摘要

处理后的石膏废物的一种利用方法是在石膏混合物中生产石膏块。石膏砌块可用于标准的室内和室外应用,由石膏、水、PP微纤维制成,并用泡沫减轻,泡沫是由泡沫添加剂和水产生的。最重要的是,泡沫的数量显著影响所得材料的体积密度,而体积密度对机械和热性能有重大影响。PP微纤维的使用对泡沫结构的整体稳定性有积极的影响,这导致抗压强度的增加,同时保持良好的保温性能。

Dependence of mechanical and thermal properties on the composition of lightweight gypsum composites
One of the ways to use the treated gypsum waste is in gypsum mixtures for the production of gypsum blocks. Gypsum blocks can be used in standard interior as well as exterior applications and are made of gypsum, water, PP microfibres and are lightened with foam, which is created from a foaming additive and water. Above all, the amount of foam significantly influences the bulk density of the resulting material, and the bulk density then has a major influence on the mechanical and thermal properties. The use of PP microfibres had a positive effect on the overall stability of the foamed structure, which resulted in an increase in compressive strength while maintaining good thermal insulation properties.
