The present invention relates to an environmentally friendly mortar repair material and a concrete cross-section repair method using the same, while contributing to the reduction of wastes due to resource recycling while reducing toxicity caused by the use of cement and exerting air purification functions. The mortar repair material of the present invention is 34-40% by weight of one type of cement, 40-49% by weight of silica sand, 8-10% by weight of fly ash, 1% by weight of water-soluble epoxy, 1-2% by weight of purifying agent, and 1-% oil palm fiber It is composed of a composition of 4% by weight, 2 to 4% by weight of expansion cement, 3% by weight of polymer, and 0.2% by weight of thickener. The oil palm fiber is composed of short fibers of 20 to 30 mm length, and the starch is removed from the oil palm fiber. After removal, the pores are formed, and then, through a drying process, a liquid substance is allowed to penetrate, and the purifying agent is mixed by spraying phytoncide oil into a photocatalytic diluent in a state converted into an ultra-fine photocatalytic mist, and then liquefied. It is made of, and the liquid purifier made in this way is characterized in that it is added in a state impregnated with the oil palm fiber. |
