复合发泡钢筋混凝土楼板设计及承载能力试验研究

Design and Experiment Study on Bearing Capacity of Light Weight Aerated Concrete Combined Slabs

加气混凝土质量轻,普通水泥砂浆抗压性能好,通过对复合发泡钢筋混凝土楼板试验加载以及理论验证,对测得的复合发泡钢筋混凝土楼板承载力和跨中挠度等试验结果与数据进行分析,结果表明这种形式楼板在结合两种材料特点的同时,拥有一定的强度和安全储备,并且弥补了现浇钢筋混凝土楼板和预应力多孔板保温性能差等缺点。如果理论成熟后将该形式楼板实际应用,复合发泡钢筋混凝土楼板由于具有自重轻、保温性能好、强度可靠和综合造价低等显著优点,将会有长远的经济效益。

Combining the characteristics of both light weight aerated concrete and ordinary cement mortar which has high compression strength, light weight aerated concrete combined slabs were designed. Through the slab-loading test and the theoretical analysis of displacement and bearing capacity which were obtained from the experiment, it was found that the slab has adequate strength and it brings the advantages of the aerated concrete and mortar together, meanwhile, shortcomings of concrete slab and the prestressed...
