Line Wastes For Production Of Concrete

Waste Materials Used in Concrete Manufacturing

Silica fume (SF) is an industrial byproduct mainly from ferrosilicon producing companies. Condensed silica fume is a very fine, amorphous, and reactive mineral admixture. It reacts readily with the calcium hydroxide, which is produced during Portland cement hydration.

Use of ceramic wastes as aggregates in concrete

However, it has been estimated that the concrete industry needs 1.5 billion tons of cement, 10–20 billion tons of aggregates, and about 1 billion tons of water for concrete production purposes per year [3,4]. Moreover, it is observed that the annual consumption of concrete reaches more than 10 billion tons in modern industrial society [5,6].

Properties of concrete incorporating fine recycled

2016-6-1  Fine recycled aggregates produced by crushing concrete wastes can be used as a replacement for fine natural aggregates for manufacturing concrete. Two methods were adopted for production of fine recycled aggregates from crushed concrete wastes: first, produces coarse as well as fine aggregates (R1); second, produces only fine aggregate (R2).

Recycling of wastes for value-added applications in

2018-11-1  2.1. Recycled concrete waste. Recycled concrete is a waste material mainly obtained from construction and demolition (C&D) activities. The European Union (EU) produces about 850 million tons of C&D waste each year, representing 31% of the total waste generated within the EU (Fischer and Werge, 2009).The massive amount of C&D waste is usually used for low-value applications such as

A Review on the Usage of Ceramic Wastes in Concrete

Construction and Demolition (C&D) wastes contribute the highest percentage of wastes worldwide (75%). Furthermore, ceramic materials contribute the highest percentage of wastes within the C&D wastes (54%). The current option for disposal of ceramic wastes is landfill. This is due to unavailability of standards, avoidance of risk, lack of knowledge and experience in using ceramic wastes in
