Abstract
The invention relates to the technical field of building materials, and particularly relates to anti-corrosion concrete, which comprises the following components in parts by weight: 200-250 parts of portland cement, 60-80 parts of a polymer emulsion, 10-30 parts of a film-forming additive, 5-10 parts of a dispersant, 20-40 parts of mineral powder, 8-15 parts of a rust inhibitor, 6-8 parts of an air entraining and water reducing agent, 100-150 parts of water, 5-10 parts of sodium silicate, 1.5-3.5 parts of potassium silicate, 10-15 parts of wear-resistant corundum filler particles, 3-8 parts of an antifreeze and 2-5 parts of an accelerator. The anti-corrosion has the beneficial effects that the wear-resistant corundum filler particles as a wear-resistant component is matched with the mineral powder and the antifreeze, so that the wear resistance and corrosion resistance are greatly enhanced, the cost is low, the use and maintenance are also very convenient, the service life of a building can be effectively prolonged, and the maintenance cost is greatly reduced.
Description
Technical field
The present invention relates to building material technical field, especially a kind of anti-corrosion concrete.
Background technology
At present the protection of xoncrete structure is had much frequently with to the method for concrete outer surface coating material, permeating
In section bar material, such as: the material with sodium silicate as main constituent, by waterproof with helpdesk coating or injection sodium silicate based on become
The material dividing, to reach the purpose of protection xoncrete structure.But this material exists because main body is single sodium silicate and causes in coagulation
In soil, response speed is fast, poor permeability and the problems such as generate surface membranoid substance destruction easy to wear.
On the other hand, become increasingly complex with xoncrete structure, some versions or structure privileged sites such as concrete
Vertical thin-wall construction such as side wall of basement etc., the maintenance of its concrete is extremely difficult, and moisture is easy to lose, and,
The engineerings such as the hot concrete road of hot weather construction, airfield runway, port and pier, in high temperature moisture evaporation quickly, easily
Cause the dry and cracked of concrete, the service life of impact building.
Content of the invention
The technical problem to be solved in the present invention is: overcomes deficiency of the prior art, provides a kind of corrosion-resistant, water-retaining property
The good, anti-corrosion concrete of crack resistence.
For solving above-mentioned technical problem, the technical solution used in the present invention is as follows:
A kind of anti-corrosion concrete, the mass parts composition of described concrete is as follows: portland cement 200-250 part, polymer
Emulsion 60-80 part, coalescents 10-30 part, dispersant 5-10 part, breeze 20-40 part, corrosion inhibitor 8-15 part, gas tracting subtractive agent
6-8 part, water 100-150 part, sodium silicate 5-10 part, potassium silicate 1.5-3.5 part, abrasion-resistant corundum filler particles 10-15 part, antifreezing agent
3-8 part, accelerator 2-5 part.
Further, described polymer emulsion be selected from one of pure acrylic latex or styrene-acrylic emulsion or two kinds arbitrarily than
The mixture of example.
Further, described dispersant adopts polycarboxylate cement dispersant.
Further, described coalescents are selected from one of ethylene glycol, butyl glycol ether.
Further, a diameter of 0.1-100nm of described breeze.
Further, the mass parts composition of described concrete is as follows: 200 parts of portland cement, 65 parts of polymer emulsion, one-tenth
20 parts of film auxiliary agent, 8 parts of dispersant, 30 parts of breeze, 12 parts of corrosion inhibitor, 8 parts of gas tracting subtractive agent, 120 parts of water, 8 parts of sodium silicate, silicic acid
3 parts of potassium, 12 parts of abrasion-resistant corundum filler particles, 5 parts of antifreezing agent, 3 parts of accelerator.
Beneficial effect using technical scheme is:
1st, adopt abrasion-resistant corundum filler particles as wear-resistant component, with the use of breeze and antifreezing agent, greatly improve resistance to
Mill performance and antiseptic property, with low cost, use and keep in repair also very convenient, can effectively extend the service life of building, very greatly
Maintenance cost is reduced on degree；
2nd, with the addition of polymer emulsion, coalescents, corrosion inhibitor in the present invention, further increase the anti-corrosive properties of concrete
Can, and, the low in raw material price of use, reasonable mixture ratio, effectively extend the service life of concrete.
