| Abstract: | Tests are carried out to set forth the superficial phenomena and characteristics of specimens compressed or splitted at the level of properties of material.The deterioration and mechanism of the strength of concrete cooled by air or water after sub-high temperature are analyzed.It can be used as a fundamental basis of further researches on the durability of concrete exposed to specified sub-high temperature environment. |
| |
| Keywords: | sub-high temperature environment concrete strength cooling mode |
