Description
Technical field
The invention belongs to building material field, more particularly to a kind of alkaline residue pervious concrete and preparation method thereof.
Background technology
In October, 2014, house and town and country construction portion put into effect《Sponge urban construction technical manual》, instructed from technological layer
Carry out sponge urban construction in various regions.16 cities are determined within 2015 as pilot, and following 3 years, average each experimental city is annual
About hundred million yuan of sponge urban construction special funds will be obtained, a large amount of is the important measure of sponge urban construction using pervious concrete.
Alkaline residue refers to the alkaline scrap material discharged during alkaline and alkali process in industrial production.Comprising ammonium alkaline process alkali producing process
The waste residue of middle discharge and the alkaline scrap material of other industrial processes discharge.This bulk deposition is adversely affected to environment
Waste material, dispersion is applied in sponge urban construction in laying the pervious concrete of humanoid road, has not only embodied commercial value but also reality
Environment protection significance is showed.
The present invention forms a kind of hydraulicity gelling material material by alkaline residue activated slag, largely replaces portland cement.
Theoretical foundation of the invention is alkali-activated slag, and stronger chemical bond is formed using soda ash NaOH activated slags.Alkaline residue is applied
Wherein contain a certain amount of salkali waste, the Binder Materials of some strength is formed using its activated slag, realize alkaline residue reproducible utilization, make
It is standby go out a kind of alkaline residue activated slag as Binder Materials pervious concrete.
The content of the invention
It is an object of the invention to provide a kind of alkaline residue pervious concrete, the same of existing pervious concrete intensity is being reached
When, industrial waste alkaline residue is rationally utilized, reduce cement consumption and cost.
The present invention also aims to provide a kind of preparation method of above-mentioned alkaline residue pervious concrete.
To achieve these goals, the solution of the present invention is：
A kind of alkaline residue pervious concrete, its every cubic metre component is：80~145kg of alkaline residue, 80~120kg of cement, ore deposit

Present invention also offers the preparation method of above-mentioned alkaline residue pervious concrete, comprise the following steps：
A. alkaline residue is pre-processed, is crushed and crossed 4.76mm square hole screens；
B. in the alkaline residue of aforementioned proportion, cement, slag, water being put into forced mixer successively, 1min is stirred；
C. rubble is put into again, stirs 2min；
D. divide three layers respectively to vibrate 25 times to be molded, you can prepare alkaline residue pervious concrete.
It is of the invention to be had the advantages that compared with present technology：
(1) portland cement needs to consume substantial amounts of mineral resources and the energy in process of production, discharges a large amount of titanium dioxides
Carbon, also brings dust and noise pollution, has not met the requirement of energy-saving and emission-reduction, Green Sustainable.
(2) by alkaline enterprise a large amount of alkaline residue discarded objects that pile up like a mountain, the technology of preparing of pervious concrete is applied to.
Reduce conventional processing mode such as to pile up, fill out the secondary pollution that sea is brought, not only processed industrial refuse but also brought practicality
And commercial value.
