摘要

研究在混凝土材料中加入聚甲基丙烯酸甲酯（PMMA），制备了高强度PMMA复合塑料混凝土材料，并探究不同PMMA掺杂量对复合塑料混凝土材料力学性能的影响。结果表明：在材料的力学性能方面，抗压强度、抗折强度、抗拉强度、弹性模量和劈裂抗拉强度均随着PMMA掺杂量的增加呈现先上升后下降的趋势，并在PMMA掺杂量为6%时达到最大值，同时各项性能也达到最优。复合混凝土材料在冻融前后以及高温的条件下也能够保持其优异的抗压强度和抗折强度，说明制备的复合混凝土材料具有良好的应用前景。

Abstract

In this study, high strength poly(methyl methacrylate) (PMMA) composite plastic concrete materials were prepared by adding PMMA to concrete materials, and the effects of different PMMA doping concentrations on the mechanical properties of composite plastic concrete materials were investigated. The results show that the compressive strength, flexural strength, tensile strength, elastic modulus and splitting tensile strength of the material firstly increase and then decrease with the increase of PMMA doping concentration. The maximum value is reached when the PMMA doping concentration is 6%, and the properties are also optimized. The composite concrete material can maintain its excellent compressive strength and flexural strength before and after freezing and thawing and under high temperature conditions, indicating that the composite concrete material prepared in this study has a good application prospect.
