Abstract

The invention relates to high activity cement mineral forming accelerating agent applied to produce new type dry method cement. It is made up of seed crystal activating agent and high calcium carrier, and their proportioning by weight respectively are from one portion to three portion, and from eight portion to twenty four portion. The constituent and weight content of the seed crystal activating agent is from forty percent to eighty percent of the slag, the mineralizing agent is from twenty percent to sixty percent. The main effects of the accelerating agent supplied by the invention are that it obviously appear the seed crystal and mineralizing action, can greatly improve the raw material inflammability, reduce the fire temperature, broaden the fire range, increase the C3S content and activity of the clinker, so that increase the output and quality, as well as save resource and energy source, reduce the environment loading, and possess better economic and social benefit.

Description

technical field

[0001] The invention relates to the field of building materials, in particular to a highly active cement mineral formation accelerator, which is suitable for the production of new dry process cement. Background technique

[0002] Additives that accelerate or improve the formation of cement minerals, such as cement mineralizers, raw meal activators, etc., have been studied a lot at home and abroad, and there are a lot of literature. The main technical contents in these documents are:

[0003] 1. Mineralizer formed by cement minerals: Cement clinker firing is a solid-liquid phase reaction process with slow reaction speed and high temperature, and CaCO 3 Decomposition and liquid phase formation require a large amount of energy and affect clinker yield and quality. The introduction of mineralizer can accelerate the generation of liquid phase and promote C 3 The formation of S can improve the burnability of raw meal, increase the output and quality of clinker, ...
