摘要：

Determining　the　content　of　fly　ash　(FA)　in　hardened　cement　concrete　is　very　difficult　at　present.　In　this　paper,　samples　were　prepared　with　water/binder　ratio　(0.4),　different　FA/binder　ratios　and　different　curing　ages,　the　backscattered　electron　imaging　and　image　analysis　technology　are　used　to　study　the　dosage　of　FA　in　the　hardened　cement　mortar.　The　results　show　that　the　backscattered　electron　imaging　and　image　analysis　technology　can　comparable　accurately　test　the　dosage　of　FA　in　hardened　cement　mortar;　this　method　doesn＇t　need　to　know　the　chemical　composition　of　raw　materials　or　prepare　the　standard　reference　samples.　©　2016　Trans　Tech　Publications,　Switzerland.
