AN EXPERIMENTAL INVESTIGATION OF DESIGN OF M50 CONCRETE BY USING LATHE WASTE AND DRINK CAPS AS FIBERS

B.BALA SUBRAHMANYAM

Abstract

Generally concrete is strong in compression and weak in tension. To increase tensile strength for this purpose fibers are used in concrete and increases its tensile strength, fiber reinforced concrete using waste materials is a systematic procedure. In that case designing M50 mix and the design mix is done using the Code IS 10262-2009.In that the water-cement ratio is taken as 0.4 and in this first conventional mix taken and in that there are increase an admixture content of 0.25,0.5, 0.75& 1% mix and in that the 0.5% admixture has greater strength than the remaining mixes so 0.5% admixture and 0.4% water cement ratio is taken as greater strength. And the admixture content is taken in the cement content only and these are tested for cubes, cylinder and prisms. These tests are calculated for 7days & 28daysand the greater strength ratios of admixture and water cement ratio is used for adding fibers. In this experiment BASF is used as admixture. The fibers are drinking bottle caps and lathe mission waste. In drink bottle caps first the caps are softened and then these are cutting with 3mm width and 10mm length and this is cutting in uniform length and the lathe waste also in the same dimensions. And the mixes of drink caps in 0.25%, 0.5%, 0.75%, 1%. In total volume of the mixture and this mixes of lathe waste is also same as drink caps in total volume of mixture and the strength are calculated for 7days & 28days and these strength is compare with conventional mix which is greater than that mix in this for fibers of 0.25% drink caps has maximum strength.
