Construction materials are increasingly judged by their ecological characteristics. Concrete recycling gains importance because it protects natural resources and eliminates the need for disposal by using the readily available concrete as an aggregate source for new concrete or other applications. According to a 2004 FHWA study, 38 states recycle concrete as an aggregate base; 11 recycle it into new portland cement concrete. The states that do use recycled concrete aggregate (RCA) in new concrete report that concrete with RCA performs equal to concrete with natural aggregates. Most agencies specify using the material directly in the project that is being reconstructed.
Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. Aggregate processing consists of crushing, screening, and washing the aggregate to obtain proper cleanliness and gradation. If necessary, a benefaction process such as jigging or heavy media separation can be used to upgrade the quality.
Concrete is a mixture of two components: aggregates and paste. The paste, comprised of cement and water, binds the aggregates (usually sand and gravel or crushed stone) into a rocklike mass as the paste hardens because of the chemical reaction of the cement and water. Supplementary cementitious materials and chemical admixtures may also be included in the paste.Our effective rock crusher could be applied to series of construction companies. For instance, the cement factories and building companies would need to use it to accomplish completed tasks. It enable the customers to earn more profits since the energy consumption is reduced. During the researching and manufacturing, Fote Machinery believe that we should connect our designs with the market demand.
The leading products of Fote Machinery includecircular vibrating screen, cow dung dryer, jaw crushing machine and so on. Moreover, we can provide program design, process flow design, standard and non-standard design for clients.

वो जो हँसते हुए दिखते है न लोग
अक्सर वो कुछ तन्हा से होते है
पराये अहसासों को लफ़्ज देतें है
खुद के दर्द पर खामोश रहते है
जो पोछतें दूसरे के आँसू अक्सर
खुद अँधेरे में तकिये को भिगोते है
वो जो हँसते हुए दिखते है लोग
अक्सर वो कुछ तन्हा से होते है
