Portland cement plaster also known as stucco is extensively used as a coating material on the exterior surface of buildings. As such, it is expected to possess satisfactory resistance to most commonly encountered deleterious environmental conditions such as wind, rain, thermal imbalance, moisture fluctuation, detrimental soil and aggressive chemical attack. This problem is compounded when instead of the conventional casting process, it is applied through the spray process. Special care must be taken to understand the material composition in-situ, rheological and mechanical behaviour, and hygro-thermal performance. It is well known that using lightweight aggregates will reduce rebound and achieve better thermal insulation. This study will examine lightweight stucco for mechanical, thermal and hygric properties. Tests that measure shrinkage in a controlled temperature-humidity chamber will evaluate strains associated with each layer in the application of stucco. At the same time, accruing benefits to its insulating ability will be examined through ASTM and ISO methods for thermal evaluation. The proposed study will thus detail improvements to the dimensional stability, rheology, thermal transport, and mechanical properties of insulating sprayed stucco.
