摘要
本文对C30和C50两种强度等级的48块混凝土试件在20℃～600℃范围内经高温作用后,进行了强度试验,包括抗拉强度和抗压强度,总结出高温作用后混凝土强度变化规律并对其原因进行了分析.
This paper proceeded the strength experiment to 48 specimens of two kinds of strength concretes (C30 and C50) which have been performed under different temperatures, including compressive strength and tensile strength. With the increasing of temperature, the variation of microstructure of concrets was summarized, and its reason was analyzed.
