    Abstract

    The level damage building effect of fire can be determined by some factors those are reached temperature and time duration of happened. Temperature effect of fire will have an effect to physical of concrete. Research to normally quality concrete fc’= 30 Mpa with different wc ratio that is 0,5 :0,55 :0,6 intended to obtain compressive strength, porosity, permeability and unit weight of concrete with fire time duration during 67, 421, 707, 360 minutes to reach temperature 400, 600, 800, 1000 oC. Results of experimental indicated that at temperature 400C until 1000C compressive strength decrease especially to concrete with wc ratio is 0,6. From regression analysis compressive strength which remain at temperature 1000 oC for wc ratio 0,5 :0,55 :0,6 respectively is 17 %, 8 %, 5 %. On research of the porosity and permeability increasing its happened, especially to concrete with wc ratio is 0,6. At high temperature unit weight of concrete will be decrease , where the pattern of reduction is similar for all wc ratio.
