Bond strength of concrete contaning recycled concrete aggregates and recycled plastic aggregates

Abstract

The growing environmental concerns and proper disposal of construction and demolition waste is a challenge for construction industry. Now a days in our country Solid waste management is one of the major environmental concerns. A substantial growth in the consumption of plastic is observed all over the world in recent years . The use of demolition waste as a resource for recycling or recovery is gaining grounds in many countries. The proper selection and processing of demolition waste can be helpful in producing concrete. Production of concrete using recycled aggregate concrete has many benefits, such as, proper management of demolition waste, natural aggregates shortage is addressed, reduction in transport cost of raw materials. Recycling of plastic waste to produce new materials like concrete or mortar appears as one of the best solution for disposing of plastic waste, due to its economic and ecological advantages. Several works have been performed or are under way to evaluate the properties of cement-composites containing various types of plastic waste as aggregate, filler or fibre. This thesis aims to find the possibility of the structural usage of recycled concrete aggregates and plastic aggregates when added as an alternative or mixed in different proportion with natural aggregates. A comprehensive literature review is carried out for better understanding of mechanical properties of concrete containing recycled concrete aggregates and plastic aggregates.
