Research and application of using stone chips instead of sand in concrete;
石屑代砂在混凝土中的研究与应用
Because natural sand has a poor stickiness and is a limited resource,and stone chips of poor quality affect the performance of asphalt mixture,using machine-made sand in large quantities becomes inevitable.
细集料是沥青路面不可缺少的材料组成部分,由于天然砂的粘附性较差又是一种有限资源,品质较差的石屑影响沥青混合料的性能,致使机制砂的大量应用成为必然趋势。
The difference on density between crystal and glassy of cuspidine in CaO-SiO_2-CaF_2 slag and CaOSiO_2TiO_2 in CaO-SiO_2-TiO_2 slag during condensation has been studied.
研究了可析出枪晶石矿相的 CSF 渣系和析出屑石矿相的 CTS 渣系在冷凝后渣中结晶体和玻璃体密度的差异, 得到以下结论：(1)在保护渣的玻璃体向结晶体的转化过程中,出现了体积膨胀与体积收缩两种现象；(2)保护渣的结晶性能与凝固收缩情况密切相关；(3)析晶过程中保护渣的体积变化可能受晶粒大小及气孔影响。
