The Environmental Impact of Recycled Concrete

2012-8-14  Abstract Concrete is a building material used worldwide and consumes large amounts of raw materials. The concrete structure is cheaper than steel structures; the raw materials can be found in almost anywhere and can be moulded easily. Nevertheless, the concrete industry produces a lot of waste and the old concrete many times goes to landfills.

Recycling of concrete construction and demolition waste

Abstract. The concrete construction and demolition waste (CDW) is usually recycled as coarse aggregate. The fine fraction remains unused ─ if recovered at all, it is for downcycling in backfilling. Part 1 of this article is dedicated to a technical study on recycling of the waste concrete powder (WCP) as supplement in blended cements.

Recycling of concrete construction and demolition waste

The concrete demolition and construction waste (CDW) is usually recycled as aggregate. The fine fraction (crushed sand and powder) obtained from the recycling process remains less recovered ─ for downcycling purposes such as backfilling, if recovered at all. The feasibility study on the recycling of concrete waste as a component of a blended binder is presented in Part 1 of the study.
