Abstract: A method for producing hardened cellular concrete having normal compressive strength by producing tiny, unconnected, pre-pour, air-filled bubbles during mixing of cement, cementitious substitutes, sand, coarse aggregates, water, fiber, a surfactant, aluminum flakes or powder, calcium formate, and magnesium silico fluoride and then producing additional tiny, unconnected, post-pour, hydrogen-filled bubbles to replace those air-filled bubbles which are destroyed while pouring the fresh concrete during the casting operation. Only as much matrix is added to the coarse aggregate as is needed to engulf the aggregates while enabling the aggregate particles to be in contact.

Abstract: The present fiber reinforced cellular concrete is produced through a chemical reaction that does not require high heat or pressure ovens (autoclaves). Among its unique features, is the fact that different compression strengths can be obtained by varying the proportion of ingredients and resulting densities. The concrete utilizes a base of a pozzolanic product with aluminum powder, lime, calcium formate, cement, and polypropylene fiber is added, along with water. Expanded shale, clay or slate is added to provide lower shrinkage to the resulting mass reducing cracking. Optionally, sand and compatible reinforcing material can also be added.
