THE PROPERTIES OF AEC EXPANDING CEMENT AND ITS APPLICATION IN CHANNEL SECOND BACK-UP LINING CONSTRUCTION

摘要

The physical properties, impermeability, cracking resistance, corrosion resistance, strength, expansion and hydration of AEC expanding cement are discussed in this paper which are based on the design requirement of channel back-up lining. The technical properties of AEC and the application prospects of self-waterproofing concrete in the channel back-up lining are proved from the basic research and realistic application.
