This study was conducted to determine the strength of concrete containing coal bottom ash (CBA) as cement replacement material. The original CBA were sieved passing 150 um sieve size then ground for 20, 30, and 40 hours using ball mill machine. The normal concrete were designed for grade 30 based on...
