A Study on lignocellulosic Fiber Reinforced Concrete

Wasteful use of mineral resources in construction industry has caused mass generation of waste products. In the following research, the use of natural lignocellulosic fiber in manufacturing concrete has been studied. After choosing the fitting fibers (date tree fibers, Palm and rice), various examinations are conducted to study the function of the samples in 1.5 and 0.5 percent composition of fibers and concrete samples. Examinations used in the following study, included: concrete slump test, flexural strength, modulus of rapture and compressive strength. Laboratory results indicated that the use of rice fibers significantly improved the factors such as rapture modulus, flexural strength and cracking behavior. Eventually the rice fibers were chosen as the best option compared to the other samples (date tree fibers and palm).
