Secondly, the steel rods can be inserted or mortar poured into them to increase the building’s strength and stability. Thirdly, cost savings as cement and sand are of minimum used for constructing the wall and less labour intensive and more time saving.

The block is ready for use after water curing for 7 days. the block will have compressive strength of 20 T. The length of each block is exactly double its width, in order to achieve accurate alighnment of bricks placed at right angles.
