Development strategies for foamed cement paste

authored by: J. U. Pott, L. Lohaus
Abstract: For several decades numerous research projects dealt with foamed concrete. Although foamed cement-bound materials have very useful properties, for example low density and low thermal conductivity, they are not often used as construction material, because predefined properties are difficult to attain accurately. Therefore the intention of this research work is the unerring production of cement-bound foams. Based on technical and scientific basics of foam technology and concrete technology, special attention is paid to the rheological behaviour, mixture stability and the hardening process of cement paste as the dominating factors for its optimisation as liquid phase for foamed cement paste. From these considerations a comprehensive model for stable cement-bound foams is developed. Within this model the complex interaction of different components of cement pastes and their influences during the phases of production, workmanship and hardening are described. According to the before mentioned aspects, a stable composition for a foamed cement paste was developed. Modifications of this composition have been tested, in order to prove the reliability of the theoretical model.
