Life Cycle Assessment of Concrete

This raw material, called raw meal, is fed into a rotating kiln either wet or dry. Dry material is more often used since this is more energy efficient, as a wet kiln uses twice as much energy. The temperature in the kiln is approximately 1450 °C.4 The calcination process begins when the material

Concrete Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past, lime based cement binders, such as lime putty, were often used but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete

Recent advances in the concrete industry to reduce its

Dec 01, 2020 The carbon dioxide emission from the concrete industry can be classified into two major groups which are from the raw material and concrete construction as shown in Table 2. The majority of the carbon dioxide emissions are from the mining, processing and transportation of raw materials used for making concrete.

CONCRETE MATERIALS AND TESTING

The manufacturing process known as the dry process is the most widely used at present. This consists of grinding the individual raw materials and feeding at controlled amounts into a rotary kiln and burning until they fuse into small lumps or balls called clinkers. In the wet process, a

Concrete Wikipedia

The concrete solidifies and hardens through a chemical process called hydration. The water reacts with the cement, which bonds the other components together, creating a robust, stone-like material.

Cement Manufacturing Process: How the Cement is Made?

All the cement plants set up after 1980 use the dry process for the manufacture of cement. In this process, the calcareous materials such as limestone are crushed and stored in silos or storage tanks. The argillaceous material such as clay is thoroughly mixed with water in a container known as the wash mill. This washed clay is stored in basins.
