用0.15～5.00 mm废玻璃分别取代10％,30％,60％,100％(质量分数)天然砂和石灰石碎石来配制混凝土,测试混凝土试样300,400,600,900℃受热后的质量损失率、抗压强度和劈裂抗拉强度.结果表明:混凝土质量损失率随其受热温度的升高而增大；随着混凝土受热温度的不断升高,因混凝土内部缺陷增多和劣化不断加剧,混凝土强度不断降低；用废玻璃取代混凝土骨科有益于抑制混凝土内部的受热劣化,当废玻璃取代率为80％～100％时,对800～900℃受热混凝土的强度有较好的益化效果；废玻璃高温益化作用可以用混凝土强度保持率(P)、混凝土抗压强度保持率(Pc)-受热温度(t)回归方程斜率和废玻璃高温益化系数(δ)指标来...

Concrete was made with 0.155.00 mm waste glass replacement of natural sand and limestone crushed stone at levels of 10%, 30%, 60% and 100% (by mass). Concrete specimens were tested for their mass loss rate, compressive strength and splitting tension strength at 300, 400, 600, 900°C. The experimental results obtained show that mass loss rate increase with increase of temperature(t). Concrete internal defects and degradation are developed with temperature increases, leading to concrete strength decrease. It is found that the replacement of concrete aggregate with waste glass hindered concret...
