摘要

水泥工业面临着缺乏替代熟料的补充胶凝材料的挑战。这主要适用于由于冶金工业的变化而最常用作水泥主要成分的粒状高炉炉渣，以及由于世界上放弃化石燃料而产生的硅质粉煤灰。普通水泥的一种潜在的新主要成分可能是煅烧泥灰岩，每个波特兰熟料生产商都可以大量获得这种泥灰岩。本文对波兰奥波莱附近的Folwark矿床的煅烧泥灰岩进行了研究。试验结果表明，煅烧后的灰泥具有火山灰-水力特性，可以代替水泥中的粒状高炉矿渣和硅灰。在900℃下煅烧Folwark灰岩获得了最佳的火山灰水力性能

Calcined marl as a potential main component of cement

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