| Popis: | Hybrid cements represent a relatively new type of binders which combine some of the advantages of Ordinary Portland Cement (OPC), the application of mineral admixtures and alkali activation. Hybrid cements represent blends containing a low portion of OPC and a high proportion of mineral additions (such as blast furnace slag, fly ash, metakaolin ....). The paper is focused on the study of properties of mortars prepared from hybrid cements. Mortars with hybrid cements were prepared for an evaluation of the effects of the dosage and the composition of alkali activator, the dosage of OPC and the ratio between ground granulated blast furnace slag and fly ash. The results make it possible to optimize the composition of hybrid alkali activated concretes. |
