An Experimental Study on Plastic Shrinkage of fiber and Expansive Additive for Face Slab Concrete

The effects of substituting cement with fiber addition(poly vinyl alcohol), fly ash and Expansive Additive on the control of microcrack and enhanced durability performance of face slab concrete in concrete-faced rockfill dam was studied experimentally The laboratory test results shown that the mixture of fiber containing concrete and of fly ash replacement of concrete to be more effective than expansive additive concrete in the crack control and mechanical performance.
