1. 毕业设计(论文)主要内容:

装配式建筑具有质量稳定、生产效率高以及环境污染小等优势,因此其推广利用不断深化。蒸压养护可以有效提高水泥混凝土的早期强度,从而加快模具周转率,提高混凝土生产效率。但是,蒸压养护引起的热损伤对水泥混凝土的耐久性存在负面影响。硫铝酸盐水泥具有快凝早强的性能特点,一方面,硫铝酸盐水泥水化放热集中;另一方面,其主要水化产物钙钒石可以作为晶种诱导水化,也可以促进晶体骨架的形成。因此,常温养护条件下,硫铝酸盐水泥-硅酸盐水泥复合体系有望实现早强。设计(论文)主要内容:1. 文献调研,了解国内外相关研究概况和发展趋势,了解选题与社会、健康、安全、成本以及环境等因素的关系;2. 研究硫铝酸盐水泥掺量(0-15%)对硅酸盐水泥力学性能、体积稳定性以及渗透性的影响规律;3. 研究水灰比(0.3,0.4,0.5)对硫铝酸盐水泥-硅酸盐水泥复合体系早强性能的影响;4. 开展微观试验,系统分析硫铝酸盐水泥-硅酸盐水泥复合体系的早强机理;5. 分析总结试验数据,撰写毕业论文。
