Industrial wastes are often used as aggregate in concrete production to lower their production cost Large quantities of tiles are discarded during the tile production in the ceramic factories due to substandard and low quality production The tile waste can reach up to 7% of the total tile production in the ceramic tile sector
AbstractExtractive and mining operations are one of the largest waste producing streams in the world In general, mining operation is accompanied with the production of stone and slurry wast Such wastes occupy large land near the mining area and the fine slurry particles cause bronchial, vision and skin disorders in the nearby inhabitants
The most common use for Portland cement is in the production of concrete Concrete is a composite material consisting of aggregate (gravel and sand), cement, and waterAs a construction material, concrete can be cast in almost any shape desired, and once hardened, can become a structural (load bearing) element

Partial Replacement of Fine Aggregates by Rubber in Concrete , production of concrete has always lead to massive exploitation of natural resourc Manufacturing 1 tonne of Portland cement requires quarrying 15 tonnes of limestone and clay (Civil and Marine, 2007) Moreover, continuous extraction of natural
Precast concrete is made in a factory, where a dedicated batch plant produces a specially designed concrete for precast products such as structural beams, columns and double tees, architectural cladding, and wall systems

Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a lime-based cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate cement

these aggregates, and hardened concrete properties were de-termined According to the results obtained, limestone was found to be suitable for use as coarse and fine aggregate in normal-strength concrete production But, the quality of con-cretes made using the limestone aggregates were found to be dependent on the silica ratio present in them
Concrete, for example, accounts for up to 67 percent, by weight, of construction and demolition waste in the US Yet only about 5 percent is currently recycled (2)
it was intended to evaluate the effect of aggregates substitution by different wastes in the concrete production Wastes from local industries (biomass fly ashes and lime sludge) were used for replacing 50 and of the natural fine aggregat
The majority of abandoned limestone powder wastes (LPW) and wood sawdust wastes (WSW) is accumulated from the , forms of concrete production For instance, the use of waste rubber, glass powder and paper waste sludge in concrete mix has received conscribe attention over the past

Concrete is a hardened building material created by combining a chemically inert mineral aggregate (usually sand, gravel, or crushed stone), a binder (natural or synthetic cement), chemical additives, and water
Portland cement is the basic ingredient of concrete Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients Common .
Crushed Stone Aggregates Concrete Concrete is a composite construction material, composed of cement, aggregate (generally a coarse aggregate made from crushed rocks such as limestone.
In 2008, Missouri ranked 4th in the nation for limestone production (United States Geological Survey Minerals Information) From 1919 to 2008, 31 billion short tons of limestone with a present value of $175 billion have been mined in Missouri
wastes were accumulated in wide areas that have a potential for new quarries thus hinder the sustainable development in the quarry areas This study presents efforts undertaken in Egypt as well as other stone producing countries with an aim to adopt new ideas of re-using these wastes in the production of green concrete
