Recent Trends in Research and Development Activities of Polymer-Modified Paste, Mortar and Concrete in Japan
The present paper reviews the recent trends in the research and development activities of polymer-modified paste, mortar and concrete which have most widely been used of concrete-polymer composites in the Japanese construction industry. In Japan, the active research and development of the polymer-modified paste, mortar and concrete have been carried out for the past about 50 years, and they are currently used as dominant construction materials in various applications because of their high performance, multifunctionality and sustainability compared to conventional cement paste, mortar and concrete. The recent research and development activities of the polymer-modified paste, mortar and concrete are concerned with concrete crack repair systems, patch repair systems for deteriorated reinforced concrete structures, repair systems with concrete surface coatings, strengthening systems for existing reinforced concrete structures, adhesives for exfoliation prevention methods, liquid-applied membrane waterproofing systems, high-grade redispersible polymer powders, intelligent repair materials, and reaction to fire as repair materials in building construction.
