Studies have been made by various researchers in the attempt to improve the brittleness of cement mortar by admixing polymer emulsion or fibers independently, but the method to admix both polymer emulsion and fiber has not yet been developed This experiment is based upon the inference that there would be multiple effects by admixing the three components, polymer emulsion, fibers and cement in what is termed a three component system. This was proven by the experiment. In the study of the three component system conducted by the authors, it was found first of all that the sorrounding fibers were remarkably improved in bonding strength with simultaneous improvement in the equilibrium condition of the elasticity between the fibers and the matrices sorrounding the fibers. consequently the stress distribution of the fibers was remarkably improved. According to these effects, it made it possible for the tensile strength of the fibers to contribute to fully serving the purpose of reinforcement. This experiment suggested one more important way in the improvement of brittleness in hardened cement materials. The present study, while it deals with some fundamental problems in the polymer emulsion-fiber-cement system, aims at its fruition extensively in possible application in the industrial field, giving new outlooks to the studies in this direction.
