Concrete rehydration after heating to temperatures of up to 1200 C
Original language description
The presented research involves the study of the possible regeneration of cement binder in concrete subjected to high temperatures. An ongoing experimental program is simulating the heating of a concrete structure by a fire during which the temperature in the structure gradually increases. The experimental program is designed to analyze concrete behavior after heating to 200 - 1200 C and is investigate investigating the consecutive reactions of phases (which originate after heating) with water. The laboratory specimens (40x40x160 mm) are manufactured from fine-grained concrete with a water to cement ratio of w/c = 0.45. After heating and cooling, the specimens are placed under the following conditions for a time period of 2 months: (i) laboratory conditions (t = 22 C, R.H. = 55 %), (ii) water (t = 22 C) and (iii) laboratory conditions (t = 22 C, R.H. = 55 %) with periodical immersion of the specimens in water. To investigate the mechanism of concrete regeneration mercury intrusion poro
