含泥量对混凝土强度的影响

Effect of the Activator on the Strength of the Concrete of Phosphorus Slag

研究了石子和砂子的含泥量对混凝土强度的影响。试验表明，混凝土强度随着砂、石含泥量的增大而降低。碎石中石粉含量对混凝土强度影响不大，石粉含量在一定的范围内（0～2％），混凝土强度甚至略有提高。

Here is a research on the effect of stones and mud content in sand on the strength of concrete. It is indicated through test that the strength of concrete is deduced as the mud content in sand and stones in increase and the amount of stone dust in broken stones has little effect on the strength of concrete. If the amount of stone dust can be controlled in a certain range（0-2 % ）,the strength of concrete can even be increased slightly.
