New research set out to improve the engineering quality of clay using waste materials and a secret binder ingredient. Clay is a natural material composed primarily of fine-grain minerals. It consists of tiny particles that have plastic and adhesive properties. Clay also possesses small voids and pores, so it’s capable of retaining water. In this condition, it tends to expand and shrink, which can lead to settlement.
