PORTLAND CEMENT CONCRETE RECYCLING Portland cement concrete (PCC) recycling is the form of recycling addressed in this report. A definition proposed by FHW A and NCH RP is as follows (1): Portland cement concrete pavement recycling: a process by which an existing portland cement concrete pavement is processed into aggregate and sand sizes, then ...
Concrete is the largest amount of artificial building materials in the world today. According to incomplete statistics, the construction waste produced in china each year can reach about one hundred million tons, and it can reach hundreds of millions of tons due to the long accumulation, which has become a serious social and environmental issues.
Such conditions can cause serious problem such as environmental pollution. This research utilizes aluminum waste as sand replacement in concrete. The use of these materials not only helps in the natural resources such as sand, aggregate, cement and other building. However, it also helps in reducing the manufacturing cost of the concrete.
End of Life (EOL) concrete fines, that is often 0–4 m, is one of the massive by-products of concrete recycling. Using this fraction into new concrete is detrimental, due to its high water absorption and mixed contaminants.

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 ...
Concrete to high-quality concrete. In this project, an installation is being built in the border region to process concrete debris into the original cement, sand and gravel components (SmartCrusher technology). The hydrated cement is regenerated in a microwave oven. This way, new high quality concrete can be made from concrete rubble.
Description. Mt. Baker Mining and Metals' shaker tables are designed from an old Deister patent, using a ramp and plateau system built into the table top, featuring excellent separation between higher density material, lower density material, and waste products.
Abstract. End of Life (EOL) concrete fines, that is often 0–4 m, is one of the massive by-products of concrete recycling. Using this fraction into new concrete is detrimental, due to its high water absorption and mixed contaminants.

A combination of heat and air classification, resulted in a proper separation of finer fraction (0 - 0.250 mm), from coarser fractions. Heating of the materials was followed by ball milling to enhance the liberation of the cementitious fraction. Experiments were carried out at different heating temperatures and milling durations.
