膨胀混凝土系列具有抗裂、防渗、抗冻、耐蚀等非常优越的性能,可广泛用于屋面、地下、水工、海工等要求抗裂、防渗、自防水的结构工,采用这项技术可降低工程造价、大大短施工限,特别是能达到永久性防水抗渗的,无需经常进行修补,这是一般沥青等柔性防水材料不能作到的。因此从长期效果来看,其经济社会效益更为显著。为了推广膨胀混凝土系列的科研成果,开 The series of expanded concrete has excellent performances such as crack resistance, seepage resistance, frost resistance, corrosion resistance, etc., and can be widely used in structural workers such as roofing, underground, hydraulic, offshore, which require crack resistance, seepage resistance, and self-water resistance. This technology can reduce the project cost, greatly shorten the construction limit, in particular, can achieve permanent waterproof impermeability, without frequent repairs, which is generally flexible waterproof material such as asphalt can not be done. Therefore, from the long-term effect, its economic and social benefits are more significant. In order to promote the scientific achievements of the expanded concrete series,
