22. Carbonization and crushability of structured sand-sodium-silicate mixtures: (Contens №5 2020); ... Methodology. Determination of ultimate compressive strength and crushability resistance was carried out on samples with dimensions of Æ50 ´ 50 mm. The samples were prepared from mixtures of quartz sand and 5 % by weight of binder material (sand-sodium-silicate mixture, phenol-formaldehyde resin), as well as quartz sand cladding with sand-sodium-silicate mixture. Sand-sodium-silicate mixture carbonization kinetics was studied in a layer of hollow glass balls, previously clad with liquid sodium sand-sodium-silicate mixture. Excerpt and determination of ball mass as per duration of their staying in the air were carried out in a climatic chamber. Ball surface appearance was recorded by microscopic photographing with an up to 25 times magnification. Influence of materials-modifiers on dehydrated sodium silicate solute carbonization was investigated by visual assessment of cladding layer surface of glass balls. For this matter, glass balls of Æ10 mm were cladded with pure or modified sodium silicate solute followed by air drying for 6 hours. Cladding layer surface quality was evaluated after 48 hours of exposure in the climate chamber at 24–28 °C with 60–85 % relative humidity. ...; Created on 30 October 2020
