PERFORMANCE OF CONCRETE WITH WASTE PAPER, STEEL FIBER,& CARBON FIBER. To increase the awareness of the use of natural and waste fibers as construction materials in the construction industry.

      Аннотация: The compressive, tensile, and flexural performance of reinforced concrete structures is investigated with the inclusion of waste paper, steel fibers, and carbon fibers. The mass content of the additives used is 10%, 15%, and 20% of the total mix proportion. Twenty-seven cubes were tested under uniaxial compression and nine beams are tested under four-point bending. Also, 27 cylinders are tested for determination of tensile strength. The size of the cubes considered is 150 x 150 mm. Test results for all three additives for axial compressive strength, tensile strength, and ultimate strain of concrete significantly, will be presented in this project with a detailed study of the material flexural behavior. In flexure, the fibers increase the lateral load-bearing capacity and the deflection several times larger than the concrete cubes. In flexure, fiber inclusion can affect the failure mode of the composite structure significantly. This experimental investigation is carried out under mix proportions i.e. M20 and the results of the durability tests are compared with the same mix proportionated concrete cubes. The beams for flexure are made of Papercrete, steel and carbon fiber.
