项目摘要
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.
波特兰水泥灰泥也称为灰泥,广泛用作外表面上的涂层材料
建筑物。因此,预期其对最常见的细菌具有令人满意的抗性。
有害的环境条件,如风、雨、热不平衡、湿度波动、有害的
土壤和侵蚀性化学侵蚀。这个问题是复杂的,当代替传统的铸造
工艺,它是通过喷涂工艺应用。必须特别注意理解材料
组合物原位、流变和机械行为以及湿热性能。众所周知的是
使用轻质骨料将减少回弹并实现更好的隔热效果。本研究将
检查轻质灰泥的机械、热和湿度特性。测量收缩的测试,
受控温度-湿度室将评估与应用中的每层相关的应变,
灰泥同时,通过ASTM和ISO检查其绝缘能力的累积效益
热评价方法。因此,拟议的研究将详细说明尺寸稳定性的改进,
流变学、热传递和绝缘喷涂灰泥的机械性能。
