polymer-concrete composition affiliated with urethane

The present invention relates to a urethane-based polymer concrete composition, when more detailed description is not in the construction to require a waterproof and water-tightness is superior requires the construction of separate waterproof layer, prevent to prevent bleeding excitation is generated on the surface may, neutralization of the concrete layer which can be installed at the primer, it is possible to prevent oxidation of gangsangpan relates to a urethane-based polymer concrete compositions that can improve the resistance to cracking.
