Polymer concrete compositions and cured products thereof
First Claim
1. A composition suitable for use as a polymer concrete comprising (a) a granular aggregate having a void fraction of less than 0.37, (b) a liquid selected from dicyclopentenyl acrylate, dicyclopentenyl methacrylate, mixtures thereof, and mixtures of at least one of said (meth)acrylates with up to 40% by weight of another non-volatile monomer, such as a higher alkyl or alkenyl acrylate or methacrylate, and (c) a siccative or drier, the proportion of component (b) being such as to make the composition of workable consistency, and the amount of (c) being from 0.0005 to 2% by weight of component (b).

Abstract
This application concerns compositions comprising a mixture of air-drying dicyclopentenyl acrylate or methacrylate binder and a granular or particulate aggregate material, which may comprise a hydraulic cement, and is adapted to be formed by casting, extruding, or molding in any fashion into any desired shape and air-drying and resulting shaped article, thereby producing an integral, solid article of unitary mass and structure. The dicyclopentenyl (meth)acrylate may be used as an impregnant, polymerizable in situ, for already formed articles of porous nature, e.g., concrete, wood, pressed boards, and powdered pressed metal, such as aluminum, iron, steel, etc., to reduce the permeability at their surfaces and provides hard, continuous, hydrophobic, wear-resistant, and weather-resistant surfaces thereon.
