ABSTRACT:
Previous weather resistant cementitious compositions in which succinic acid derivatives were incorporated to improve weather resistance have been found to suffer from an undesirable decrease in compressive strength. In accordance with the invention, compressive strength is significantly increased without substantially reducing weather reistance by adding an antifoam agent to the mixture prior to setting into a solid.
