| Abstract | The purpose of this paper is to investigate whether the coal bottom ash has a reaction as pozzolanic material after grinded, and whether its chemical and physical properties can meet the specification of CNS 3036: fly ash for concrete and natural or smoldering pozzolanic material, and whether it can be used for concrete. In this study, the coal bottom ash of Linkou was grinded by a ball mill. After grinding, the remaining amount of the sieve was only 0.5%, which was much lower than the standard requirement of 34%. The chemical properties of the bottom ash are similar to those of fly ash, and match the specification of the type of F-class fly ash. The slurry flow test was carried out on the bottom ash after grinding, and it was found that the fluidity was not good, mainly the non-spherical particle powder after grinding. There is no bearing lubrication, so the fluidity was poor. The 25% of air-selected coarse fly ash is mixed with the 75% of grinded bottom ash found that has a lower water needed and its activity can still reach 104.8%, which is better than 96.8% of fly ash. Thus, the results show that the bottom ash after grinded are superior to traditional fly ash. The results of this study show that the bottom ash should be applied to concrete related materials after grinding, which is beneficial to the reduction of coal bottom ash. |
