Eco-Friendly Concrete: A Review

Abstract

In the last decades, the use of residue in civil construction, especially in addition to concrete has been studied by many researches related to, besides to reduce the environmental polluter’s factors. This may lead several improvements of the concrete properties. In recent years increasing attention towards utilizing less energy intensive materials, such as fly ash, rice-husk ash, condensed silica fume and slag, in combination with cement to achieve energy saving. Within the concrete industry, the most successful examples have been using coal fly ash to make high quality, durable concrete and recycling old, demolished concrete as aggregate for new concrete. From last few decades, other byproducts have been successfully used in concrete. These materials include: used foundry sand and slag from metal-casting industries; post-consumer glass; wood ash from pulp mills, sawmills, and wood-product manufacturing industries; sludge from primary clarifiers at pulp and paper mills; and de-inking solids from paper-recycling companies. This paper emphasizes on the use of industrial waste/by product which will give new dimension in concrete mix design and if applied on large scale would revolutionize the construction industry by economizing the construction cost and enable us to conserve natural resources.
