| Abstract: | To solve the drawbacks of conventional hardening accelerating and water reducing admixture,through the orthogonal test,a new admixture was invented which is based on a polycarboxylate superplasticizer and some other hardening accelerants.This admixture has many characters,for example,chloride free,sulfate free,low total alkali content,low dosage,high water reducing rate,high early strength and so on. |

| Keywords: | polycarboxylate high early strength multifunctiona superplasticizer chloride free |
