Jul 23, 2010 . In this study, chromite industry waste and red mud were used in the production of concrete. They were ground and incorporated into concrete with the levels of 5%, 10% and 15% by the weight of binder. Ten mixtures were prepared with different propor- tions of both the chromite industry waste and the red.

Since the production of. Portland cement is so energy intensive and responsible for CO2 generation, the substitution of other materials, especially those that are byproducts of industrial processes, such as fly ash and slag, is bound to have a major positive impact. 2. Increased reliance on recycled materials. Since aggregate.
aggregate for new concrete. Since the 1990s, other by- products have been successfully used in concrete. These materials include: used foundry sand and cupola slag from metal-casting industries; post-consumer glass; wood ash from pulp mills, sawmills, and wood-product manufacturing industries; sludge from primary.
The preparation of cement involves mining; crushing, and grinding of raw materials (princi- pally line and clay); calcining the materi- als in a rotary kiln; cooling the resulting clinker; mixing the clinker with gypsum; and milling, storing, and bagging the finished cement. The process generates a variety of wastes,.
Moreover, high-volume fly ash recycled- aggregate concrete (HVFA-RAC) can be manufactured with a water to cement ratio of 0.60, by simultaneously adding to the mixture as much fly ash as cement, and substituting the fine aggregate fraction [Corinaldesi & Moriconi 2002]. Thus, water to cementitious material (binder).
Abstract- There is now a significant world-wide interest to solve the environmental problems caused by industrial waste and other materials by including such materials in the manufacture of concrete.This technology has been introduced in India in construction, a decade ago, for specific requirement namely footpaths.
Concrete has a problem. Already pilloried through its use in countless architectural eyesores, from tower blocks to carparks, concrete's environmental credentials are also now coming under scrutiny. The material is used so widely that world cement production now contributes. 5 per cent of annual anthropogenic global CO2.

Abstract. Concrete demolition waste can be used as material for manufacturing high quality recycled coarse aggregates, which can replace natural aggregates to make hydraulic concrete mixes. In this study, the behavior of two hydraulic concrete mixes have been analyzed and tested under similar conditions.
