序言比较好的混凝土结构应具有良好的耐久性和抗腐蚀性。但在某些侵蚀性的环境中,混凝土基础很容易受到许多特殊形式的化学腐蚀,应考虑采取某些预防措施,以保证结构的寿命能达到设计要求。目前有大量的实践证明,凡没有采取适当安全保护措施的,包括桩在内的混凝土基础,都遭受到严重的破损。对混凝土的侵蚀,主要来自自然界和工业生产两个方面。
The preamble better concrete structure should have good durability and corrosion resistance. However, in some aggressive environments, concrete foundations are susceptible to many specific forms of chemical attack and certain precautions should be taken to ensure that the structural life of the structure meets the design requirements. At present, a great deal of practice has proved that concrete foundations, including piles, that have not taken appropriate security measures have been severely damaged. The erosion of concrete, mainly from nature and industrial production in two aspects.
