More than 300 prismoid concrete specimens with calcareous aggregate were made . three factors , temperature in fire , standing time and cooling type and cure methods after cool , were considered to simulate possible appearance in fire and after fire . many test schemes were planned for different purposes 设计制作了300余个钙质骨料混凝土棱柱体试件,为了模拟火灾时及火灾后可能出现的情况,分别考虑了不同的火灾受火温度、静置时间和冷却及冷却后的养护方式三种影响因素,根据试验目的的不同,设计了多种试验方案。
