The invention relates to the field of building concrete materials, and provides heat-insulation and low-hygroscopicity aerated concrete for energy-saving buildings and a preparation method. Accordingto an aerated concrete block prepared by the invention, the outer surface is provided with a super-hydrophobic layer with low surface energy, so that external moisture can be prevented from invading into concrete; and the surface of the inner duct wall also has super-hydrophobicity, so that invasion and diffusion of water in concrete can be greatly reduced. Under the combined action of the super-hydrophobic outer surface and the super-hydrophobic inner pore channel wall of the concrete block, the obtained aerated concrete has low hygroscopicity, can resist moisture invasion in a high-humidityenvironment, maintains a low heat conductivity coefficient, and prevents the heat insulation effect from being greatly reduced.
本发明涉及建筑混凝土材料领域，提供了一种节能建筑用隔热保温、低吸湿性的加气混凝土及制备方法。本发明制备的加气混凝土砌块，外表面具有低表面能的超疏水层，可防止外部水分向混凝土内部入侵；内部孔道壁的表面也具有超疏水性，可大大降低水分在混凝土内部的入侵扩散。在混凝土砌块的超疏水外表面及超疏水内部孔道壁的共同作用下，所得加气混凝土具有低的吸湿性，在高湿度环境中可抵御水分入侵，保持低的导热系数，防止隔热保温效果大幅下降。
