Cement mortar composition reinforced with shredded waste fishing net and method of manufacturing same

A method of manufacturing a cement mortar composition reinforced with a shredded waste fishing net, the method comprising:

• (a) collecting a waste knotless fishing net and washing off impurities on the waste knotless fishing net;
• (b) drying the washed waste knotless fishing net;
• (c) manufacturing a fibrous reinforcing material formed of a single yarn having a length of 3 mm to 60 mm and a diameter of 0.1 mm to 1 mm by shredding the dried waste knotless fishing net;
• (d) dry-mixing cement, fine aggregate, and an admixture;
• (e) mixing by adding water into a dry mixture that is obtained from the dry-mixing (d);
• (f) mixing by adding the fibrous reinforcing material into a cement mortar that is obtained from the mixing (e);
• and
• (g) manufacturing a cement mortar composition by further adding the fibrous reinforcing material into the cement mortar that is obtained from the mixing (f) and includes the fibrous reinforcing material so that the cement mortar composition including 0.5 to 2.0 parts by weight of the fibrous reinforcing material based on 100 parts by weight of the cement mortar is manufactured.
