Abstract: This application relates to a cement mortar composition reinforced with a shredded waste fishing net and a method of manufacturing the cement mortar composition. In one aspect, the cement mortar composition includes cement mortar including cement, fine aggregate, and water and 0.5 to 2.0 parts by weight of a fibrous reinforcing material based on 100 parts by weight of the cement mortar. The fibrous reinforcing material may be manufactured by shredding a knotless fishing net and being formed of a single yarn that has a length of 3 mm to 60 mm and a diameter of 0.1 mm to 1 mm. The cement mortar composition that has improved crack resistance and tensile strength and in which an environmentally friendly and inexpensive reinforcing material obtained by shredding a waste fishing net at a random length instead of existing highly-expensive reinforcing material is included may be realized.
