Q. How strong is laterite stone when compressed?

The mixture of 68% laterite stone waste 8% cement and 20% processed fly ash resulted in the strongest block with a compressive strength of 13.6 N/mm2. The block using 81% laterite stone waste 16% cement and 3% rice husk ash had the highest hardness index of 14.3. Bricks constructed from laterite with 45% sand and 5% cement achieved a compressive strength of 1.80 N/mm2 which is higher than the required minimum strength value of 1.65 N/mm2. When compared to concrete blocks bricks constructed from 45% sand and 5% cement saved builders in the city of Makurdi between 30% and 47% per square meter while burned clay bricks saved builders 19% per square meter.
