Moisture Resistance and Durability of the Ternary Gypsum-Based Binders

Abstract:

The moisture resistance of the ternary gypsum-based materials with metakaolin was investigated. Materials with metakaolin have lower porosity and higher strength than gypsum-lime binder without metakaolin. While material without metakaolin lost compressive strength in the wet environment, the strength of the ternary binders increased. Therefore it can be concluded that the gypsum – lime mixtures with the metakaolin can be used in the environment with higher humidity, e.g. in the exterior.
