Cement admixture having superior water-reducing properties, method for preparing the same, and cement composition comprising the same |
| abstract |
The present invention relates to a cement admixture, wherein the cement admixture comprises at least one of a carboxylic acid copolymer containing a reactive surfactant as a monomer, and a copolymer salt obtained by further neutralizing the copolymer with an alkaline substance, and a method for preparing the admixture. And it provides a cement composition using the same.n n n The cement admixture of the present invention improves the dispersibility of the cement particles to improve the fluidity of the composition even in the region of high susceptibility, prevents the fluidity deterioration with time, and at the same time continuously operates the appropriate amount of air to impart good workability to the cement composition To form a concrete having high strength. |
