Abstract

The invention discloses a rapid geopolymer-based road repairing material which is mainly prepared from the following components in parts by weight: 5-10 parts of red mud, 8-15 parts of excitant, 25-40 parts of mineral slag, 10-15 parts of coal ash, 10-15 parts of calcined coal gangue, 5-10 parts of steel slag, 1-5 parts of micro silicon powder, 0.5-1 part of retarder and 0.1-0.5 part of water-soluble resin rubber powder. The preparation method of the rapid geopolymer-based road repairing material comprises the following steps: drying and crushing red mud so as to obtain dried red mud powder of which the water content is smaller than 5%; adding various raw materials into a zero-gravity mixing stirring machine according to the ratio, and stirring for 10 minutes; putting the stirred material into a dampproof packaging bag. The rapid geopolymer-based road repairing material has the advantages of high construction speed, low cost, rapid coagulation curing, high strength, environment-friendliness and the like. Compared with a cement-based repairing material, the rapid geopolymer-based road repairing material has the characteristics that the cost is lowered as a great deal of industrial waste solid slag is used, the strength and the coagulation efficiency of an injecting paste material are improved due to adoption of a geopolymer material synthesis technique, the flowability is improved, the amount of the industrial solid wastes is great, and the production is green and environment-friendly.

Description

A kind of ground polymers base Rapid Road Patching Material

Technical field

The present invention relates to a kind of ground polymers base Rapid Road Patching Material, belong to building material technical field.

Background technology

A large amount of coagulation soil matrix highway life-time service or be subject to loaded vehicle and roll, surface there will be the disrepair phenomenons such as cracking, hollow place, fracture, needs the road surface of repairing these breakages in time.Cement concrete is selected to repair at present, cement concrete is in mending course, and concrete needed to spend longer time maintenance before reaching final strength, and maintenance will inevitably arrange the means such as isolation, this will certainly cause road to be obstructed, very large to traffic impact.

Ground polymers is for the material that is excited with the activated silica-aluminum materials of tool, with high reactivity basic material for exciting agent, after the two mixing under certain conditions, by a kind of inorganic polymer polymeric material with three-dimensional network-like structure that the process of separating poly-polycondensation is formed, therefore this kind of material has excellent performance, such as, have that the intensity of superelevation, rapid reaction, durability degree are excellent, good corrosion resistance, fire prevention, perviousness is low, raw material sources is abundant.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of ground polymers base Rapid Road Patching Material, and this material speed of application is fast, and condensation cure is fast, and intensity is high, solves the shortcoming that when conventional concrete acts on pavement patching, curing time is long.

The realization of foregoing invention object have employed following technical measures: a kind of ground polymers base Rapid Road Patching Material, and it mainly forms counts with parts by weight: red mud 5-10 part, exciting agent 8-15 part, slag 25-40 part, flyash 10-15 part, calcining coal gangue 10-15 part, slag 5-10 part, SILICA FUME 1-5 part, retardant 0.5-1 part, water soluble resin rubber powder 0.1-0.5 part;

Described red mud is the Bayer process red mud of water content at 5%-30%;

Described exciting agent is commercially available technical grade sodium silicate, its modulus m=1.5-2.5, and degree Beaume is 40;

Described slag is fineness 100-600 object blast furnace granulated slag;

Described flyash is any one or arbitrary proportion mixture in commercially available one-level, second class powered coal ash;

Described calcining coal gangue is calcine 2 hours at 800 DEG C, and its fineness is 100-500 object powder;

Described slag is after crushing and screening, the particle of its size distribution within the scope of 80-150 order;

Described SILICA FUME is that fineness is greater than 1000 object commercially available prod;

Described retardant is the one or any scalemic thereof in commercially available industrial SODIUM PHOSPHATE, MONOBASIC, sodium hydrogen phosphate;

The preparation method more than filled a prescription is as follows:

1, by red mud drying, fragmentation, the dry red mud powder that water content is less than 5% is obtained;

2, various raw material is proportionally joined in agravic mixing and blending machine, stir 10min;

3, the material be stirred is encased in moisture-proof packing bag, obtains final product.

Take the present invention of above-mentioned measure, based on ground polymers synthetic materials technology, be starting material with solid slag, take water glass as cement-base quick repairing material prepared by exciting agent, there is the advantages such as speed of application is fast, with low cost, condensation cure is fast, intensity is high, environmental protection.

Compared with existing cement-base quick repairing material, main advantage has: 1, a large amount of employing industrial solid waste residue, reduces cost; 2, inorganic polymer polymerization technique is adopted---ground polymer material synthetic technology, improves intensity and the calculus rate of injecting paste material greatly; 3, improve mobility; 4, Industrial Solid Waste consumption is large, protection of the environment, production environmental protection.
