Integral foamed concrete

Date: 2009
The production of concrete causes a substantial part in the CO2 emission worldwide. The use of light-weight concrete elements diminish this and helps to solve the ergonomic constraints in the building industry by weight reduction. Concrete elements of which only the kernel is foamed and the outside layer is solid have the advantage of high quality hard surface, no assimilation with water and a better surface strength compared with regular aerated concrete. In a first experiment a proof of principle was carried out successfully to realize such a concrete element. With this method the weight of a pre-fab element could be reduced by more than 50%.
