| Title of the article | Influence of calcined clays additions on the composition of reaction products and properties of compositional alkali-activated slag cements with low content of alkali reactant |
| Abstract. | Problem statement. The purpose of the study is to investigate the features of the property- and structure-formation processes of binary ground granulated blast furnace slag – calcined clays cements activated by 4M NaOH concerning percentage, amount and chemistry of reactive phase of calcined clays. Results. The main reaction products of compositional alkali-activated slag cement were C-N-(A)-S-H gel, calcite, zeolites, faujazite, analcime. Compositional alkali-activated slag cement incorporated with 28 days compressive strength up to 30 MPa is proposed as a result of performed studies. Conclusions. It is stated that thermally treated clay with a 60 % of reactive phase was found to be suitable as a supplementary precursor to granulated blast furnace slag. The significance of the results obtained for the construction industry lies in the fact that the presented results contribute to the development of theoretical basis, raw materials base and range of non-clinker low-temperature mineral binders. |
