摘 要:利用废弃玻璃等质量取代混凝土粗、细集料,通过冻融循环试验,研究玻璃混凝土的抗冻性能。冻融循环作用后,普通混凝土质量损失率大于玻璃粗集料和玻璃细集料混凝土。冻融循环作用能够引起普通混凝土和玻璃混凝土的抗压强度降低。在冻融初始阶段,普通混凝土与玻璃混凝土相比其抗压强度下降较快;随着冻融循环次数的增加,冻融循环对玻璃混凝土抗压强度的影响小于普通混凝土。研究表明玻璃混凝土具有良好的抗冻性能。The frost resistance of the glass concrete which use the waste glass to replacing coarse and fine aggregates in the same quality was researched by the freeze-thaw cycle test. After freezing and thawing cycles, the mass loss rate of the ordinary concrete is greater than that of the coarse aggregate and fine aggregate glass concrete. The freezing and thawing cycles cause compressive strength decreases of both ordinary concrete and glass concrete. In the initial stage of the freezing and thawing test, the compressive strength of the ordinary concrete decreased more rapidly than that of the glass concrete;with the increase of the numbers of freeze - thaw cycles,the effection on the concrete' s compressive strength of the glass concrete is less than that of the ordinary concrete. Studies indicate that the glass concrete performance good on frost resistance.
