Calcined marl as a potential main component of cement

The cement industry is facing the challenge of a lack supplementary cementitious materials substituting clinker. This applies primarily to granulated blast furnace slag, most commonly used as main component cements, due changes in metallurgical industry, and siliceous fly ash abandonment fossil fuels world. A potential new common cements may be calcined marls, which are available large quantities for every producer Portland In this article, research was carried out on marls from Folwark deposit, near Opole, Poland. conducted experiments showed that after calcination show pozzolanic-hydraulic properties can replace both slag silica composition cement. best obtained by at 900°C
