The deformation properties of MgO expansion agent-mixed cement paste under different curing conditions

This paper is concerned with the deformation properties of MgO expansion agent-mixed cement paste under different curing conditions.Results showed that with reducing of curing humidity,the effect of compensation shrinkage of cement paste containing MgO expansion agent decreased gradually.While raising the curing temperature,the effect of compensation shrinkage of cement paste containing MgO expansion agent increased,and time needed to obtain stable expansion shortened obviously.
