增效剂与粉煤灰对水泥砂浆力学性能的影响研究

Effect of synergist and fly ash on mechanical properties of cement mortar

为了研究增效剂和粉煤灰对水泥砂浆力学性能的影响,通过单加增效剂、单加粉煤灰和两者互掺,分别研究其对水泥砂浆的抗折强度和抗压强度的影响。结果表明,单加增效剂的情况下,在掺量为0.6%的情况下,水泥砂浆的综合力学性能良好,当单掺粉煤灰时,掺量为30%时,效果最佳,当两者互掺时,增效剂掺量为0.6%和粉煤灰掺量为30%时,水泥砂浆的综合力学性能良好。

In order to study the effect of synergetic agent and fly ash on the mechanical properties of cement mortar,it studies the effect of synergetic agent,fly ash and both on the flexural strength and compressive strength of cement mortar.The results show that the comprehensive mechanical properties of cement mortar are good when the addition of synergist is only 0.6%,the best when the content of fly ash is 30%,and the best when the synergist and fly ash are 0.6%and 30%respectively.
