This is testimony of the Lafarge's innovation drive which allows the company to add value to waste materials from the cement manufacturing process. Water plus cement plus aggregates. The material is heated to 1,500°C before being suddenly and dramatically cooled by bursts of air. Cement acts as the binder and modifies the characteristics and uses of concrete: Aggregates, another essential ingredient in concrete, retain the intrinsic properties of the rocks that they come from. They are then crushed and transported to the plant where they are stored and homogenized. During this phase, different mineral materials, called "cement additives", may be added alongside the gypsum. History : Cement, a hydraulic binder and a key ingredient in concretes and mortars, came into widespread use during the Industrial Revolution. Following the cooling stage, gypsum is added to the clinker and the mix is then finely ground to a form of grey powder called "cement" in a finishing mill, which is similar to … BULK CEMENT. In 2007, LafargeHolcim initiated a … air-entraining agents allow concretes to withstand frost and deicing products. Why find uses for waste? Manufacturing process . Glossary.

In 2050, 70% of the world population will live in cities, twice as many as there were in 1970. Finally, the cement is stored in silos before being shipped in bulk or in bags to the sites where it will be used. The cement industry is a natural producer of CO2: Ensuring a good yieldThe reliability coefficient of a kiln is calculated by comparing the number of lost time hours to the number of operating hours. Most cements are made from clinker and additives and are usually used in the form of a powder. Cement manufacturing consumes non-renewable raw materials in large quantities and emits significant levels of CO2. The performance and characteristics of a concrete can vary greatly depending on the formula, the way it is used, etc. A superplasticizer is an additive that is mixed with concrete, mortar or grout just before the concrete is used. 60% of emissions are due to the transformation of raw materials at high temperatures (the "decarbonation" of limestone). Lafarge Cement France saw its efforts pay off when the reliability coefficient of its kilns passed from 92.8% in 2002 to 96.5% in 2006. Agricultural Lime.
