Dust emission from crushing of hard rock aggregates ...

01/03/2019  Five quarries processed granitic rock material and one limestone, and rock material was the most determining factor of dust emission besides the number of crushing units in the crushing circuit. In quarries applying secondary crushing, Quarry 3 processing limestone dust emission was approximately 50% lower compared to other quarries processing granitic rock material. This result is

Environmental impact of concrete - Wikipedia

One reason why the carbon emissions are so high is because cement has to be heated to very high temperatures in order for clinker to form. A major culprit of this is alite (Ca 3 SiO 5), a mineral in concrete that cures within hours of pouring and is therefore responsible for much of its initial strength.
