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
Often adopting the protection of concrete structure at present has a lot to the method for concrete outside surface coating material; in osmosis type material; as: the material taking water glass as principal constituent; by waterproof place and maintained treatment coating or inject water glass be the material of principal constituent, reach protection concrete structure object.But this material exists and to cause because main body is single water glass speed of response in concrete fast, poor permeability and generate the problems such as surperficial membranoid substance destruction easy to wear.
On the other hand, along with concrete structure becomes increasingly complex, some structure formations or structure privileged sites are as vertical thin wall constructions such as the side wall of concrete basement etc., its concrete maintenance is very difficult, and moisture is easy to lose, and, the engineerings such as the concrete road of constructing during the broiling summer, airfield runway, port and pier, when high temperature, moisture evaporation is very fast, easily causes concrete dry and cracked, affects the work-ing life of buildings.
Summary of the invention
The technical problem to be solved in the present invention is: overcome deficiency of the prior art, provides a kind of anti-corrosion concrete of corrosion-resistant, good water-retaining property, crack resistence.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of anti-corrosion concrete, described concrete mass parts is composed as follows: silicate cement 200-250 part, polymer emulsion 60-80 part, film coalescence aid 10-30 part, dispersion agent 5-10 part, breeze 20-40 part, rust inhibitor 8-15 part, gas tracting subtractive agent 6-8 part, water 100-150 part, water glass 5-10 part, potassium silicate 1.5-3.5 part, abrasion-resistant corundum filler particles 10-15 part, frostproofer 3-8 part, accelerating chemicals 2-5 part.
Further, described polymer emulsion is selected from the mixture of one or both arbitrary proportions in pure acrylic latex or benzene emulsion.
Further, described dispersion agent adopts polycarboxylate cement dispersant.
Further, described film coalescence aid is selected from the one in ethylene glycol, butyl glycol ether.
Further, the diameter of described breeze is 0.1-100nm.
Further, described concrete mass parts is composed as follows: silicate cement 200 parts, polymer emulsion 65 parts, film coalescence aid 20 parts, dispersion agent 8 parts, breeze 30 parts, rust inhibitor 12 parts, gas tracting subtractive agent 8 parts, 120 parts, water, water glass 8 parts, potassium silicate 3 parts, abrasion-resistant corundum filler particles 12 parts, frostproofer 5 parts, accelerating chemicals 3 parts.
The beneficial effect of technical scheme of the present invention is adopted to be:
1, adopt abrasion-resistant corundum filler particles as wear-resistant component, with the use of breeze and frostproofer, greatly improve wear resisting property and antiseptic property, with low cost, use technology is also very convenient, effectively can extend the work-ing life of buildings, reduce maintenance cost to a great extent;
2, with the addition of polymer emulsion, film coalescence aid, rust inhibitor in the present invention, further increase concrete antiseptic property, and the low in raw material price of use, reasonable ratio, effectively extends concrete work-ing life.
