Aggregate impact value is a measure of toughness or resistance to suddenly applied loads. The impact loss of aggregates used in the concrete wearing course should be less than 30%. The impact value of the unprocessed aggregates was found as 32.12%, while it was 18.22% for aggregates.
Numerical optimization based on the RSM model identified optimal grinding parameters: a ball-to-material ratio of 1.40, a milling time of 0.843 hours, and a milling speed of 300 rpm. These parameters are recommended to achieve the target compressive strengths of 25 MPa at 20% CGP substitution and 10 MPa at 50% CGP substitution.
Cement industries generate massive amounts of greenhouse gas (GHG) emissions. As a fast-growing economy in Southeast Asia, Indonesia consumed more than 62 Mtons of cement in 2020.
