Abstract
Abstract This invention is concerned with a polymer concrete composition, which is a two-component composition useful with many bases including metal. Component A, the aggregate composition, is broadly composed of silica, silica flour, portland cement, and acrylamide, whereas Component B, which is primarily vinyl and acrylyl reactive monomers, is a liquid system. A preferred formulation emphasizing the major necessary components is as follows: -Component A: -Silica sand 60-77 wt. % -Silica flour 5-10 wt. % -Portland cement 15-25 wt. % -Acrylamide 1-5 wt. % -Component B: -Styrene 50-60 wt. % -Trimethylolpropane 35-40 wt. % -trimethacrylate - and necessary initiators, accelerators, and surfactants.
