There is a large of CMA biomass ash in china every year, which not only occupies farmland and pollute environment but also impact the development of farming and animal husbandry. Therefore, it is necessary to study to reuse CMA biomass ash in concrete to replace concrete. In this paper, status of research of the CMA application in concrete at home and abroad is analyzed, the problems of the present research which exist in application of CMA biomass ash in concrete and how the particle size of CMA influence the performance of concrete when some cement is replaced by CMA is points out. It is necessary to carry out to study how particle size of CMA biomass ash influence on concrete performance.
