<p>PURPOSE:To show a quantity of abrasion not exceeding one tenth as compared with ordinary concrete not impregnated with resin, by a method wherein a concrete base is impregnated with a monomer into which a polymerization initiator is dissolved, then heated and the monomer is polymerized. CONSTITUTION:After concrete for which ceramic material is used as aggregate is hardened sufficiently, dried up to a dried condition by a fan drier and cooled down to a room temperature after that. Then the concrete base is put into a vacuum vessel and a gaseous component in the concrete base is deaerated. When the monomer in such a quantity that the whole of the concrete base in a vacuous state vessel can be immersed is cast into the vessel, the monomer is infiltrated away into a pore part of the concrete base up to the inside of the same. As for the infiltrated monomer, a radical is generated by a polymerization initiator through heating, polymerization is initiated by reacting on a double bond of the monomer and furthermore the polymerization is advanced by a chain reaction of the radical of the other monomer.</p> |
