Abstract
The invention relates to novel ordinary Portland P.O42.5 cement. The cement comprises the following components by weight percent: 78-82% of clinker, 4-6% of limestone, 4-6% of slag, 4-6% of fly ash and 4-6% of desulfurization gypsum. The cement has the advantages that industrial waste slag ingredients generated in the production processes in steel mills are adopted, thus not only reducing the production cost but also eliminating pollution sources, achieving economical efficiency and environment friendliness, improving the later strength of the cement and ensuring the quality of engineering construction.
Description
Technical field
The invention belongs to building material technical field, relate to general purpose portland cement, especially a kind of novel normal silicate P.O42.5 cement.
Background technology
General purpose portland cement is with Portland clinker and an amount of gypsum, and the hydraulic cementing materials made of the mixing material of regulation, uses very extensive.Existing normal silicate P.O42.5 cement shows aspect intensity, impermeability, water-retentivity, erosion resistance and wear resistance generally, also can only be applied to the common engineering building.Therefore, it is very necessary seeking the stronger novel normal silicate P.O42.5 cement of a kind of function.
By retrieval, find following two pieces of relevant publication documents:
1, a kind of modified portland cement composite material and make section thickness take it as gelling material and be the method (CN1081168) of 6-20 millimeters building slab, in ordinary Portland cement, to mix fineness less than 20% pozzolanic materials 20%-50%, the building slab of add again sand, water and fortifying fibre, making, need 50 ℃ of-90 ℃ of temperature, humidity reaches under 80%-100% the condition carries out maintenance.
2, a kind of composite silicate cement (CN1122784) be the artificial volcanic ash blended material made through vertical shaft kiln roasting take rubbish and shale, clay as raw material as adulterant, form take silicate cement as the base material mix.The blended amount of its blended material is 30%-40%, and the highest volume can reach more than 60%, and generally the ultimate compression strength than grog 28d only reduces 3.3%-7.7%, and can improve the cement clinker stability, and solves the ubiquitous stability problem of shaft kiln cement; Its product has early strong, stable, high hardness and fastness to rubbing, the low performances such as perviousness; Production technique is simple, facility investment economizes very much, and manufacturing cost is very cheap, simultaneously energy treating refuse, improvement environment.
By the technical characterictic contrast, above-mentioned publication document and the present patent application have more different.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, propose a kind of novel normal silicate P.O42.5 cement, this cement proportion science, and intensity is high, wear resistance is good, with low cost.
The objective of the invention is to be achieved through the following technical solutions:
A kind of novel normal silicate P.O42.5 cement, it consists of component and weight percentage ranges is respectively:
Grog 78-82%
Wingdale 4-6%
Slag 4-6%
Flyash 4-6%
Desulfurated plaster 4-6%.
And, described material is mixed according to weight proportion, evenly grinding can become finished product in cement grinding mill.
Advantage of the present invention and positively effect are:
1, the slag of institute of the present invention admixture can increase the 2-4 MPa to 28 days intensity of cement, reduces hydration heat, is conducive to the crack that prevents that internal temperature rise of mass concrete from causing.In addition, the cement of admixture slag can make maturing have good sulphate-corrosion resistance, reduce and inhibition chlorion diffusion, and anti-marine denudation, anti-carbonization, alkali resistant.。
2, the flyash of institute of the present invention admixture has increased grindability, when improving platform 2-5t/ hour, has improved in addition the elementary divergence increase of cement adaptability and has reached 20-40mm.
3, the desulfurated plaster of institute of the present invention admixture further reduces cement cost, ton cement ingredient cost ratio adds the plaster of paris and reduces by 4 yuan/tons, replace the plaster of paris to do the retardant of producing cement with desulfurated plaster, the comprehensive utilization waste residue is turned waste into wealth, both saved gypsum resource, again can contaminated solution, bring good economic benefit and social benefit for society and enterprise, improve thus 3 days intensity 1-2 MPas.
4, the present invention adopts the industrial waste Slag Mixture that produces in steel mill's production process, has not only reduced production cost, and has eliminated source of pollution, economic environmental protection.Adopt Slag Mixture, improved the later strength of cement, guarantee the quality of engineering construction.
