CEMENT PRODUCT AND METHOD OF PRODUCING THE SAME AND COMPOSITION FOR PRODUCING CEMENT PRODUCT AS WELL AS MASS CONCRETE AND METHOD OF PRODUCING THE SAME TOGETHER WITH CEMENT FOR PRODUCING MASS CONCRET

摘要

A composition for producing a sphered cement product, which comprises a mixture of a sphered cement, aggregate and water, the sphered cement consisting essentially of cement clinker fine particles the outer peripheral surface of which is sphered by grinding and/or fusion, at least 60wt% of the particles having a diameter of from 3.9 to 30.0 .mu.m. Also disclosed are a sphered cement product obtained from this composition and a method of producing a sphered cement product by curing the above-described mixture.
