摘要：
PURPOSE: A concrete having uniform density and high strength is produced by curing a pump able aqueous concrete mixture which has an air pore volume of 10-85 vol.% and comprises an anionic surface-active compound containing two sulphonic acid groups and having an air-entraining effect. CONSTITUTION: A pump able aqueous concrete mixture having an air pore volume of 10-85 vol.% is produced by introducing water, an anionic surface-active compound and, optionally, other organic additives as well as cement of 2-40 wt.%, based on the total amounts of cement, agitating the added ingredients while entraining air to a homogeneous, stable, air-containing concrete mixture, and then adding in one or more steps or continuously during agitation the remaining amount of cement. A concrete having an air pore content of 15-90 is cast from a pump able aqueous concrete mixture obtained by adding, when preparing the mixture, an anionic compound in an amount of 0.005-1 wt.%, based on the weight of cement, as a stabilizing and air-entraining agent.
摘要（中）：
目的：具有均匀密度和高强度的混凝土是通过固化具有10-85体积％的空气孔体积的含水混凝土混合物并且包含含有两个磺酸基并具有空气的阴离子表面活性化合物 增强效应。 构成：通过引入水，阴离子表面活性化合物和任选的其它有机添加剂以及2-40重量％的水泥产生具有10-85体积％的空气孔体积的可泵水性混凝土混合物， 基于水泥的总量，搅拌添加的成分，同时将空气带入均匀，稳定的含空气混凝土混合物中，然后在搅拌期间一次或多步加入剩余量的水泥。 空气孔隙含量为15〜90的混凝土是通过在制备混合物时加入一种以水泥重量计0.005-1％（重量）的阴离子化合物， 作为稳定剂和加气剂。
