Basic Chemistry 3: Atomic weights (also known as relative atomic masses) In the old days, atomic weights were based on hydrogen with an atomic weight of 1. This meant that calcium, with an atomic weight of 40, is 40 times as massive for the same number of atoms as hydrogen. In other words, if you have 1 gram of hydrogen and 40 grams of calcium ...

Analysing raw mix control. The monitoring and control of the chemical composition of the raw meal is a key function at a cement plant, not only in terms of delivering a high-quality end product, but also for avoiding the negative impacts on a range of other production costs. The latest-generation analyser-based raw mix control provides …

Cement production is currently the largest single industrial emitter of CO 2, accounting for ∼8% (2.8 Gtons/y) of global CO 2 emissions. Deep decarbonization of cement manufacturing will require remediation of both the CO 2 emissions due to the decomposition of CaCO 3 to CaO and that due to combustion of fossil fuels (primarily …
