Abstract
The present invention relates to a cement composition containing water, hydraulic cement, inert products and a foaming agent obtained by reacting ethylene oxide with a substrate deriving from the production of synthetic alcohols by the oxosynthesis of normal-olefins, sulfating the ethoxylate compound thus obtained with sulfuric anhydride and neutralizing the sulfated acid product with a base of an alkaline, earth-alkaline metal or ammonia. The cement composition can optionally contain conventional additives such as stabilizers, set retarders or accelerators and disperding agents suitable for lowering the viscosity of the composition. This cement composition has improved processability characteristics and enables the production of lightweight concretes having greater mechanical resistance and durability and lower thermal conductivity particularly appropriate for the building industry.
