Abstract
A cellular cement composition having a low specific gravity and a high tensile strength is described in which an alkali metal alkylbenzenesulfonate and a metal chloride are added to cement, inert fillers and water. Additional components which accelerate setting and hardening speeds as well as modify the viscosity of the composition prior to setting can also be present.

A light, high tensile strength cellular cement composition having a homogeneous distribution of microporosities of diameters of from 0.1 to 4 mm sufficient to produce a specific gravity of from about 800 k/m.sup.3 to about 1600 k/m.sup.3, said composition containing from about 300 to 800 k of cement per m.sup.3 of composition, up to 1000 k of inert fillers per m.sup.3 of composition and from 36 to 68% water by weight of composition, and further containing an alkali metal alkylbenzenesulfonate in an amount of from 1 to 45% by weight of water and a metal chloride in an amount of from 2 to 35% by weight of water.
