Abstract
Wynalazek dotyczy tworzywa geopolimerowego na bazie glinokrzemianów zawartych w tufie wulkanicznym. Tworzywo to zawiera tuf wulkaniczny, rozdrobniony do wielkości ziaren 10 - 800 µm i kalcynowany przez 2-4 godz. w temperaturze 700-850°C, który przynajmniej zawiera SiO2 w postaci glinokrzemianów potasowych K(Al2Si3O8) w ilości 30 do 70% masowych, K2O w ilości 5 do 20% masowych i Al2O3 w ilości 5 do 30% masowych w przeliczeniu na masę tufu, przy stosunku molowym SiO2 : Al2O3 wynoszącym 5 do 6,1. Jako alkaliczne aktywatory glinokrzemianów tworzywo zawiera sodowe i/lub potasowe szło wodne w roztworze wodnym wodorotlenku sodu i/lub potasu. Stosunek molowy składników kompozycji tworzywa jest taki, że Na2O/SiO2<0,15, Na2O/Al2O3<1,0, H2O/Na2O>10, K2O/SiO2<0,20; K2O/Al2O3<1,5; H2O/K2O>5. Ujawniono również sposób wytwarzania tworzywa geopolimerowego na bazie glinokrzemianów zawartych w tufie wulkanicznym, alkalicznych aktywatorów i wody, który polega na tym, że materiał stanowiący źródło glinokrzemianów miesza się z wodnym roztworem wodorotlenku metalu alkalicznego i szkła wodnego.The invention relates to a geopolymer material based on aluminosilicates contained in volcanic tuff. This material contains volcanic tuff, ground to grain size 10 - 800 µm and calcined for 2-4 hours. at a temperature of 700-850 ° C, which at least contains SiO2 in the form of potassium aluminosilicates K (Al2Si3O8) in an amount of 30 to 70% by mass, K2O in an amount of 5 to 20% by mass and Al2O3 in an amount of 5 to 30% by mass calculated on the mass of tuff , with a SiO2: Al2O3 molar ratio of 5 to 6.1. As alkaline activators of aluminosilicates, the material contains sodium and / or potassium water in an aqueous solution of sodium and / or potassium hydroxide. The molar ratio of the components of the plastic composition is such that Na2O / SiO2 <0.15, Na2O / Al2O3 <1.0, H2O / Na2O> 10, K2O / SiO2 <0.20; K2O / Al2O3 <1.5; H 2 O / K 2 O> 5. Also disclosed is a method for producing geopolymer material based on aluminosilicates contained in volcanic tuff, alkaline activators and water, which consists in the material being the source of aluminosilicates being mixed with an aqueous solution of alkali metal hydroxide and water glass.
