Nano-structured alkaline aluminosilicate binder by carbonate mineral addition
Popis výsledku v původním jazyce
The influence of CaCO3 on nano-structured, flowability and plastic strength of alkali activated alumonosilicate binders based on metakaolin for the range of oxide ratios in a structural formula of the Na2O∙Al2O3∙(2.5-4.5)SiO2∙(12-17)H2O + (5-15%)CaCO3 system was studied. The results of the study showed that the ratios of SiO2/Al2O3 – 3.8, H2O/Al2O3 – 13.75, and content of CaCO3 of 5% by mass were the most optimal ones from the point of view of meeting requirements for these binders to be used as base in protective coatings. The results of the study showed that process flowability of the binder with optimal ratios of oxides and 5 % by mass of additive 2 hours after preparation was by 5.4% lower, being by 5 times lower than that of the binder without the additive (CaCO3). The binder containing 5% CaCO3 by mass during 2 hours after preparation exhibited the same plastic strength (37 Pa), whereas this value of the binder without CaCO3 has increased, in average by 5.5 times, affecting negatively shelf life of this binder to be used as base in protective coatings. A conclusion was made that the addition of CaCO3 intensified the nano-structured formation processes in the direction of formation of Na-Ca zeolite-like phases; shortening time required the cement stone to gain water resistance in normal conditions.
