Abstract

The importance of creating infrastructure using processes which are environmentally responsible and sustainable and that can help make full use of available resources throughout that project’s life-cycle is of great essence in today’s times. It’s estimated that millions of rubber tyres are discarded which acts as a landfill and takes up acres of useful land in the process. Here we aimed to tackle this problem and find an alternative which is eco-friendly and which can be used in any con- struction activity by coming up with an idea to use shredded rubber tyres in a mix of concrete with addition of 0.5-1% of nano-silica to enhance the strength of the mix leading to be a cost-effective material. The Slump Test for workability and a Compression Test was performed on the innovative mix of shredded rubber, nano-silica crystals, cement (M20) and other cementitious material. Various combinations such as 5%, 10%,15% and 20% of the shredded rubber tyres were mixed with 25% of cementitious material and 0.5% of nano-silica in batches over a span of 7,14,28 days and their strengths were analyzed. The various percentages of shredded rubber tyre used in the mix had different results. The trails of 5% and 10% of shredded rubber tyre were used to yield enough strength to be at par with the stand- ard requirement while the 15% replacement yielded the same strength as that of conventional concrete. The cost estimation analysis of this experiment makes the alternative mix viable if purchased in a bulk quantity. The amalgamation of two highly different materials such as nano-silica and shredded rubber tyres can create a sustainable and environmentally responsible alternative which can bring in many such more innovative and eco-friendly replacements in the construction industry.
