用粒径1.18～5.00 mm,600 μm～1.18 mm,300～600 μm和＜300 μm这4种废玻璃分别取代(质量分数)30％,60％,100％天然砂配制砂浆,测试砂浆在20,300,400,600,800,900℃的抗压强度和劈裂抗拉强度.结果表明:在常温下,用粒径≥300 μm废玻璃取代天然砂后,砂浆强度低于基准砂浆,且随废玻璃取代率增大而降低；用粒径＜300 μm的废玻璃取代部分天然砂后,砂浆劈裂抗拉强度略大于基准砂浆,抗压强度则大大高于基准砂浆；所有配合比砂浆强度均随着加热温度的提高不断降低,强度与加热温度间呈良好的线性关系,相关系数大多＞0.980;用粒径＜300μm废玻璃取代60％以上天然砂,高温益化系数＞1.25,可显著提高砂浆...

Mortar was made with 1.18-5.00 mm, 600 μm-1.18 mm, 300-600 μm and <300 μm waste glass replacement of natural sand at levels (by mass) of 30%, 60% and 100%. Mortar specimens were tested for their compressive strength and splitting tension strength at 20, 300, 400, 600, 800 and 900°C. The experimental results show that the mortar which was made with ≥300 μm waste glass replacement of natural sand, its strengths at room temperature are lower than control mortar's and decrease with increase of temperature. The mortar which was made with <300 μm waste glass replacement o...
