摘要

以甲基丙烯酸甲酯、醋酸乙烯酯、苯乙烯及丙烯酸丁酯為單體，製造聚合物與混凝土之複合材料，研討單體之種類、浸注聚合條件及聚合物含量等對於聚合物含浸混凝土機械以性質之影響。試驗結果顯示，以甲基丙烯酸甲酯製成立之複合材料，機械性質為最佳。製造條件混凝土試體之烘乾溫度150°C，聚合溫度的80°C為宜，其抗壓強度可達普通混凝土之四倍。丙烯酸丁酯用作可塑劑時，可賦與柔軟性。本文同時利用達西定律討論單體之浸注速率與浸注量，試驗結果與理論式相當符合。

The effects of monomers, impregnation conditions, and polymer loading on the mechanical strength of the polymer-concrete composite materials are studied. It is confirmed that methyl methacrylate is the best among the four monomers investigated. The compressive strength is nearly four times higher than that of ordinary concrete. The addition of butyl acrylate to methyl methacrylate as an internal plasticize r tends to improve the flexibility of the materials. The relation between the degree of impregnation and the modulus of elasticity is also discussed. The kinetic study reveals that the mechanism of permeation of monomer through concrete is represented by Darcy's law, and a good agreement is observed between the experimental results and the theoretical equation.
