With low penetration, the spalling of high strength concrete (HSC) at elevated temperatures which seriously affect the performance of reinforce concrete structure might occur.
高强混凝土的渗透性很低,高温下可能出现爆裂破坏现象,严重影响混凝土及其内部钢筋的结构使用性能。
The superposition between fracturing and explosive spalling plays a key role in the multi-layer damages of the lining concrete.
裂隙的扩展和爆裂作用的叠加是衬砌混凝土发生多层剥落的重要原因。
The conclusions are helpful for understanding the spalling of high performance concrete at elevated temperatures, and would promote further usage of high performance concrete.
为了解在高温下高性能混凝土剥落的结论是有帮助的,并会进一步促进使用高性能混凝土。
The multi-layer explosive spalling damages depend strongly on the high humidity of the lining concrete, the high temperature and.
混凝土的湿度大、火灾温度高且持续时间长是发生多层爆裂损伤的重要条件。
Therefore if concrete structures are fired at high stress level, they will be cracked after cooling down and develop spalling damage due to the LITS.
因此,由于存在LITS,如果混凝土构件在较高的应力水平下遭受火灾,火灾后混凝土构件会开裂或爆裂。
Therefore if concrete structures are fired at high stress level, they will be cracked after cooling down and develop spalling damage due to the LITS.
因此,由于存在LITS,如果混凝土构件在较高的应力水平下遭受火灾,火灾后混凝土构件会开裂或爆裂。
