Abstract
Concrete is the combination of cement, natural sand or artificial sand and aggregate which are used in civil engineering works such as township project and infrastructure work . The present research work shows the study of cement concrete with varying percentage of fibers which are namely 0.10%, 0.20%, 0.30% ,0.40% & 0.50%. M20 grade concrete was adopted. Sizes of cube (15*15*15 cm) were used for testing. Compressive test of cubes was carried out with different types of fibers name ly AFRC and NFRC with natural sand and artificial sand. The aim of this research is to use of different fiber as reinforcement in concrete for a greater durability, workability and reduction in crack. The present work is concerned with the compressive str ength of FRC specimens (132 cubes) with 90 days of normal water curing and 90 days curing in sulphate & chloride. The method of mixing play an important character in FRC in which stress is determined by the fiber orientation. FRC controls micro cracking a nd deformation under load much better than plain concrete. About 43.8 N/mm 2 extreme compressive strength found with N.S at 0.4% fiber concentration when cubes samples were cured in plain water (AFRC) & about 44.1 N/mm 2 extreme compressive strength found w ith natural sand at 0.4% fiber concentration when cube samples were cured in NaCl & MgSO 4 mixed water (AFRC) and about 35.8 N/mm 2 compressive strength found with artificial sand at 0.4% fiber concentration when cubes samples were cured in plain water (AFRC ) & about 39.9 N/mm 2 compressive strength found with artificial sand at 0.4% fiber concentration when cube samples were cured in NaCl & MgSO 4 mixed water (AFRC)
