Influence of expansion admixtures on the properties of water‐glass‐based refractory pastes
Source abstract
Abstract
Abstract Water‐glass‐based pastes show good prospect for high‐temperature applications, but they are subject to substantial dry‐shrinkage. Silicon and aluminum powders were added to prevent the dry‐shrinkage. The influence of them on compressive strength, bonding strength and volume of the pastes was discussed. SEM , XRD , and TG / DSC were employed to study the influencing mechanisms. The results show that Si and Al effectively prevented the dry‐shrinkage; Al improved compressive strength and bonding strength, while Si was bad for bonding strength. When Al dosage was 6%, the pastes presented mild expansion of 1.05%, the compressive strength increased by 8.9%, and the bonding strength by 33.4%.
