摘要：This research work investigates the effect of the addition of steel and glass fibers in design mix M25 based concrete. Steel fiber having length of 30mm and diameter 0.75mm, well crimped and glass fiber length of 20mm was used. Three specimens were cast having same percentage ratio of both steel and glass fibers. Based on experimental studies, the paper identifies fibers combination demonstrate maximum flexural strength. Flexural test were performed and results were analyzed with respect to plain concrete (0% fibers). Finally, the results show that introducing fibers to concrete resulted an increase in flexural strength depending on the fibers ratio used. The use of concrete as a structural material is limited to certain extent by deficiencies like brittleness, poor tensile strength and poor resistance to impact strength, fatigue, low ductility and low durability. It is also very much limited to receive dynamic stresses caused due to explosions. The brittleness is compensated in structural member by the introduction of reinforcement (or) pre-stressing steel in the tensile zone. However it does not improve the basic property of concrete. It is merely a method of using two materials for the required performance. The main problem of low tensile strength and the requirements of high strength still remain and it is to be improved by different types of reinforcing materials. Fibers are usually used in concrete to control cracking due to plastic shrinkage and to drying shrinkage. They also reduce the permeability of concrete and thus reduce bleeding of water. Some types of fibers produce greater impact, abrasion, and shatter resistance in concrete.
