Abstract
Portland cement production consumes
significant energy, a large share of which is attributed to clinker grinding.
This research investigates the influence of Power Plant Waste Gypsum (PPWG) on
clinker grindability and final cement properties. PPWG is evaluated as a
partial replacement for natural gypsum in cement, aiming to reduce
environmental impact, lower production costs, and improve energy efficiency.
Grindability was assessed using the Bond Work Index, Blaine fineness, and
particle size distribution. Mechanical performance of the resulting cements was
tested through compressive strength, setting time, and hydration behavior.
Results indicate that PPWG can be successfully integrated up to certain limits
without detrimental effects on grindability or concrete performance, while
offering sustainable management of industrial gypsum waste.
