AN EXPERIMENTAL STUDY ON IMPROVISATION OF CEMENT CONCRETE BY USING CHALCEDONY

Concrete is one of the widely used construction materials for structures .Cement concrete is an artificial stone produced by hardening mixture of cement, sand, stone chips and water. Since cement concrete is very good in compression but weak in tension, steel reinforcement are to be provided in tension zone. The low tensile strength and brittle character of concrete have been bypassed. The chalcedony is a rock which is obtained from the sedimentary type of rocks. The chalcedony is available in plenty in all the mountains. The chalcedony is made to a powder form and it is replaced to cement and experimental investigation is carried out. The replacement of cement by chalcedony has more strength than the ordinary conventional concrete.
