掺入松香热聚物引气剂对混凝土强度影响研究

Study on the influence of rosin pyrolytic polymer-type air entraining agent on concrete strength

通过对松香热聚物引气剂掺量为0．0025％～0．025％混凝土的配制，研究了松香热聚物引气剂的引气能力，论述了在水泥用量和水灰比相同的情况下引气剂不同掺量对混凝土3d，7d和28d抗压强度的影响，从而得到混凝土中引气剂的最佳掺量。

In this paper, by compounding a concrete in which a rosin pyrolytic polymer-type air entraining agent have been adulterated and its dosage is 0. 002 5% to 0. 025%, we have researched the ability of rosin pyrolytic polymer-type air entraining agent to attract the gas, as well as the concrete 3 d, 7 d and 28 d intensity influence came from different dosage of air entraining agent in the condition of same useage of cement and same water cement ratio. In the end, we obtain the most reasonable dosage of air entraining agent in concrete.
