Properties of Recycled Aggregate Concrete Reinforced with Polypropylene Fibre
Building Department, Faculty Architecture Planning and Surveying, UiTM Seri Iskandar Campus, UiTM Perak Darul Ridzuan
This research work is aimed to investigate how the addition of various proportion of polypropylene fibre affects the mechanical strength and permeability characteristics of recycled aggregate concrete (RAC) which has been produced with treated coarse recycled concrete aggregate (RCA). Further research on RAC properties and their applications is of great importance as the scarcity of virgin aggregate sources in close proximity to major urban centers is becoming a worldwide problem. In this study, the hardened RAC properties at the curing age of 7 and 28 days such as compressive strength, flexural strength, ultrasonic pulse velocity (UPV), water absorption and total porosity were evaluated and compare with control specimens. Experimental result indicates that although the inclusion of the treated coarse RCA can enhance the mechanical strength and permeability properties of RAC, Further modification by addition of polypropylene fibre can optimize the results.
Key words: Mechanical strength / permeability / Polypropylene fibre / recycled aggregate concrete / treated coarse RCA
