“…The higher the sulfate source surface area, the higher its solubility. Therefore, as observed by Barbosa et al [95], the increase in gypsum fineness anticipates the sulfate depletion and renewed C 3 A hydration. Thus, a higher calcium sulfate fineness tends to increase the sulfate demand of the cement.…”

“…Nustatyta, kad esant cemento dideliam C2S ar C3S kiekiui, betono mišinių ribiniai šlyties įtempiai ir plastinė klampa atitinkamai didėja ir mažėja. Dils et al (2013), Mardani-Aghabaglou et al (2017) ir Barbosa et al (2018) taip pat nustatė, kad esant cemento dideliam smulkumui, C3A ir šarmų kiekiui ir mažam sulfatų kiekiui (nuo 1 iki 3 % cemento masės), cementinių mišinių ribiniai šlyties įtempiai ir plastinė klampa padidėja -mišinių apdirbamumas pablogėja.…”

“…Moreover, the optimum sulfate content is also affected by the physics, chemical, and mineralogic properties of sulphate source. The higher the sulphate solubility, the higher the optimum sulfate content (Barbosa et al 2018).…”
