Concrete closed-cell micro-foam air entraining method
The invention relates to a concrete closed-cell micro-foam air entraining method. According to the method, 0.5-1 kg of an air entraining agent and 0.5-1 kg of a concrete plasticizing foam stabilizer are added into each cubic meter of concrete when the concrete is prepared. The air entraining agent is prepared from a surfactant AES, a surfactant AOS and water; the concrete plasticizing foam stabilizer is prepared from carboxymethyl cellulose, redispersible instant emulsion powder, polyacrylamide and mineral powder. The concrete air entraining agent and the concrete plasticizing foam stabilizer are used at the same time, the slump loss and segregation degree of the concrete can be reduced, the concrete is in a good plastic state for a long time, the influence of state factors is eliminated, and the air entraining amount and the bubble form are controllable.
本发明涉及一种混凝土闭孔微沫气泡引气方法，该方法是指配制混凝土时每方混凝土添加0.5~1kg的引气剂和混凝土增塑稳泡剂0.5~1kg。引气剂由表面活性剂AES、表面活性剂AOS和水制成；混凝土增塑稳泡剂由羧甲基纤维素、可再分散速溶乳胶粉、聚丙烯酰胺和矿粉制成。本发明同时使用混凝土引气剂和混凝土增塑稳泡剂，可降低混凝土坍损与离析程度，使混凝土长期处于良好的塑性状态，消除状态因素的影响，使引气量和气泡形态可控。
