Abstract
The mix is made of sandy soil, with ordinary Portland cement added in a proportion that depends on the soil; using a higher-grade cement helps raise the compressive strength significantly. Adding iron oxide improves compressive strength and lowers water absorption, while a non-coloring option is to add a small amount of natural glue to the mixing water, which also increases strength. During curing, the bricks should remain in place and not be moved. After curing, drying should be gradual, with the bricks protected from sun and wind and kept covered for a week, as this controlled drying further increases strength. Finally, walls built with the hollow interlocking bricks produced using this mix and curing approach should be coated with a transparent, water-based acrylic paint to reduce water absorption.
