Properties of Concretes with Admixture of Natural Zeolite

Article Preview

Abstract:

Natural zeolite is one of the raw materials whose application can reduce the content of cement in concrete. The reasons for the constant reduction of the amount of cement are not only its economical demands but also a strain on the environment. The paper describes basic characteristics of concretes with increasing substitution of cement with zeolite. The designed concretes with natural zeolite are being compared with a reference concrete without zeolite.
