Utilization of lignosulfonate plasticizer in alkali-activated materials
 Zetocha, Martin ; Hrubý, Petr (oponent) ; Kalina, Lukáš (vedoucí práce)
This bachelor thesis deals with the use of lignosulfonate-based plasticizers in alkali-activated materials. The effect on the paste mixture of activated blast furnace slag using sodium hydroxide, water glass with different modulus and sodium carbonate was monitored. The effect of a mixed lignosulfonate-based plasticizer into different mixtures, on workability, mechanical properties and rheology of the mixture was monitored. Activators in the mixtures were found to be an important factor. The mixture which showed the best reaction with lignosulfonate was using NaOH as activator. In attempts to understand the rheological properties of the studied mixtures, a zeta potential was observed as a key factor in the behaviour of these mixtures. It manifested interesting trends. The zeta potential values gave us a closer look at the surface charge of the blast furnace slag particles. This has been shown to be a key factor in assessing the effectiveness of the plasticizer. These findings will be taken into account and further discussed in this work.
