Chemical-resistant polymer concrete and methods of use thereof are described herein. The polymer concrete comprises a polymer layer and aggregates. The polymer layer is formed by reacting an epoxy vinyl ester resin promoted with cobalt and catalyzed by a peroxide. A concrete substrate is formed by layering the polymer layer and aggregates in thin alternating layers until a desired thickness is achieved. This layering method can reduce shrinkage of the concrete, thereby preventing cracking, deformation or debonding.

A sanitary article, which has a support body and an outer coating which is applied to the support body at least in certain portions and forms the outer side of the sanitary article, the support body being of a first composite material of a filled polymeric binder matrix containing at least one filler in the form of hollow glass beads and the outer coating being of a second composite material of a polymeric binder matrix, which is filled with at least one filler and does not contain any hollow glass beads.

A composition for use in making a structural assembly board, a structural assembly made from the composition, and a method of making the structural assembly board is provided. The composition includes magnesium oxide having purity of 94-98 wt %; magnesium chloride; and water. The magnesium oxide has at least two different particles sizes. The composition and method of making the structural assembly board promote formation of 5MgO.MgCl.sub.2.8H.sub.2O to improve structural qualities of the structural assembly board.
