01.11.2009This study confirmed that the compressive strength values of concretes produced by addition of these steel-making slags up to 30mass% were within the values of Grade-325 and Grade-425 steel-making slag cement. This is an attractive alternative for cement manufacturers, because calcined material is expensive, and slag substitutes are

Throughout history, cementing materials have played a vital role and were used widely in the ancient world. The Egyptians used calcined gypsum as a cement and the Greeks and Romans used lime made by heating limestone and added sand to make mortar, with coarser stones for concrete. The Romans found that a cement could be made which set under

copper slag in cement mortar. Test cubes of mortar were built according to the standard Nch 2260, Of1996 (INN, 1996a) in the form of prismatic bars having, dimensions of 40 x 40 x 160 mm (width, height and length) with mixtures of cement, water and sand. It was observed that the compressive strength of mortar using copper slag is higher than the values achieved in

About this report. The direct CO 2 intensity of cement production increased about 1.5% per year during 2015-2021. In contrast, 3% annual declines to 2030 are necessary to get on track with the Net Zero Emissions by 2050 Scenario. Sharper focus is needed in two key areas: reducing the clinker-to-cement ratio (including through greater uptake of
