This study investigates the effects of various components on the performance of aerogel-phosphogypsum (APG) thermal insulation mortar. This study investigates the effects of various components on the performance of aerogel-phosphogypsum (APG) thermal insulation mortar, with a special focus on optimizing the composition to enhance mechanical properties. The parametric range explored included phosphogypsum content from 10 to 30 wt%, hollow glass microspheres (HGS) from 5 to 15 wt%, and aerogel slurry from 40 to 80 wt%. Our findings reveal that the optimal composition, which provided the best balance between thermal insulation and mechanical strength, consisted of 20 wt% phosphogypsum, 10 wt% HGS, and 60 wt% aerogel slurry. Notably, the introduction of 0.14 % hydroxypropyl methylcellulose (HPMC) and 1.89 % re-dispersible polymer powder (RPP) significantly enhanced the compressive strength of the mortars. Specifically, compressive strength increased from an initial 0.05 MPa–0.27 MPa post-enhancement with HPMC and RPP. This research provides a detailed understanding of how individual components influence the formulation of APG and offers insights for optimizing the overall performance of aerogel-phosphogypsum composites, contributing to advancements in sustainable building materials.

高性能气凝胶磷石膏保温砂浆的创新开发：成分优化和机械性能增强


本研究调查了各种成分对气凝胶磷石膏 （APG） 保温砂浆性能的影响。本研究调查了各种成分对气凝胶磷石膏 （APG） 保温砂浆性能的影响，特别关注优化成分以提高机械性能。探索的参数范围包括磷石膏含量为 10 至 30 wt%，空心玻璃微球 （HGS） 为 5 至 15 wt%，气凝胶浆料为 40 至 80 wt%。我们的研究结果表明，在隔热和机械强度之间提供最佳平衡的最佳成分由 20 wt% 的磷石膏、10 wt% 的 HGS 和 60 wt% 的气凝胶浆料组成。值得注意的是，0.14 % 羟丙基甲基纤维素 （HPMC） 和 1.89 % 再分散聚合物粉末 （RPP） 的引入显著提高了砂浆的抗压强度。具体来说，HPMC 和 RPP 增强后抗压强度从最初的 0.05 MPa–0.27 MPa 增加。这项研究详细介绍了单个成分如何影响 APG 的配方，并为优化气凝胶-磷石膏复合材料的整体性能提供了见解，从而为可持续建筑材料的进步做出了贡献。
