In high quality concrete producing processes, choosing an appropriate batching method plays an essential role. There are two common methods to be selected: volume batching and weigh batching. Generally speaking, volume batching is not a preferred way the concrete producer may choose for proportioning the raw materials including Portland cement, aggregates and some admixtures, because there is

The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km. The limestone is excavated from open cast mines after drilling and blasting and loaded onto dumpers which transport the materials and unload into hoppers

A process for manufactures cellular concrete aggregates of at least 2 mm. 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.

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.

As concrete production keeps on increasing worldwide, so does the use and consumption of abiotic resources, such as aggregates. To corroborate this statement, the worldwide aggregates demand will raise from 45.9 to 66.3 Gt in a time span of 10 years (e.g., 2012–22) ( Freedonia, 2012 ).

The manufacture of concrete is fairly simple. First, the cement (usually Portland cement) is prepared. Next, the other ingredients—aggregates (such as sand or gravel), admixtures (chemical additives), any necessary fibers, and water—are mixed together with the cement to form concrete. The concrete is then shipped to the work site and placed
