Abstract

The present invention proposes concrete specific complex flyash and preparation method thereof, can reach to make full use of resource, reduce cost, reduces the consumption of flyash, improves the purpose of the workability of concrete.Concrete specific complex flyash, by mass percentage, raw material forms: dolomite 55% 65%, lime mud 5%, plant slag 15% 20%, flyash 5%, boiler slag 5%, deposed brick slag 5% 10%.Its preparation method is: (1) raw material prepares and pretreatment, and various raw materials are broken into the graininess of particle diameter≤25mm;(2) raw material is delivered to respectively mixing bunker by metering conveyor, mixes;(3) raw material of mixing is delivered to vertical mill through jigging conveyer grind, it is ensured that granularity≤45 μm, is finished product.The concrete specific complex flyash that the present invention proposes is the substitute of the admixture flyash being exclusively used in commerical ready-mixed concrete.

Description

Concrete specific complex flyash and preparation method thereof
Technical field
The invention belongs to concrete admixture field, especially concrete specific complex flyash and Preparation method.
Background technology
The admixture that concrete market is main at present is flyash, and it is to be fired through high temperature by power plant's coal dust Burn and collect;In concrete, adding coal ash can save part of cement and fine aggregate;Decrease and use water Amount;Improve the service behaviour of the workability Concrete Structure of concrete batching system;Decrease Xu of concrete Become;Reduce the heat of hydration, heat energy dilatancy;Improve concrete impervious ability;Increase the modified of concrete.
Along with the abatement day by day of natural resources, coal is non-renewable natural resources, flyash Application is increasingly wider, and flyash also shows precious, and the market price goes up, and result in commerical ready-mixed concrete cost Rise.
Summary of the invention
In order to make full use of resource, reduce cost, reduce the consumption of flyash, improve concrete Workability, the present invention uses blend modification technology to propose concrete specific complex flyash and preparation method thereof.
Hereinafter, technical scheme is described.

Described deposed brick slag refers to: building or the useless brick of sandstone brickyard abandoned, then pulverizes and forms;
(1) raw material prepare: by mass percentage, dolomite 55%-65%, lime mud 5%, Plant slag 15%-20%, flyash 5%, boiler slag 5%, the consumption of deposed brick slag 5%-10% prepare; Various raw materials, through pretreatment, are broken into the graininess of particle diameter≤25mm;
(2) carry and mix: by metering conveyor, raw material being delivered to mixing bunker respectively, enter Row mixing;
(3) grind: the raw material of mixing is delivered to vertical mill through jigging conveyer and grinds, protect Card granularity≤45 μm, is finished product.
Beneficial effect: the present invention simulates pozzolanic material, use quarry refuse, fly ash in electric power plant, The industrial residues such as boiler slag, lime mud, plant slag, deposed brick slag, use blend modification technology (be by Two or more material in appropriate proportion, by being blended, is beyond one's reach obtaining homogenous material In the case of performance guarantee intensity is constant, admix soft polyhybird material, the material saved material) concrete is special Composite fly ash.Described concrete specific complex flyash is the admixture flyash being exclusively used in commerical ready-mixed concrete Substitute.
Detailed description of the invention
