Zusammenfassung:The purpose of the present invention is to provide a concrete composition containing cellulose fibers capable of improving absorbency, strength, and concrete properties, and a method for manufacturing a permeable block using the same. The method for manufacturing a permeable block includes: a first step of selecting wood chips having a size of 6 to 40 mm from which bark has been removed; a second step of subjecting the wood chips to kraft pulping to obtain unbleached pulp; and a third step of subjecting the unbleached pulp to alkaline treatment to produce cellulose fibers. The concrete composition containing cellulose fibers of the present invention can realize excellent fiber strength, fiber absorbency, and retention. In addition, the kraft pulping bleaching process of the present invention is used to maintain an appropriate pH, the existing pH control process can be omitted, thereby increasing productivity. 본 발명은 셀룰로오스 섬유를 첨가한 콘크리트 조성물 및 이를 이용한 투수블록 제조방법에 관한 것으로, 구성된 것을 특징으로 한다.
