改性煤渣对菱镁水泥性能影响的试验研究

Experimental study on effect of modified cinder on properties of magnesite cement

本文通过对比试验,研究了改性煤渣不同掺灰量对菱镁水泥强度、耐水性的影响。研究表明在菱镁水泥中加入改性煤渣可以显著提高强度和耐水性,在煤渣掺量为10%时,强度达到最大值,掺量超过10%时强度随掺量增加逐渐降低;在掺量为20%时,耐水性最强,掺量超过20%时,耐水性会随着掺量增大不断降低。

In this paper, the influence of different amount of modified cinder on strength and water resistance of magnesite cement was studied by comparative test. The experimental results show that adding modified cinder into magnesite cement can significantly improve the strength and water resistance. When the cinder content is 10%, the strength reaches the maximum, and the strength decreases gradually with the increase of the content. When the content is 20%, the water resistance is the strongest. If the content exceeds 20%, the water resistance will decrease with the increase of the content.
