建筑用砂作为一种不可缺少的建筑材料被大量使用,而将转炉渣作为替代性混凝土细骨料可以减轻对环境的破坏。经过热焖、磁选、筛分等工艺处理后制得的转炉渣砂满足《建筑用砂》的各项性能指标,符合其规定的Ⅱ类中砂要求。在配制相同强度等级(小于等于C40)的混凝土时,在同条件下早期抗压强度较山砂、河砂高约5~15%。 Building sand is widely used as an indispensable building material, and using converter slag as an alternative concrete fine aggregate can reduce the environmental damage. After heat stewing, magnetic separation, screening and other processes prepared converter slag sand to meet the “construction sand” of the performance indicators in line with its provisions of Class Ⅱ sand requirements. In the preparation of the same strength grade (less than or equal to C40) of concrete, under the same conditions earlier compressive strength than mountain sand, river sand about 5 to 15%.
