Abstract
The invention relates to a roof concrete additive. The roof concrete additive is composed of the following raw materials in parts by weight: 20 to 40 parts of polycarboxylic acid water reducer, 2 to 7 parts of methyl cellulose, 15 to 25 parts of sodium gluconate, 5 to 10 parts of cellulose grafted chitosan, 15 to 20 parts of silane coupling agent, 10 to 15 parts of polyacrylamide, 3 to 8 parts of polyvinylpyrrolidone, 5 to 10 parts of sodium sulfate, 4 to 10 parts of silicon carbide, and 10 to 20 parts of fly ash. The provided roof concrete additive has the advantages that the addition amount of the additive is little, the additive can be well dispersed in concrete, and moreover, the additive can effectively inhibit or reduce the generation of biological sulfuric acid in a long time, enhance the bearing performance of concrete structure, and prolong the service life.
Description
Technical field
The present invention relates to a kind of Roof concrete addictive.
Background technology
Concrete is as existing more than the 100 year history of material of construction, concrete advantage is, ultimate compression strength is high, draw materials easily, easy-formation is cheap, can be combined make various heavy firmware with other materials, but concrete deadly defect is that tensile strength is low, easy to crack, thus reduce the supporting capacity reduction of service life of concrete structure, become the hidden danger of various disaster accident.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of Roof concrete addictive.
Described a kind of Roof concrete addictive, it is characterized in that various starting material are calculated as follows according to mass fraction: polycarboxylate water-reducer 20-40, methylcellulose gum 2-7, Sunmorl N 60S 15-25, cellulose graft chitosan 5-10, silane coupling agent 15-20, polyacrylamide 10-15, polyvinylpyrrolidone 3-8, sodium sulfate 5-10, silicon carbide 4-10, flyash 10-20.
Described a kind of Roof concrete addictive, it is characterized in that various starting material are calculated as follows according to mass fraction: polycarboxylate water-reducer 25-35, methylcellulose gum 3-6, Sunmorl N 60S 18-22, cellulose graft chitosan 6-8, silane coupling agent 16-18, polyacrylamide 12-14, polyvinylpyrrolidone 5-7, sodium sulfate 7-9, silicon carbide 6-8, flyash 13-17.
Described a kind of Roof concrete addictive, it is characterized in that various starting material are calculated as follows according to mass fraction: polycarboxylate water-reducer 30, methylcellulose gum 5, Sunmorl N 60S 20, cellulose graft chitosan 7, silane coupling agent 17, polyacrylamide 13, polyvinylpyrrolidone 6, sodium sulfate 8, silicon carbide 7, flyash 15.
Gained admixture of the present invention adds in concrete, has that volume is few, good dispersity, can effectively and the suppression of dauer effect or reduce the generation of biological sulfuric acid, the supporting capacity reduction of service life of Concrete Structure structure.
