摘要
研究了掺MgO膨胀剂水泥浆体在不同养护制度下的变形特性。结果表明,随着养护湿度的降低,MgO膨胀剂对水泥浆体的收缩补偿效果逐渐下降;提高养护温度,MgO膨胀剂对水泥浆体的收缩补偿增大,膨胀稳定所需时间缩短。
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.
