Effect of waste rubber tire ash and recycled concrete fines in concrete

Session

Civil Engineering, Infrastructure and Environment

Description

Every year in the world, millions of tons of waste are produced which all the waste produces are not recyclable. The main cause for pollution is the energy consumption of recycling waste. The problem of accumulation of waste is increasing day by day and are very dangerous for the environment. Around 1000 million tires are left unused at the end of their utility period in every year. It has been expected that around 5000 million extra will be expected by the year 2030. More than 3 billion tons of construction and demolition waste (CDW) is produced annually. The main source is construction industry. This is an increasing problem day by day which cause serious land filling. As an alternative, the demolition waste can be processed and used as an aggregate in concrete and mortar. Hence, this work mainly focus on use of waste tire rubber ash as substitute of cement and using fine aggregate produced from recycled concrete fines as substitute of fine aggregates for the production of concrete. A replacement of 3% and 6% of waste tire rubber ash as cement and a partial replacement of 10% and 15% of recycled concrete fines as fine aggregate were casted and tested for its various curing periods. Mechanical properties such as compressive strength, splitting tensile strength, flexural strength tests were carried out. The obtained test results were compared and analyzed with control mix.
