ABSTRACT:
Utilizing exhaust materials from various plants and industrial wastes containing CaO, Al.sub.2 O.sub.3, SiO.sub.2 and Fe.sub.2 O.sub.3 as major components, inexpensive ground-strengthening/soil-improving material is obtained by blending thereinto clay minerals and sintering the resultant mixture. A high unconfined compressive strength is conferred upon the ground-strengthening/soil-improving material upon the addition of alumina.
