Experimental Study on Recycled Concrete Using PP Fiber
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 5
Abstract
In this thesis we have discuss about the use of Recycled Aggregate (RA) in the concrete and the effects on its Compressive Strength and Split Tensile Strength by progressively replacing the natural aggregate (NA) with recycled aggregate. The recycled aggregate will be collected from the demolished buildings and it is partially replaced by natural aggregates with various proportions of 0%, 15%, 25% and 35%. The concrete is designed for M 20 grade, the ratio is 1:1.46:3.25 with water cement ratio 0.5 from mix design (IS 10262). To improve the tensile strength in recycled aggregate concrete polypropylene fiber is used. The size and proportion of polypropylenes fiber is kept constant for the entire ratio as 6 mm and 15 % by volume of cement.The material test of cement, coarse aggregate and recycled aggregate is performed as per IS code. To check the workability of the concrete slump cone test is performed for all the ratios. To analyze the hardened concrete, compression strength test and tensile strength test are performed at 7th day, 14th day and 28th day with curing. The size of mould used is 150 x 150 x 150 mm and 300 x 150mm for compression and tensile strength respectively.
