Effect of admixtures on the fresh and hardened properties of modern rendering systems
Artikel i vetenskaplig tidskrift, 2006

In this paper, the first part of a doctoral project studying the chemistry and mechanism of modern rendering systems is presented. This study is focused on polymer modified renders, a type of material that possesses several superior properties to conventional renders, such as better crack resistance, adhesion to substrate and flexural strength. This improves both the workability and the durability of the material. The main part of the project consists of experimental studies focused on the interaction between composition, hardening process, microstructure and transport properties. These studies concentrate on a small but most relevant selection of rendering systems with different binders and admixtures. Different studies such as vapour transport, capillary water absorption and the drying process give good prerequisite durability of rendering systems. The results of the project will give a better understanding of rendering systems formulated and their constitutive components.
