How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

1. Batching. It is the main thing in the Concrete Manufacturing Process. The measurement of materials like aggregates, cement, water necessary for preparing different grades of concrete is Batching. It is by two processes. One is volume and other is weight batching. The volume batching is by mixing materials with its volume.

The current study has shown that the production of recycled concrete aggregates from waste concrete, has significant environmental benefits. It is suggested that governments may consider measures such as imposing higher taxes on production of crushed natural aggregates while keeping lower taxes for recycled concrete aggregates. Such measures would lead to reduction in consumption of natural

Manufacturing process In theory, producing aggregates simply involves crushing rock. In practice, it is much more complex, as standardized sizes and homogenous aggregates must be obtained.

In the past decades, the demand for concrete production has been increasing along with the consumption of natural aggregates. The process requires large amounts of materials that significantly contribute to the global warming and environmental impacts. This study deals with the life-cycle assessment (LCA) of concrete production process

Concrete production. The ingredients used to manufacture concrete. Concrete is a building material made by mixing aggregates and sand with a binding agent (usually cement) and, if necessary, with additives. The performance and characteristics of a concrete can vary greatly depending on the formula, the way it is used, etc.

Cellular concrete aggregates sized between 2 and 25 mm and having a bulk density in the dry state of between 200 and 600 kg/m 3 enable their agglomeration by a binder for the manufacture of lightweight and insulating concrete or for the manufacture of slabs, screeds, formwork walls or prefabricated parts.

The recycled-concrete aggregate has been satisfactorily used as aggregate in granular subbases, lean-concrete subbases, soil-cement, and in new concrete as the primary source of aggregate or as a partial replacement of natural aggregate. Recycled-concrete aggregate generally has higher absorption and lower specific gravity than natural aggregate. This results from the high absorption of the

This paper concerns the use of fine recycled concrete aggregates to partially or globally replace natural fine aggregates (sand) in the production of structural concrete. To evaluate the viability of this process, an experimental campaign was implemented in order to monitor the mechanical behaviour of such concrete. The results of the following tests are reported: compressive strength, split
