| Abstract: | 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. |
