Abstract

PROBLEM TO BE SOLVED: To obtain flexibility and excellent follow-up property to external behavior by mixing a flexible resin, rubber powder and natural fiber into a mortar. SOLUTION: An acryl rubber emulsion or a SBR emulsion as a flexible resin, a rubber powder prepared by pulverizing a rubber comprising a well- known resin into <2 mm particle size, and a natural fiber such as sepiolite are mixed as well as a cement, water, aggregate and admixture as the structural elements of a mortar. Thereby, flexibility can be added, however, the amts. of the flexible resin and the rubber powder are controlled not to cause decrease in the strength of the mortar. The amt. of the fiber is controlled not to decrease flexibility to be added to the mortar. When the obtd. mortar is applied onto the surface of a concrete or used for tiling, peeling of the concrete or dropping of tiles can be prevented.
