传统的刚性屋面开裂现象引起的渗漏已称之为“通病”。无论是城市还是农村屋面的渗漏随处可见,原因是多方面的。但其主要原因是建筑物屋面长期受到雨、雪、冰、霜的侵蚀,特别是夏季酷热的阳光幅射后如突遇雷雨袭击,温差变化很大,而钢筋网片细石混凝土的热胀冷缩值为7‰,屋面防水层有时干,有时湿,在潮涨冷热干缩的反复作用下,发生裂缝出现渗漏就在所难免。为了克服混凝土抗拉强度低、抗裂性差、脆性大、易龟裂的弱点,世界各国的建材科研工作者在近几十年来进行了大量的研究工作,认为一是通过对 Leakage caused by the cracking phenomenon of traditional rigid roofs has been referred to as “common problems.” Whether it is the leakage of urban or rural roofs, there are many reasons. However, the main reason is that roofs of buildings are eroded by rain, snow, ice, and frost for a long time. In particular, after the hot sunshine in summer, such as sudden thunderstorms, the temperature difference changes greatly, and the thermal expansion of fine mesh concrete with reinforced mesh The cold shrinkage value is 7‰, and the roof waterproof layer is sometimes dry and sometimes wet. Under the repeated action of hot and cold shrinkage, leakage of cracks is inevitable. In order to overcome the weaknesses of concrete with low tensile strength, poor crack resistance, brittleness, and easy cracking, building material researchers in various countries have conducted a great deal of research in recent decades.
