Self-levelling flooring compounds are complex products that are optimised mainly in order to obtain a good flow, a smooth and wear resistant surface, a controlled open time followed by a rapid setting and hardening and low shrinkage. In this article a standard mix design is presented that is similar to a commercial mix design, but not optimised to the flow. With this mix design it is possible to study hydration rate and properties of the hardened product. The mix design was used to study the influence on moisture properties and strength of three polymers and one thickener. The mechanical properties were clearly influenced both by the additives and the air entrainment caused by the additives, while the drying behaviour was only influenced to a minor extent.
