带纤维水泥面板陶粒泡沫混凝土复合砌块力学性能试验研究

Experimental study on mechanical properties of ceramsite foam concrete composite block with fiber cement panel

陶粒泡沫混凝土复合砌块的界面粘结能力主要受面板含水率以及面板表面状态的影响。通过开展陶粒泡沫混凝土复合砌块基本力学性能试验,测定不同条件下的试件的界面粘结强度和抗压强度,分析了面板含水率以及界面处理方式对试件粘结强度和抗压强度的影响。试验结果表明:随着面板含水率的升高,复合砌块的界面粘结强度呈现先增后减的趋势,达到最大值时的面板含水率为10%。粗糙面处理的粘结强度高于光滑面处理,且28天龄期时,因本身材料强度的差异,使用500型陶粒的试件粘结强度明显更高。拉毛处理后的面板表现出更强的界面粘结能力,同时,采用500型陶粒的试件抗压强度显著高于300型陶粒的试件,拉毛处理亦能提升试件的抗压强度。

The interfacial bonding capability of ceramic particle foam concrete composite blocks is primarily influenced by the panel moisture content and the surface condition of the panel.By conducting basic mechanical performance experiments on ceramic particle foam concrete composite blocks,the interfacial bonding strength and compressive strength of specimens under different conditions were measured.The analysis considered the effects of different Interface processing methods and moisture content on their interface bond strength and compressive strength.The experimental results indicate that,as the moisture content of the panel continuous raises,the specimen interface bonding strength shows a trend of first increasing and then decreasing,reaching its maximum when the panel moisture content is 10%.The bonding strength of specimens with rough surface treatment is higher than that of smooth surface treatment.Additionally,at the 28-day age,due to differences in material strength,specimens using 500-type particles exhibit significantly higher bonding strength.Panels treated with brushing show stronger interfacial bonding capability.Moreover,specimens using 500-type particles demonstrate significantly higher compressive strength than those using 300-type particles,and brushing treatment also enhances the compressive strength of the specimens.
