摘要

The present invention relates to an eco-friendly mortar for pipe repair and reinforcement and a pipe line repair and reinforcement method using the same, while minimizing the generation of hexavalent chromium (Cr ⁶⁺ ), a harmful substance, by excluding Portland cement, improving the bonding strength and strength with the reinforcing material I made it possible to do it. The eco-friendly mortar for pipe repair of the present invention, blast furnace slag cement 49-55% weight, PE bonded 0.05-0.2% weight, polymer 0.2-1.5% weight, thickener 0.02-0.1% weight, foaming agent 0.05-0.2% weight and It contains 40-50% weight of fine aggregate, wherein the PE ply is added in a uniformly dispersed form provided with short fiber PE plying yarns of 3 to 6 cm in length bent at both ends in a ring shape in order to increase bonding and tensile strength. do.
