Which soil is best for making bricks?
The best-suited soil for the manufacturing of bricks will be silted clay or weathered clay as this soil has sufficient cohesion and little silt content will aid in the strength. Weathered soil has an adequate amount of moisture. Weathering provides proper texture and plasticity to clay to ensure the softening of clay.
