Continuous evolution of automotive sector results in massive congregation of waste rubber fiber. The disposal of waste RF in sustainable means has become a serious issue worldwide. The application of RF into construction industry as a substitute to natural resources gives a promising method to solve the issue. This study thus preliminary investigates the potential application of waste rubber fiber (RF) for the development of self compacting concrete (SCC).

摘要

Continuous evolution of automotive sector results in massive congregation of waste rubber fiber. The disposal of waste RF in sustainable means has become a serious issue worldwide. The application of RF into construction industry as a substitute to natural resources gives a promising method to solve the issue. This study thus preliminary investigates the potential application of waste rubber fiber (RF) for the development of self compacting concrete (SCC). RF was substituted with fine aggregate by volume at an increment level of 5% up to 20%. Fresh, mechanical, and durability tests were conducted to assess the performance of rubber modified SCC. Testing outcomes showed that workability decreased with the increase in RF quantity. Significant blockage was seen on incorporating RF beyond 10%. However, SCC incorporating up to 10% RF exhibited the satisfactory fresh properties confirming with EFNARC (European federation of specialist construction chemicals and concrete systems) guidelines. Compressive strength and resistance to water ingress were reduced with the increase in RF quantity. However, flexural strength was found to improve with the raise in RF quantity. The study showed that up to 10% RF can be satisfactorily employed in sustainable manufacturing of SCC without substantially affecting its properties.
