本文通过调节水胶比控制砂浆稠度,以不同比例的改性纤维素取代纤维素醚,进行了试验研究,结果表明砂浆保水率和粘结强度均随改性纤维素取代率的增加先增加后减小,砂浆抗压强度和表观密度随改性纤维素取代率增加而增加,根据抹灰和砌筑M5、M10砂浆试验最终确定改性纤维素最佳取代率范围为20%~30%。
In this paper, by adjusting the water-cement ratio to control the consistency of mortar, with different proportions of cellulose substituted cellulose ether, the experimental study showed that the mortar water retention and bond strength with the modified cellulose replacement rate increased first increased Decreases, the compressive strength and apparent density of mortar increase with the increase of modified cellulose substitution rate. According to the tests of mortar and masonry M5, M10 mortar, the optimal replacement rate of modified cellulose is 20% -30% .
