Assessment on compressive strength of Waste Rubber Tube Tyre (WRTT) fiber in concrete

摘要

The study is concentrated on assessment on compressive strength of Waste Rubber Tube Tyre (WRTT) fiber as reinforced bar replacement in concrete. WRTT fiber is produced from waste tyre industry. WRTT fiber is determined for its density and percentage of water absorption. WRTT fiber is designed and cut to a size of 5 cm in length, 0.5cm in breadth and 0.1 cm in thickness. WRTT fiber is mixed with concrete with percentage proportion of 0 %, 1 %, 1.5 %, 2.0 % and 2.5 %. All concrete are cured in clean and clear water and tested for compressive strength at 7 and 28 days. Every mixes illustrateda low compressive strength compared to a control mix. The highest percentage proportion of 1.0 % showed 40–45 % different when compared with control mix for early and matured ages. Finally, further studies can be done to assess the general issues of strength to show the potential of WRTT fiber in concrete.
