Abstract
The properties of alkaline activated brick dust mixed with different amounts of water glass with a silicate modulus (M) of 1.0 were studied in connection with the temperature of curing. The influence of the amount of alkaline solution and the temperature of curing on the microstructure and mechanical properties of hardened materials was studied. The flexural and compressive strengths of the hardened products, as well as their microstructure, were determined. Part of the samples was stored under laboratory conditions (20 °C) for 7 and 28 days, other set of samples was stored at 60 °C for 7 and 28 days. One set of samples was treated for 7 days at 60 °C and 21 days at 20 °C. The microstructure of the hardened products was studied by means of porosimetry and scanning electron microscopy.
Vlastnosti alkalicky aktivovaného cihelného prachu smíchaného s různým množstvím vodního skla se silikátovým modulem 1,0. Byl studován vliv množství alkalického roztoku a teploty ošetření na mikrostrukturu a mechanické vlastnosti připravených materiálů. Byly stanoveny pevnosti v tahu za ohybu a tlaku. Výsledky se lišily podle různého typu ošetření vzorků. Rovněž byla studována mikrostruktura ztvrdlých produktů.
