Waste and Recycled Materials in Concrete Technology
Jan 01, 1983 This chapter reviews the waste and recycled materials in concrete technology. Concrete made with Portland cement, water, admixtures, and aggregates comprises in quantity the largest of all man-made materials. Worldwide consumption of concrete amounts to more than 1000 kg per person. The demand is expected to increase in future.

Waste Materials in Concrete Technology: Sustainability and
the use of by-products and recyclable materials in concrete can be optimized. Fresh concrete behaviour during placing is also discussed. Moreover, when using recycled materials appropriately, some important properties of the hardened concrete such as ductility and durability can be better engineered, as this paper explains and emphasizes.
