Novel cement grinding aid

Abstract

A new cement grinding aid, which is made of the following raw materials in parts by weight: 4-7 parts of gypsum, 3-5 parts of sodium fluorosilicate, 2-6 parts of citric acid, 15-18 parts of stearic acid, fluorine 0.2-0.6 parts of sodium chloride, 2-4 parts of polyacrylamide, 3-6 parts of sodium silicate, 1.2-2.2 parts of preservative, 4-5 parts of accelerator, 8-16 parts of silica fume, 1.2 parts of organic early strength agent ‑2.5 parts, 1.8‑3.2 parts of phenyl salicylate, 1.2‑3 parts of guanidine hydrochloride, 1.2‑3.5 parts of sodium carbonate, 8‑23 parts of graphene. The beneficial effects of the present invention are: the novel cement grinding aid of the present invention effectively improves the friability and dispersibility of materials, improves the utilization rate of mechanical energy and reduces the cement production cost.

Description

technical field [0001] The invention relates to a novel cement grinding aid. Background technique [0002] Cement grinding aid is a chemical additive that improves the grinding effect and performance of cement. It can significantly increase the output of cement table, the strength of cement of all ages, and improve its fluidity. As a product used in the cement industry chain, cement grinding aid has become one of the indispensable raw materials in the grinding process of many cement production enterprises. It can bring real benefits to cement enterprises, and its main function is to improve The hourly output of the cement grinding system, obtaining reasonable process operating parameters, increasing the strength of cement at various ages, reducing the amount of clinker, increasing the amount of mixed materials, reducing the comprehensive power consumption of cement production, and improving the comprehensive profitability of the enterprise. In recent years, with the advan...
