Аннотация | The combination of factors was established for using high-calcium fly ash (HCFA) as a binder material of high early and long-term strength: (1) high dispersity of microspherical HCFA, 90% <10μm; (2) the positive effect of polycarboxylate superplasticizer, that allowed to use water / binder=0.25; (3) formation of finely mixed hydrate phases such as portlandite, ettringite, calcium carboaluminate hydrates and cryptocrystalline calcium hydrosilicates. X-ray powder diffraction quantitative phase analysis of initial HCFA and hydration products in high-strength specimens was performed, which contributes to understanding phase transformations of HCFA during hydration and to improving the properties of the binder. | |
