研究了潮湿环境下纤维素醚对高强修补砂浆的工作性能及物理力学性能的影响。结果表明:纤维素醚的掺量、种类对高强修补砂浆拌合物的稠度有一定的影响;高强修补砂浆拌合物的稠度随着纤维素醚掺量的增大而减少,随着纤维素醚粘度的增大而降低。潮湿的水养护环境下,纤维素醚的掺量、种类对高强修补砂浆的强度有影响,高强修补砂浆的抗压、抗折强度随着纤维素醚掺量的增大而降低;潮湿的水养护环境下,低掺量的范围内,纤维素醚的掺量对高强修补砂浆28d的压折比影响相对较小,但当掺量达到0.12%以后则高强修补砂浆的压折比会有所降低,柔韧性有所增强。
The effect of cellulose ether on the working performance and physical and mechanical properties of high-strength mortar under wet conditions was studied. The results showed that the content and type of cellulose ether had a certain influence on the consistency of high-strength repair mortar mixture. The consistency of high-strength repair mortar mixture decreased with the increase of cellulose ether content. With the increase of cellulose Ether viscosity increases and decreases. Under the condition of moist water conservation, the content and type of cellulose ether have an impact on the strength of high-strength repair mortar. The compressive strength and flexural strength of high-strength repair mortar decrease with the increase of cellulose ether dosage; Within the range of low dosage, the content of cellulose ethers has a relatively small effect on the crimp ratio of high-strength mortar for 28 days, but when the dosage is 0.12%, the crimp ratio of high-strength mortar will be higher Reduce the flexibility has been enhanced.
