Abstract

Seven brands of air-entraining and high-range water-reducing admixture containing viscosity modifying agent (VSP) were compared by mortar test. As a result, it was shown that several VSP required the surplus dosage. And the surplus dosage brought increase of the high viscosity of mortar. In the case of surplus dosage, the difference in flow time of funnel test of fresh mortar between VSP and air-entraining and high-range water-reducing admixture (SP) was over 10 seconds. Therefore, when using VSP, it's important to decide dosage at the range of standard dosage of each manufacturer.
