粉煤灰及矿渣对硬化水泥石干缩变形的影响

The Impact of Fly Ash and Slag on the Shrinkage Deformation of the Hardening Cement in the Dry Environment

在干燥环境下,研究了粉煤灰、矿渣及两者共同作用对硬化水泥石干缩变形的影响,结果表明:随着粉煤灰掺量的增加,干缩变形减小;随着矿渣掺量的增加,干缩变形增大;两者相互作用则可以抵消彼此对硬化水泥石干缩率增大或减小的作用.同时对产生这些现象的原因进行了分析.

This paper studies the impact of fly ash and slag and their combined effect on shrinkage deformation of hardened cement under the dry conditions.The results show that the shrinkage reduces with the increase of fly ash content and increases with the increase of slag content,and the interaction between the two can offset mutual influences.Finally the paper analyzes the causes for these phenomena.
