Environmental impact of concrete
Carbon dioxide emissions and climate change. The cement industry is one of the two largest producers of carbon dioxide (CO 2), creating up to 8% of worldwide manmade emissions of this gas, of which 50% is from the chemical process and 40% from burning fuel. The CO 2 produced for the manufacture of structural concrete (using ~14% cement) is estimated at 410 kg/m 3 (~180 kg/tonne density of 2 ...

Cement Production: How Cement Is Manufactured | CEMEX UK
View the interactive animation of the cement production process to learn how cement is made by CEMEX. 1. Mining the raw material. Limestone and clay are blasted from rock quarries by boring the rock and setting off explosives with a negligible impact of the environment, due to the modern technology employed. 2. Transporting the raw material.
Cement Hydration
Cement Hydration. Cement hydration involves a collection of coupled chemical processes, each of which occurs at a rate that is determined both by the nature of the process and by the state of the system at that instant. From: Cement and Concrete Research, 2011. Download as PDF.

How Concrete is Made
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 rocklike mass known as concrete.

Cement manufacturing
Summary of production process. Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of ...
