งานวิจัยนี้ศึกษาการซ่อมแซมความเสียห

This research studies the repair of concrete column damage with ultra-high performance concrete using kiln bottom ash. and fly ash is ground and mixed with cement. The test was conducted using cylindrical concrete that had been cured for 28 days and then burned to simulate the event that concrete would be heated by a fire. It takes 2 hours to burn at a temperature of 600 degrees Celsius.

This study investigated the use of ultra-high performance concrete mixed with furnace bottom ash and fly ash with cement to repair damage to concrete columns. Testing was conducted using cylindrical concrete that has been cured for 28 days. And burn it to simulate the event of concrete being heated by a fire, which takes 2 hours to burn at 600 degrees Celsius.

In this paper, the damage repair of concrete columns with ultra-high performance concrete crushed by fly ash, fly ash and cement was studied. In the experiment, cylindrical concrete was cured for 28 days and sintered at 600°C for 2 hours to simulate the fire incident of concrete.
