RESEARCHES ON CRACK-PREVENTION TECHNIQUES OF FACE SLAB CONCRETE IN WULUWATI HIGH CONCRETE FACED SANDY GRAVEL ROCKFILL DAM

摘要

The properties of shrinkage-compensating concrete made by adding expansion agent into concrete are introduced by taking the face concrete of Wuluwati concrete face sandy gravel dam for an example. Besides, construction experiences of reducing or preventing cracking by using the properties of shrinkage compensating concrete are introduced when concrete face slabs longer than 50-105m are placed continuously.
