HIGH ACTIVITY CEMENT CLINKER, HIGH ACTIVITY CEMENT, AND EARLY STRENGTH CEMENT COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide high activity cement clinker capable of responding even to use of industrial waste as part a cement firing raw material and serving as a base material of an early strength cement-based solidifying material or early strength cement having high versatility, and high activity cement obtained by adding a proper quantity of gypsum to the high activity cement clinker.;SOLUTION: The high activity cement clinker serving as a base material of an early strength cement-based solidifying material or early strength cement has a mineral composition satisfying C₃S70% and C₂S5% as calculated values by the Bogue expression, and satisfies L.S.D.1. The amount of free lime in the cement clinker is 0.5-7.5 wt.%.;COPYRIGHT: (C)2012,JPO&INPIT
