Introduction Concrete material is widely used in many engineering fields, such as construction project, traffic engineering and bridge.
Material properties of concrete are greatly improved and load bearing conditions are more complex [1].
The specimen is made using plain concrete material and three-point bending experiment is used.

The main material and reagents of the experiment was: waterborne polyurethane (PU), butyl acrylate (BA), Methyl methacrylate(MMA), Acrylic acid (AA), Sodium dodecyl sulfate (SDS) , Potassium persulfate (KPS), Sodium bicarbonate (NaHCO3) , Rosin , deionized water .The reference chemical reaction mechanism was below: C=C Addition  1) MMA +BA C-R3-COOR4-C=C (PA) O=C=N-R1-N=C=O + C=C-R2-OH C=C-R5-R1-NH-COOCO-R2-C=C 2) PU + Vinyl monomers  C=C Copolymerization (Alkenyl capped PU) 3) PA + PU PUA　(Alkenyl polymerize PUA) Results and Discussion A.
In order to understand the morphology of the latex particles, the Malvern particle size analysis for the PU raw materials and PUA composite emulsion was used, the results were shown in Fig. 2.
