· 1. Cement. Cement is the main binder material used to bind other building concrete materials together. It is used for making mortar and concrete during the construction process. 2. Coarse Aggregate. Coarse Aggregate forms the major body of concrete.The aggregates contribute to the overall strength of the concrete by increasing density.
· Cement evaluation logs and other cased-hole logs can indicate the strength of the set cement and whether it "s bonded to the cas.ng (far right). The out- come of a cementing job, however, depends ultimately on choosing the appropriate cement and additives to cope with particu lar well conditions. . Portland cement was developed by Joseph Aspdin
When Portland cement is mixed with the eco-friendly cementitious material to some extent, the green concrete is formed. The commonly used partial substitute for Portland cement is sand, glass aggregate, fly ash, etc. And when this substitute is added to the Portland cement, this mixture is considered as the green concrete.
· The production of cement, the main component in concrete, is responsible for around 7% of global carbon emissions. Key factors for the future of the cement industry include: optimizing quality cement production, trying to reduce the energy required per ton of cement produced, and using alternative raw materials in the concrete mix.
