Abstract
Concrete is probably the most extensively used construction material in the world. The modern concept of construction is directed at the use of recycled materials, in particular, various waste products. This solves a number of problems -saving the expensive materials; - decreasing CO2 emissions by reducing the production of construction materials, so, these can also be used as refractory materials. Plant fibers are the most abundant fiber among all the natural fibers. Bamboo, palm, sisal, jute, date kernel, flax etc. are the commonly known plant fibers. Plant fibers are also called cellulosic fiber and have quite promising tensile strength. Natural Plant fibers treated by pyrolysis in concrete such as additions; determine the effect of these substances and the effect of temperature on the properties of concrete. The natural fibers in concrete are added accordingly with the percentage of 0.5%, 1%, 1.5% and 2% by weight of cement concrete cubes are tested at the age of 7 and 28 days of curing. Natural waste treated by pyrolysis and different additives on concrete behavior to improve its performance in the future to use in Civil Engineering and Construction World. The optimum result for natural fibers was observed at 1.0% for bamboo and date kernel and 1.5% for palm oil of natural fiber.
