A combination of heat and air classification, resulted in a proper separation of finer fraction (0 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.
Oct 01, 2015· A new technology of concrete recycling called C2CA (Concrete to Cement and Aggregate) aims at a costeffective system approach for recycling highvolume EOL concrete streams into primegrade aggregates and cement (see Fig. 1) . Download : .
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.
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 recycling plant from Is concrete recycling necessary? Concrete recycling systems process the residual concrete so that all the constituents can be reused, and the environment therefore incurs no additional burden at all. The screw system This is an extremely compact unit that can be supplied in either stationary or mobile form.

Concrete to highquality 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.
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.
Abstract. End of Life (EOL) concrete fines, that is often 0–4 m, is one of the massive byproducts of concrete recycling. Using this fraction into new concrete is detrimental, due to its high water absorption and mixed contaminants.
Existing construction waste recycling technologies and standards have long been applied in construction and demolition waste recycling. However, they have been essentially focused on the production and use of coarse recycled aggregates. This paper presents a technology that permits the production of high quality recycled sand.
With its innovative, highperformance and costefficient products and technologies for cold milling, soil stabilization, hot and cold recycling, concrete paving and surface mining, WIRTGEN leads the world market in road construction and repair, as well as in mining natural rock and pay minerals.
