FRP is now enormously used and recycling as cementitious materials is paid attention. The purpose of this paper is revealing fundamental flexural properties of cementitious composites including FRP powder. 

Cementitious composites including FRP powder that was mainly composed of unsaturated-polyester resin, CaC03 (filler of FRP) and GF (reinforcement of FRP) were investigated. The grain size of FRP powder is similar to A3 silica sand. These suggest FRP powder to use as a substitute of A3 silica sand to extrudable composite.

Heretofore, the most commonly used method of repairing cracks in concrete was by injection of a cement slurry grout. It is obvious that such a grout, based on a cementitious composition, would shrink and not fill the void completely. it is also highly likely that such a grout, after curing, v/ould crack again at the same stress points. 

The emulsions which are generally utilized in cementitious compositions are of the oil-in-water type, having at least 50% water in the composition, although some have less than 50% water, and are still... 

This latest approach of preparing the emulsion on job site eliminates these problems. Upon preparing the emulsions in the field, and blending, the blend is already in the process of polymerization, and there is no time for phase separation, especially, since the blend is added to a cementitious composition in the same way that a previously described latex is added.
