摘要
文中选择砂石骨料石粉作为原材料,对砂石骨料石粉含量对混凝土工作性能、耐久性及力学性能影响进行了研究。检测结果表明,水泥砂浆的流动度随石粉含量的增加而降低,混凝土的干缩率随石粉含量的增加而增大,混凝土抗压强度随石粉含量的增加而升高。
In the article,sand and gravel aggregate powder was selected as the raw material to study the influence of sand and gravel aggregate powder content on the workability,durability,and mechanical properties of concrete.The test results indicate that the fluidity of cement mortar decreases with the increase of stone powder content,the dry shrinkage rate of concrete increases with the increase of stone powder content,and the compressive strength of concrete increases with the increase of stone powder content.
