| Abstract | Nowadays, the energy efficiency and moderation of indoor environment of buildings became important topic in the field of building physics. Moisture occurrence in building construction poses a significant task for building designers and material engineers. Among other factors, a high level of relative humidity has negative effect on the work efficiency and health of building inhabitants. The presented paper is aimed on the analysis of chosen superabsorbent polymers (SAPs) and its influence on properties of newly developed interior plasters. The identification of optimal ratio between superabsorbent polymers and plaster mixture from the point of view of the workability of fresh mixtures is done. Also, the effect of water/dry mixture ratio is studied according to enhanced absorption capability of SAPs. Specific attention is paid to hygric properties, the determination of apparent moisture diffusivity, water vapor resistance factor and estimation of sorption isotherms. Obtained results directly point to significant effect of SAP admixture on material properties of developed plasters. Namely, addition of up to 3 wt.% of SAPs shifts the water absorption coefficient almost ten-times, while the total open porosity is increased only about 20%. Such materials can be applied for the damped areas or places where increased water transport parameters play an important role for the efficient moisture removal. |
