Item Artificial Tobermoryte as Raw Material for Low Temperature Burning(Видавництво Львівської політехніки, 2013) Borovets, Zenon; Pona, Myron; Kobryn, OlesiaAbstract – The possibility and condition of wollastonite synthesis by two-stage technology which foresees the receive of intermediate phase in a form of calcium hydrosilicate (tobermorite 11,3 Ǻ) on the stage of hydrothermal treatment with its further burning to β-СаО∙SіO2 were investigated. The influence of forms of SiO2 and consistency of raw material mixture on the output of synthetic wollastonite was studied. The mineralising effect of boron oxide on the formation of wollastonite was established.Item Investigation of the process of vibro-impact interaction of vibration activator blades with two-phase environment “Hydrate lime – water”(Видавництво Львівської політехніки, 2022-02-22) Novitskyi, Yaroslav; Lutsuk, Iryna; Zagraj, Andrij; Borovets, Zenon; Lviv Polytechnic National UniversityThe process of mechanical activation of hydrated lime in the vibratory activator of the bunker type is investigated in the work. Economic and environmental effect in the production of reinforced concrete structures is achieved through the use of highly active hydrated lime as a modifying reinforcing additive to concrete based on Portland cement. Theoretical and experimental studies of the influence of vibration displacement parameters of the mixture on the rate and degree of dispersion of hydrated lime and the efficiency of vibroactivation are determined.
