Abstract
The invention relates to a road paving material prepared from phosphogypsum composite residues and a preparation method thereof. By recovering and reutilizing waste phosphogypsum and residues, the method is energy-saving and environment-friendly. The material and method can be widely used for road engineering construction.
Description
Technical field
The present invention relates to a kind of urban road laying material with the compound dregs of phosphogypsum and preparation method thereof, by discarded phosphogypsum and the energy-conserving and environment-protective of dregs resource utilization recycling, this material and method can be widely used in road project.
Background technology
Phosphogypsum is a kind of industrial by-products, has a large amount of phosphogypsum outputs in the annual industrial production of China, less owing to recycling, and itself environment is had to larger pollution, and how processing these discarded phosphogypsums is a great problems.In building operation construction, usually can produce in addition a large amount of discarded dregs, it comprises discarded concrete, fragment of brick, rubble etc., is landfill, stacking etc. at present to its main processing mode, does not effectively utilize.And in Road construction, often need a large amount of solid materials, but discarded phosphogypsum and dregs be not suitable for directly as raw material.The present invention attempted utilizing above-mentioned two kinds of solid waste as raw material for urban road laying material.
Summary of the invention
The object of this invention is to provide a kind of urban road laying material with the compound dregs of phosphogypsum and preparation method thereof.Its technical scheme is as follows:
Comprise following raw material (by weight),
Phosphogypsum 50-100 part;
Dregs 30-60 part;
Lime 10-15 part;
Active superfine micro mist 10-15 part, wherein said active superfine micro mist is volcanic ash, its specific surface area is 500-1800m2/kg;
Nano-calcium carbonate 2-3 part.
Graphene dispersing solution 2-3 part, described graphene dispersing solution is Graphene to be placed in to deionized water through ultrasonic dispersion, within 0.5-1 hour, obtain again, Graphene: deionized water (by weight)=1: 100-250, wherein said Graphene thickness is 20-40 nanometer, Graphene diameter 10 nanometer-200 nanometers;
Exciting agent is the 0.02-0.06% (by weight percentage) of raw material gross weight, described exciting agent is compound bio solidifying agent, the present invention also can adopt alkaline compound activator, alkalescence compound activator is water glass and sodium hydroxide, wherein water glass: sodium hydroxide=2: 1.5-2.5 (by weight);
Redispersable latex powder 2-4 part;
Hardening accelerator 1-2 part;
Water-resisting agent 1-2 part;
Polycarboxylate water-reducer 1-2 part;
In the raw material of this urban road laying material, do not comprise cement, pitch and cement concrete.
The preparation method of above-mentioned urban road laying material, comprises the steps:
A, according to proportioning, take respectively above-mentioned raw materials;
B, phosphogypsum powder is broken into particulate state;
C, dregs is broken, then process through screening, sieve diameter is less than or equal to 5mm;
D, by each raw material mixing and stirring.
Described Graphene can be obtained by commercially available or prior art preparation.
Excellent technique effect of the present invention: its main raw material adopts discarded phosphogypsum and dregs, pass through compound activator, superfine active micro mist, the raw materials such as lime have improved the water-absorbent of phosphogypsum, stability and paver intensity, the dregs of pulverizing is as the aggregate raising intensity of can playing a supporting role, utilize the excellent mechanical strength performance of Graphene, make nano-calcium carbonate and graphene dispersing solution fill the fine gap in curing system, curing system dense substrate strength stability is further strengthened, water-resisting agent, hardening accelerator and polycarboxylate water-reducer can improve the resistance to compression of product, impervious, the performances such as intensity, the synergy of described raw material and proportioning and admixture makes the described compound dregs paver of phosphogypsum have good performance simultaneously.
