Abstract

Abstract

Firstly, the compressive and flexural strength of mortar with chloride ion permeating in sands during mixing investigated in 3, 5, 7, 14, 28, and 90 d.It is found that chloride ion permeating in sands will not improve the mortar strength of early stage, but reduce the corresponding strength, which is obviously different from the effect of chloride ion permeating in water.Then the bond performance of above mortar in 270, 360, 450, 630, 810, 1 050, 1 170, 1 320, and 1 440 d was studied based on 4 years long-term exposure experiments.The -s slipping curve with different content of chloride ion, the time-variant maximal bonding strength, also its tensility change rule are presented.Finally, the fitting formula of -s was gained by origin software.
