Abstract Foamed concrete is a lightweight building material, but its high water absorption is one of its main disadvantages. The objective of this study was to fabricate, characterize and evaluate a GO/silane superhydrophobic coatings on foamed concrete surface. The results showed that the water contact angle of the foamed concrete was 165.5° and water can roll off from the surface easily. Superhydrophobic modification improves waterproof properties of the foamed concrete obviously, the water sorptivity was reduced about 97.2%. SEM results showed that the superhydrophobic surface was mainly due to the rough structure brought by GO and the low surface energy brought by silane.

GO/硅烷涂层在泡沫混凝土表面制备超疏水性

摘要 泡沫混凝土是一种轻质建筑材料,但吸水率高是其主要缺点之一。本研究的目的是在泡沫混凝土表面制造、表征和评估 GO/硅烷超疏水涂层。结果表明,泡沫混凝土的水接触角为165.5°,水很容易从表面滚落。超疏水改性显着提高了泡沫混凝土的防水性能,吸水率降低了97.2%左右。SEM结果表明超疏水表面主要是由于GO带来的粗糙结构和硅烷带来的低表面能。
