摘　　要：显微岩相学方法是分析混凝土火灾损伤程度的有效手段之一,但是不适当的样品制备过程可能导致错误判断。在总结常用的显微分析样品制备过程中可能出现问题的基础上,根据火灾损伤混凝土在样品制备过程中较易受损的特点,提出了建议的样品制备方法。Micro-petrographic method is one of the effective techniques for evaluating fire damage on concrete,however, improper sample preparation may lead the method to be misused.It shows that the usual sample preparation procedures have a good chance of causing misuse in petrographic examinations, since the fire damage on concrete is liable to disturbance during sample preparing procedures.A specimen preparation procedure is proposed for the petrographic examination of fire damage.
