Abstract
An aqueous concrete mixture having an air pore volume between 10 and 85%, preferably between 20 and 85%. When the aqueous concrete mixture is cured, a concrete having uniform density and high strength is obtained. This is achieved by including in the concrete mixture an aqueous, anionic surface-active compound containing two sulphonic acid groups of the general formula (R).sub.m --R.sub.1 --(SO.sub.3 M).sub.2 (1) wherein R is an aliphatic group having 4-20 carbon atoms, m is a number 1 or 2, the sum of the number of carbon atoms in the 1 or 2 R groups being 6-30, R.sub.1 is an aromatic group containing at least 2 aromatic rings and 10-20 carbon atoms, and M is a cation or hydrogen. The anionic compound has an air-entraining effect and improves the homogeneity of the concrete mixture.
