Abstract:
Impregnation of methyl methacrylate in hardened bridge deck type concrete was studied in 4 laboratory using a field applicable technique. Pentration as deep as 8 in. (20.3 cm) was obtained 5 ponding only. It was found that monomer loading was mainly determined by the amount and distribution of moisture in the concrete, and was slightly affected by ambient temperature. Due possiby to the disturbance of the capillary network, unequal rates of impregnation were noticed specimens dried by different methods. Simple equipment and operation processes showed satisfactory drying, impregnation, and polymerization.
