LEE PYOUNG WOEN

The present invention relates to an eco-friendly mortar composition for repairing a section and a method for repairing a section using the same. According to the present invention, the eco-friendly mortar composition includes: 100 parts by weight of cement; 10-30 parts by weight of seaweed; 10-40 parts by weight of calcium sulfoaluminate; 3-8 parts by weight of silica fume; 5-30 parts by weight of metakaolin; 5-20 parts by weight of methyl methacrylate; 10-60 parts by weight of fly ash; 1-10 parts by weight of polyvinyl alcohol; 5-30 parts by weight of a hardener; 5-20 parts by weight of fiber; 10-40 parts by weight of nano-ceramic particles; 5-15 parts by weight of humectant; 1-10 parts by weight of an adhesion enhancer; and 0.01-10 parts by weight of a superplasticizer. According to the present invention, the eco-friendly mortar composition can improve working environments and reduce environmental pollution. In addition, the eco-friendly mortar composition has rigidity same as or greater than that of existing cement, and can be easily applied to a place requiring rapid curing performance by being rapidly cured, at the same time.
