摘要：
A concrete structural member of improved stability is produced by preparing a concrete composite layer 5 having a concrete layer 2 on one side and an aggregate layer 4 on the other side thereof, impregnating the composite layer 5 with a monomer, thermal-catalytic treatment the monomer-impregnated composite layer 5 thereby polymerizing the monomer embedded in the composite layer 5, and thereafter placing fresh concrete 7 on the aggregate layer 4' side of the polymer-impregnated composite layer 6.
