Abstract
Curable polymer concrete compositions suitable for articles of construction comprise (1) a minor amount of a vinyl ester resin composition, (2) a major amount of an aggregate blend comprising (a) sand and (b) fly ash and (3) a free-radical curing agent.
Claims20
A curable polymer concrete composition, suitable for articles of construction, comprising
- (1) from about 3% to about 15% by weight of a vinyl ester composition prepared by esterifying an epoxy resin containing at least one vicinal-epoxy group in the molecule with an ethylenically unsaturated carboxylic acid,
- (2) from about 85% to about 97% by weight of an aggregate composition comprising
- (a) from about 50% to about 95% by weight of sand,
- (b) from about 5% to about 50% by weight of fly ash, and
- (3) a free-radical initiator.
