Tonne cement clinker

Sep 03, 2019 Each 1% drop in clinker factor can reduce emitted CO 2 by 8-9 kg/cement tonne. However, increasing the SCM level to lower the clinker factor usually results in somewhat poorer cement performance. For example, a 1% increase in SCM can reduce 28-day mortar strength by 0.2 - 0.8MPa, depending on SCM type, cement fineness, grinding system, and clinker characteristics

    What are Cement Clinkers? (with pictures)

    Cement clinkers are key in making many types of concrete. Cement, when mixed with water, forms a very strong alkaline solution. Gloves and eye protection should be worn at all times when working with cement, and cement should be washed from the skin immediately to prevent skin injury. Once cement hardens, it can be handled without precautions

    Clinker is the main ingredient in cement, and the amount used is directly proportional to the CO 2 emissions generated in cement manufacturing, due to both the combustion of fuels and the decomposition of limestone in the clinker production process.. From 2014 to 2018, the clinker-to-cement ratio increased at an average of 1.6% per year, reaching an estimated 0.70 in 2018; this rise
