PROTECTING CONCRETE BY FLEXIBLE WATERPROOFING SLURRIES. PROCEEDINGS OF STRATEGIC HIGHWAY RESEARCH PROGRAM AND TRAFFIC SAFETY ON TWO CONTINENTS , GOTHENBURG, SWEDEN, 27-29 SEPTEMBER, 1989. HIGHWAY OPERATIONS. CONCRETE AND STRUCTURES

Flexible waterproofing slurries consist of sand, cement, water, an aqueous polymer dispersion, and various additives. Their polymer content is 7-9 weight %. They are applied in two to four coats of 2-4 mm total thickness onto wetted concrete. The bulk of the water evaporates, and the polymer forms a tough, rubbery film, which bridges over fine cracks and waterproofs the concrete without impeding water vapour diffusion, i.e. for drying of concrete to stop corrosion of the reinforcement. Concrete coated with flexible waterproofing slurries practically no longer carbonates, and chloride penetration is considerably supressed. Laboratory studies and many years of practical experience have demonstrated that flexible waterproofing slurries are eminently suitable for additionally or subsequently protecting concrete, e.g. on sections of road bridges exposed to spraying water and generally in the case of repair.
