2022.6.8 Over many decades, cement has been the primary component in construction projects and is considered one of the essential industries worldwide. At the same time, it overconsumes natural resources and can negatively impact the environment through a few byproducts, such as carbon dioxide (CO2) and cement kiln dust (CKD).
Read More2021.4.30 Pan et al. (2020) recently studied the emission reduction potential from producing cement mortar and concrete blocks by mixing in a high level of alkaline blending (e.g. blast furnace slag, fly ash, and mine tailings) and discovered a yearly multi-gigatonne potential of CO 2 abatement. Therefore, reducing the clinker ratio is still the key to

2023.7.24 Depending on the manufacturer’s process, the grinding is done wet, dry, or semi-dry. In vertical shaft ball mills, 65% of the particles are smaller than 45 microns, and the balls used are around 12mm in size. The rotational speed can vary between 60 – 80 RPM. A typical ball mill can generate 3500 tons of cement per hour.

2016.11.4 Driven by increasing cement consumption, the global production of cement is projected to grow to over 5 billion tonnes worldwide by 2030 [1]. This has a profound impact on the overall level of greenhouse gas emissions, as the production of each tonne of cement results in emissions of roughly 0. 9 tonnes of carbon dioxide (CO2).

2020.8.27 The process of producing cement is highly energy intensive. The process requires procuring limestone, shell, and clay. Afterwards, the raw materials are crushed and heated at a temperature in excess of 1,000 degree Celsius to produce clinker. For producing final grade of cement, clinker is mixed with gypsum and grounded to fine powder.
