This paper reviews the literature available on utilisation of waste materials in concrete and its effect on the strength and behaviour of concrete. Considering the effect of over-exploitation of natural sand from river beds for ever increasing concrete production, alternatives to natural sand are being explored. One such alternative discussed in this paper is shredded/pulverised recycled plastic waste which has been used as a partial replacement for natural sand (replacements up to 20-40 % by volume). The option of partially replacing ordinary Portland cement with ground granulated blast furnace slag is also explored. Concrete produced with plastic waste is expected to give lower values of 28-days characteristic strength and at the same time there can be questions regarding its long term durability and behaviour during fire. This paper explores various tests that can be performed to determine long term durability, chloride ingress resistance and fire performance.
