Abstract
The present invention relates to a multifunctional cement grinding aid composed of fly ash, sodium chloride, triethanolmine, sodium silicate, stone powder of zinc ore, benzyl-trisodium, gypsum and diethylene glycol, wherein triethanolmine performs the functions of grinding aiding, no static electricity generation and reduction of coacervation and ball pasting of materials in a grinder, sodium silicate performs the function of increasing the stability of cement strength, stone powder of zinc ore performs the function of lowering the radiation of building materials to human bodies, benzyl-trisodium can lower the corrosion of concrete to reinforced bars, and diethylene glycol performs the function of grinding aiding, no static electricity generation and freezing protection convenient to construction in winter. The present invention has the advantages of high productive efficiency, favorable performance of technological operation, rust prevention, low cost, etc., and the performance and increased quality of cement. The use level of cement clinker is obviously reduced by 20%, the production cost of cement is lowered, and the economic benefit is obvious. The radiation of building materials to human bodies can be lowered, the multifunctional cement grinding aid is convenient to construction in winter, and the construction period can be extended to 15 DEG C below zero.
Description
Technical field
The invention belongs to the cement grinding technical field, particularly a kind of have antirust, be convenient to winter construction, reduce cement performance penetrated and improved by material of construction to the width of cloth of human body multifunctional cement grinding aid.
Background technology
Cement grinding aid can reduce the manufacture of cement cost, improves manufacture of cement efficient, increases cement output, improves cement performance and quality and improves the processing property etc. of cement production process.Be widely used in countries in the world.China is world manufacture of cement big country, and the research and development of cement grinding aid is very fast.Along with deepening continuously of applied research, cement grinding aid is not only considered the grinding-aid effect of traditional grinding aid, promptly increases cement grinding mill platform output when keeping identical fineness, improves the processing property of cement production process.Find that simultaneously grinding aid has cohesion that reduces material in the grinding machine and the effect of sticking with paste ball, improve material dispersed, improve cement performance and quality.At present, the cement grinding aid function singleness of production is especially not enough at raising cement performance and quality consciousness.Cement grinding aid of the present invention not only has the grinding-aid effect of traditional grinding aid, reducing production costs, enhance productivity, improve cement performance and effect is remarkable qualitatively, also have antirust, be convenient to the effect that winter construction and reduction material of construction are penetrated the human body width of cloth.
Summary of the invention
The objective of the invention is deficiency at existing cement grinding aid existence, a kind of grinding-aid effect that not only has traditional grinding aid is provided, production cost is low, the production efficiency height, also have antirust, be convenient to winter construction, reduce material of construction penetrated and improved cement performance and quality to the width of cloth of human body multifunctional cement grinding aid.
Multifunctional cement grinding aid of the present invention is the mixture of flyash, sodium-chlor, trolamine, water glass, zinc ore stone flour, benzene first trisodium, gypsum, Diethylene Glycol, and the weight ratio of its mixture is: flyash is 10～60%; Sodium-chlor 15～55%; Trolamine 5～35%; Water glass 0.05～10%; Zinc ore stone flour 0.3～12%; Benzene first trisodium 0.2～8%; Gypsum 0.5～6%; Diethylene Glycol 0.3～5%, wherein mainly to act on be to increase strength of cement, delay conditioned time to sodium-chlor; Trolamine has been that grinding aid soon, does not play cohesion and the paste ball that static reduces material in the grinding machine; Water glass has been the stability effect that improves strength of cement; The zinc ore stone flour has been to reduce the effect that material of construction is penetrated the width of cloth of human body; Benzene first trisodium can reduce the corrosion of concrete to reinforcing bar; Gypsum can make concrete play the rapid hardening effect; Diethylene Glycol has been that grinding aid soon, does not play static and antifreezely is convenient to the winter construction effect.
The present invention have production efficiency height, technological operation performance good, improve cement performance and quality, antirust and low cost and other advantages, and obviously reduce cement clinker consumption 20%, reduce the manufacture of cement cost, remarkable in economical benefits.Can also reduce material of construction the characteristics of winter construction are penetrated and be convenient to the width of cloth of human body, the construction time can be extended down to-15 ℃.
Embodiment
The composition and the test effect of multifunctional cement grinding aid of the present invention are described below in conjunction with example.
A kind of multifunctional cement grinding aid, the weight ratio of its composition and composition thereof is: flyash is 56%; Sodium-chlor is 18%; Trolamine is 15%; Water glass is 0.65%; The zinc ore stone flour is 3.2%; Benzene first trisodium is 2.5%; Gypsum is 0.5%; Diethylene Glycol is 4%.
Producing the cement raw material proportioning is: grog is 55%; Slag is 41%; Gypsum is 3%; Multifunctional cement grinding aid is 1%.At production unit is that 500mm * 500mm tests grinding machine; Experimental installation: planetary cement mortar mixer, ISO cement mortar testing table, the cement paste stirrer, cement mortar tryout, electronic anti-folding instrument is tested on the pressure testing machine etc.According to GB1344---1999 " Portland blast " standard and GB/T17671---1999 " Test method for strength of hydraulic cement mortar (ISO method) " assay such as table one:
Table one: add the cement test table that cement grinding aid is produced
