Alibaba.com offers 24,353 aggregate products. About 30% of these are crusher, 6% are concrete batching plant, and 2% are gravel & crushed stone. A wide variety of aggregate options are available to you, such as gravel & crushed stone, sand, and other natural stone.
The quality of RCA is influenced by the processing method and quality of original concrete. The general character of RCA, RCA and TR A 0006-2000(concrete using recycled aggregate) are introduced. The execution of RAC work, examples of real constructions with RAC, recycling of concrete powder originated from production of RAC and barriers of using RAC are discussed.
Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.

Recycled Plastic Concrete Concrete is not the most environmentally friendly material, so any innovation to mitigate its impact is welcome. Architect and engineer Henry Miller has developed a process to make concrete using two-thirds granulated plastic, which it is as strong as conventional concrete.

Abstract. The extensive, but fragmented research on recycled concrete aggregates and recycled aggregate concrete, which has been carried out in various parts of the world from 1945 to 1985, has been collated to form a comprehensive state-of-the-art document.
Oct 05, 2003· This study is conducted (1) to examine the influence of recycled aggregate on interfacial transition zone (ITZ), strength, chloride penetration, and carbonation of concrete, and (2) to propose a method for improving strength, chloride penetration, and carbonation resistances of concrete using recycled aggregates.
recycled fine aggregate and recycled coarse aggregate. It also compares these properties with natural aggregates. Basic changes in all aggregate properties were determined and their effects on concreting work were discussed at length. Similarly the properties of recycled aggregate concrete were also determined and explained here.

For these reasons, he considers RE-CON ZerØ EVO as the keystone to improve the sustainability of concrete in Japan. With his technical team, he developed an innovative concrete, ECON ®, based on aggregates produced from returned concrete admixed with RE-CON ZERØ EVO. This new concrete is now produced at the new batching plant in Nagaoka ...
Aggregates are also used in agriculture, manufacturing, and other industries. An indispensable ingredient . Aggregates are an indispensable ingredient in ready-mix concrete, asphalt, and mortar. Accounting for approximately 60% to 75% of ready-mix concrete's volume, aggregates strongly influence concrete's freshly mixed and hardened properties.
