Abstract

Air-entraining agents have been regarded as essential for the workability of concrete since the 1930s, the uniform, stable tiny bubbles in concrete can improve the workability of concrete, reduce segregation and bleeding in fresh concrete, improve freeze-thaw durability and increase pump-ability of fresh concrete. In this work, we synthesize a new polyether air-entraining agent AE-x. By contrast with a variety of air-entraining agents, AE-x has a relatively good air entraining properties, AE-x also has good compatibility with Polycarboxylate Superplasticizers and other concrete admixtures, The hardened concrete with the addition of the AE-x exhibits a satisfactory pore size distribution system which is of higher porosity with small-size and lower porosity with large-size than other air-entraining agents.
