Experimental research on the effect of silicon powder on the performance of cement mortar

To study the effect of the mechanical properties of silicon powder on cement admixture, the experiment was carried out, to investigate the consistency of mortar fluidity, breaking strength and compression strength test of the cement mortar samples with different dosage of silicon powder. The experimental results show that when the content of silicon powder is 0-4%, the consistency and fluidity of mortar can be improved, and the working performance of cement mortar can be improved; when the content of silicon powder continues to increase to 12%, the working performance of mortar decreases, but it still has good performance; when the content of silicon powder is 0-8%, the mechanical performance of mortar can be improved, if the content is too large, the compression strength and bending strength of mortar will be reduced, but It still plays a positive role in the strength of mortar.
