COMPOSITE BUILDING MATERIAL
A method of pouring a body, including mixing an isocyanate, a polyol, and a catalyst to yield an admixture, dispersing a particulate phase in the admixture to yield a homogeneous composition, pouring the homogeneous composition into a preform, capping the preform to prevent expansion of the homogeneous composition thereoutof, and curing the homogeneous composition to yield a polymeric composite body. The matrix portion is formed from a polymerizable formulation comprising at least one isocyanate precursor, at least one polyol, and a catalyst contained in a mold having a pressure rating of at least 0.4 Mpa. The at least one isocyanate precursor is selected from the group consisting of polymethylene polyphenylisocyanate, diphenylmethane diisocyanate, triphenylmethane triisocyanate, toluene diisocyanate and methyl diisocyanate (MDI), and combinations thereof. The catalyst is selected from the group consisting of a dialkyltin derivative, tributyl bismuth, and combinations thereof and is a tertiary amine.
