Description
技术领域
本发明属于建筑工程技术领域,具体是一种秸秆混凝土装配式复合墙体施工工艺。
背景技术
基于目前我省农业废弃的大量玉米秸秆资源,利用玉米秸秆同时采用其他功能材料配制 轻骨料混凝土砌块,并复合玉米秸秆混凝土保温板墙体,把玉米秸秆混凝土复合墙体低能耗 设计和装配式施工过程有效结合。
传统的轻骨料混凝土,因轻骨料特性而极少使用玉米秸秆。即使有研究玉米秸秆作为骨 料的,也只是针对于其作为添加材料。本发明运用装配式玉米秸秆混凝土保温板与混凝土砌 块复合,把玉米秸秆混凝土复合墙体耗能设计和装配式施工过程统一考虑。本发明使建筑物 墙体达到低能耗及环保的要求,有效减少固体废弃物对环境污染,降低造价,形成秸秆混凝 土装配式墙体。本发明不仅能够有效减少固体废物对环境的污染,同时也解决了对秸秆废弃 物的处理,节约了资源,减少了资金的消耗,创造了社会和经济双重效益。
发明内容
本发明主要基于目前我省农业废弃的大量玉米秸秆资源,深化现行轻骨料混凝土的研究 成果,利用低能耗玉米秸秆混凝土复合墙体技术,将玉米秸秆混凝土的制备、墙体设计和装 配式施工过程统一。采用功能材料作为添加材料,完成其为承重材料及保温材料所需的性能 指标,项目的研究为玉米秸秆混凝土墙体大规模推广应用奠定理论基础。
