Effect of an Aluminosilicate Disperse Additive on Behaviors of Autoclave Silicate Materials

In this research, a phase formation in CaO–SiO2–Al2O3–H2O binding system under hydrothermal conditions was studied. The novelty of article lies the quantitative full-profile X-ray diffraction (XRD) analysis used to determine kinetics mineral binder “lime–granite modifier (GMM)”. polymineral is described detail, as well relationships between composition newly formed phases and mixture ratios were determined. Phenomenological model “lime–GMM” proposed. results obtained allow demonstration that characterized by superposition hydration geopolymerization. properties (strength, density, water absorption, porosity) compressed autoclave-hardened materials with addition granite introduced instead part sand an aggregate have been maximum increase strength (more than 50%) observed at content 15%. This due rational neoplasms, compaction structure pressed products optimization their pore space, which confirmed data analysis, scanning electron microscopy method gas adsorption.
