摘要：
It is an object of the invention to provide a cement admixture that can form concrete having a sufficient self-healing capability and satisfactorily maintaining its self-healing capability for prolonged periods. The cement admixture of the invention contains an expanding material and an alumina-silicate with swelling properties. The cement admixture is combined with cement to form a cement composition. The cement composition is mixed with water and an aggregate to provide concrete with an excellent self-healing capability.
