HYBRID ALKALI-ACTIVATED PORTLAND CEMENTS
Original language description
The most promising way to improve the sustainability of cement is to produce blended Portland cements with supplementary cementitious materials. Blast furnace slag (BFS) is one of significant pozzolan sources used worldwide in blended cements which contributes to lowering the environmental impact of cement industry. On the other hand, the replacement of Portland clinker is connected with undesirable effects such as the reduction of early strength development. In order to overcome this disadvantage, the study deals with the development of hybrid cements in which the utilization of solid waste alkaline activator quickly awakens the pozzolanic properties of BFS. New types of blended alkali activated cements were designed to meet the European standard EN 197-1 and classified to the Blastfurnace CEM III cements in accordance with the mechanical, physical and chemical requirements. The alkali activation caused an increase of early compressive strength in comparison with reference cement and at the same time the initial setting time was delayed which is also interesting from the point of view of concrete production. Moreover, this non-traditional hybrid alkali-activated Blastfurnace cement provides considerable ecological and economical potential.
