HCSA高性能混凝土膨胀剂制备的补偿收缩混凝土具有膨胀能大、补偿收缩效果好和对湿养护依赖性低等优点。德晟祥广场地下工程采用补偿收缩混凝土混凝土结构自防水技术,取消柔性卷材外防水,使用GB23439的Ⅱ型产品HCSA膨胀剂。通过严抓膨胀剂质量,以限制膨胀率、强度和施工性能为核心优化配合比,严控施工环节,在保证工程质量前提下,缩短工期、节约工程造价。
HCSA high-performance concrete expansive compensator shrinkage-compensated concrete has the advantages of large expansion energy, good compensation and shrinkage effect and low dependence on wet curing. De Sheng Cheung Square underground project uses compensation shrinkage concrete structure self-waterproofing technology, the elimination of flexible membrane waterproofing, the use of GB23439 HCSA type II expansion agent. By strictly controlling the quality of expansive agent, optimizing the compounding ratio with the limit of expansion rate, strength and construction performance as the core, strictly controlling the construction links, shortening the construction period and saving the project cost under the premise of ensuring the project quality.
