Abstract :
Due lo the heat, the concrete would have cracked, spalling, and loss of strength and discoloration. Specimens in this study cuboid with a size of 15 cm x 15 cm x 15 cm and the quality of K-250 concrete with Jly ash substilution of 5%, 10% and 15%. Concrete is left at room temperature (23 °C) and heated at 300 °C heating temperature, 450 °C and 600 °C for an interval of 1, 2 and 3 hours. S ubstitution 5% Jly ash t o improve the compressive strength of concrete but concrete strength back down on substilution 10% and 15% Jly ash. Testing is carried out by comparing the compressive strength of the rebound hammer t es t, UPV and compressive strength machine.
