| titleOfInvention | Special superplasticizer for high and ultrahigh strength concrete and preparation method thereof |
| abstract | The invention discloses a special superplasticizer for high and ultrahigh strength concrete and a preparation method thereof. The preparation method of the superplasticizer comprises the following steps: initiating polymerization by using a solvent, a polymerizable monomer A, a chain transfer agent B, a polymerizable monomer I and an initiator to obtain an intermediate solution; then adding polyether C, amino acid D and small molecular peptide E, and simultaneously adding a reaction assisting reagent F to obtain an intermediate mixed solution; and adding the intermediate mixed solution into the mixed solution of the phosphoric acid composition G dissolved in the solvent and water to obtain the solution of the superplasticizer. Compared with the common superplasticizer sold in the market, the superplasticizer provided by the invention is applied to high-strength concrete with the fluidity of above C50, the using amount of the superplasticizer can be obviously reduced when the same fluidity is achieved, the workability is obviously improved under the same fluidity condition, the emptying time of a slump cone is shortened, and the viscosity is reduced; the concrete admixture is applied to the ultra-high-strength concrete with more than C100, has more outstanding advantages, and can obviously reduce the using amount and the viscosity. |
