Abstract |
This study evaluated spalling and internal temperature distribution after elevated temperatures test for high strength concrete ( fck = 60 MPa) column member with various polypropylene fiber volume fractions. The ISO-834 time-temperature curve was used for measurement of fire resistance properties. As the result of test, average internal temperature results indicated to low temperature in increased polypropylene fiber volume fraction. But, the highest internal temperature results show that does not difference in proportion of polypropylene fiber volume fractions.
