Abstract：This paper studied the influence of different types of air-entraining additive and content on working ability, compressive strength as well as appearance quality of C35. The results show that improvement effect of A rosin type air-entraining agent on workability is the best. On the premise of meeting the properties of concrete mixing materials,the lowest content of A rosin type air-entraining agent,can made the minimum number of bubbles,minimum ratio of gross blowhole,highest compressive strength and optimum appearance quality. The field investigation shows that pumping effect of concrete mixing materials produced by A rosin type air-entraining agent is favorable with qualified rebound strength of the body and appearance quality of meeting concrete requirements.
