ABSTRACT:
Cement-resin composite articles are manufactured by preparing cement articles from Portland cement having a high silicic modulus, or a mixture of 50 to 90% by weight of Portland cement and 50 to 10% by weight of siliceous reactive material, presetting the cement articles at ambient temperature, steam curing the articles under pressure at a temperature from 150.degree. to 250.degree. C. for 1 to 6 hours, subjecting the steam cured articles to a thermal treatment in an anhydrous environment at a temperature of 120.degree.-350.degree.C. for 1 to 12 hours, impregnating the resulting articles with a monomeric polymerizable substance, and polymerizing the monomeric substance. The monomeric substance may be styrene, methylmethacrylate, vinyl ester, or a mixture of copolymerizable monomers. The articles may be placed under vacuum before impregnation and impregnation may be conducted under elevated pressure.
