ABSTRACT:

Concrete is construction materials which was often used for the structure, because having ability arrest, detaom easy and big burden made in so many form at room temperature, effect of mixing of aggregate an cement with water.
At the time of fire at building, hence behaviour of concrete will change effect of improvement of temperature. More and more high burning time depth more and more burning temperature. 1994/1995 pursuant to research of Center and Development Public Work Department, Bandung. Indicating that fire mean time at 3,01 hours.
Research about influence of this temperature is specified at 5000 C and 10000 C. Both temperature treated with combution condition and soaked in water as fire extinguishing simulation. Hence at combution 5000 C when released at temperature 2000 C without soaked to happened degradation strength 43,63 % to unburned concrete. Is which burned by temperature 5000 C soake by water, strength of going down equal to 37,77 % to unburner concrete. At combution 10000 C unsoaked by water degradation pf strength equal to 87,78 %, is at 10000 C in condition 5000 C soaked by water with room temperature, concrete erupt and micro structure revalled.

Keywords : Concrete, high temperature, strength of concrete.
