ABSTRACT:
A foam of very small, microscopic bubbles of surfactant, each bubble containing a small quantity of water, is mixed with a water/cement mixture having a water to cement ratio of less than 0.33. The small bubbles have a ball bearing effect on the smaller cement and sand particles, increasing plasticity or flowability and thus reducing the water requirements of the mixture. The foamed cement mixture is laid to form a desired concrete structure, and the bubbles disintegrate or transform to leave voids of similar size uniformly dispersed throughout the concrete structure.
