The Mechanical Properties Study of Waste Bakelite Aggregate Concrete

Abstract:

This paper focuses on industrial thermosetting plastic waste reduction by recycling as the material for natural coarse aggregate replacement in concrete. This substitution of aggregate is an integration approach to preserve the natural resources and environment as well as develop the alternative recycled aggregate material to meet 3R principle and sustainable development. Bakelite waste is prohibited from disposing of sanitary landfill and direct burning because of hazardous disposal and emission reasons .There are many studies of plastic aggregate to substitute natural coarse aggregate especially PET and PE aggregate. However, there is no study of Waste Bakelite Aggregate (WBA) mixed in concrete in Thailand. This study aim is investigating the mechanical properties of Waste Bakelite Aggregate Concrete (WBAC) compare to conventional concrete (CC).The methodology is based on an experimental program by testing of concrete specimens. The data obtained from sample test according to BS standard. These test results present compressive strength of all samples both CC and WBAC. The relationship charts between mechanical properties and the waste Bakelite aggregate replacement percentage will be illustrated including the compressive strength predictable equation model. Furthermore, the chemical extraction test of waste Bakelite aggregate concrete and the durability of WBAC are notified for the utilization. WBAC is an alternative material that can be applied to the non-structural concrete product to replace the natural aggregate and helpful in waste plastic pollution mitigation.
