Mechanical properties of high performance concrete re-tempered in different ambient temperatures

الملخص EN

This paper studying some of the Mechanical properties of High Performance Concrete re-tempered by using G51 after 90 minute waiting at 3 different ambient temperature (23, 40, 57)starting from lab temperature to high temperature during casting which may simulate summer degree in Iraq.

The comparative made with reference concrete in the same environment.

HPC produced by adding High Reactivity Metakaolin after burning.

Compressive strength, Ultrasonic Pulse Velocity, Splitting tensile and Flexural test was made for both reference and HPC mixes.
