摘要
The present invention relates to a cement composition comprising 9 to 20% by weight of cement; 5 to 10% by weight of water; 30 to 35% by weight of fine aggregate; 30 to 44.6% by weight of coarse aggregate; 7 ~ 17 wt% of recycled coarse aggregate; Blast furnace slag powder 4 to 7% by weight; 0.1 to 0.5 parts by volume of PVA (Poly Vinyl Alcohol) fiber when the total volume is 100; The present invention further provides a steel fiber and PVA fiber reinforced concrete composition, a method of manufacturing the same, and a repair method of a concrete structure using the steel fiber and the PVA fiber reinforced concrete composition, wherein the weight of the steel fiber and the PVA fiber reinforced concrete composition is reduced, To improve the stability and durability of the structure by increasing the toughness, increasing the toughness, increasing the resistance and durability against impact, wear and fatigue, Thereby enhancing usability.
