Abstract
The abbreviation CPC may stand either for concrete-polymer composite, for concrete-plastics composite, or for concrete-polymer combination, like WPC which may stand either for wood-polymer composite, or for wood-plastics combination, as the present author chooses to use for convenience.
CPC is a composite material developed for the purpose of improving the properties of concrete and mortar and is generally prepared from vinyl-type monomers impregnated in concrete or mortar used as base materials, by their polymerization either by heat or by radiation.
In the experiment reported in this paper CPC has been prepared by heat polymerization of methyl methacrylate monomer (With addition of benzoyl peroxide as catalyst) impregnated in dried mortar, and its various properties, such as its strength, waterproof virtue, heat resistance, chemical resistance, are tested and discussed. In this case, the polymer loading (Percent) of CPC for testing is 13±0.5% by weight of the untreated mortar.
The conclusion obtained from these experiments is summarized as follows
(1) CPC has a structure that many voids in mortar used are filled by polymethyl methacrylate, and the polymer is incorporated into the mortar perfectly, so that its properties for example strength, water proofing property, chemical resistance, etc. are excellent compared with those of mortar as the base material.
(2) The heat resistance and resistance to boiling water at 100°C, of CPC, are good, regardless of containing the polymer as a constituent.
