摘　　要：改变葡萄糖-膨润土掺量,研究其对复合砂浆相关力学性能的影响。试验结果表明:增加葡萄糖-膨润土掺量,会增大复合砂浆保水率;复合砂浆抗压、抗折强度随葡萄糖-膨润土掺量的增加先上升后下降;增加葡萄糖-膨润土掺量,复合砂浆韧性先增加后减小;增加养护龄期,增大复合砂浆抗压、抗折强度,减小韧性。The influence of the content of glucose bentonite on the mechanical properties of composite mortar was studied.The results show that increasing the content of glucose bentonite can increase the water retention rate of composite mortar.The compressive strength and flexural strength of composite mortar first increase and then decrease with the increase of the content of glucose bentonite.Increasing the content of glucose bentonite can increase the toughness of composite mortar first and then decrease.Increasing the curing age can increase the compressive strength and flexural strength of composite mortar and reduce the toughness.
