- The high change of temperatur ( more than 7000 C) during fire will give certain impact on concrete structure. Because during this condition cooling and heating process will happen alternately. And this causes fisical ang chemical change of phase in complex way. The change can influence the quality and compresive strength of High Performance Concrete. With burning method model on burner with temperatur 4000C - 12000C and with time measured as asumed the time of fire. That the porosity of High Strength Concrete can survive until high temperatur (until 800C). The porosity can change until 65% from start point ( at room temperatur). And at the temperature more than 1000C, the porosity will be decrease until more than 100%. It becouse the decomposition will be occur on high temperatur.
