Abstract


The development of the crystalline microstructure of a hydrating self-leveling compound (SLC) was analyzed using a two-dimensional XRD (GADDS). The application of non-destructive micro-diffraction with the GADDS, combined with a custom-made sample holder, made it possible to carry out position-sensitive in-situ measurements of a Calcium-Aluminate-Cement-(CAC)- dominated SLC. Different substrates were used in the measurement procedures so as to acquire data regarding the influence of the properties of the ground surface on the process of hydration. The results show that the crystalline microstructure is strongly affected by the availability of free water. The strongly vertically-fluctuating water-content of the hydrating mortar, which is mainly influenced by outside conditions, has a very significant effect upon the resulting ettringite content. This fact is also reflected in the resulting microstructure of the cured SLC. © 2012 Elsevier Ltd. All rights reserved.
