the mixture sets and ready to cut into a serious of individual blocks of required size using taut steel wires.
Hollow blocks are specially made for loadbearing walls, which are useful in reducing a dead load of masonry in buildings. Blocks can also be with cement and sand called cement-sand blocks or with cement and soil called soil-cement blocks which are of low strength and use for low-cost construction.
