Title: Effects of Surface Treating Methods for Concrete Cracks on Waterproof Properties
Author(s): Pei Huang, Miao Wu and Chunxiang Qian
Publication: China Concrete and Cement Products
Issue: No.4 2010(Total 174)
Appears on pages(s): 58-61
Keywords: Crack, Permeability, Repairing, Waterproof durability
Abstract:Short and long waterproof effects of cementitious material cracks after dealing with waterproof coiled materials,waterproof coatings and cement-based capillary crystalline are studied,and the waterproof durability under freeze-thaw cycles and alternation of drying and wetting is analyzed and compared.The results show that waterproof coiled materials are suitable for dealing with cracks in water surface ,and in freeze-thaw cycles and circulation of wetting and drying,they can easily have part or total debonding phenomena,which make the waterproof failure.Waterproof durability of repairing cracks of waterproof coiled materials depends on the durability of bonding layer.Waterproof coatings are suitable for dealing with cracks in water surface,which combine with cementitious materials well and not break off.Waterproof durability has also good performance in freeze-thaw cycles and circulation of wetting and drying.Even the circles increase,the waterproof failure is a gradual process.Repairing materials of cement-based capillary crystalline are suitable for dealing with cracks in water surface.Through curing process,they can play a good role in waterproof.Under freeze-thaw cycles and circulation of wetting and drying,the repairing materials of cement-based capillary crystalline have very good waterproof durability.While the circles increase,the waterproof capacity has not decreased,and the repairing materials have the performances of permanent waterproof and dynamic waterproof.
