摘要
介绍武定门抽水站钢筋混凝土挡水墙裂缝修补方法 .采用掺入CT2 0 3型抗分散剂的聚合物砂浆 ,在标准养护条件下 ,与不掺的普通砂浆比较 ,抗压和劈拉强度接近 ,但粘结劈拉强度提高10 %左右 .根据M30设计配合比施工的聚合物砂浆 ,经测试其粘结抗折强度为 7.6MPa 。
In the crack repairing of reinforced concrete walls at Wudingmen Pump Station mortar with CT20 3 non dispersion polymers is used. In the standard maitenance condition,the compressive strength and the tensile strenth of the new mortar are almost the same as that of the ordinary mortar,but the cohesive tensile strength of the new mortar increases by 10%.According to the test,the cohesive tensile strength of the polymer mortar of M30 reaches 7 6?MPa ,over the technical requirement.
