• Abstract:
  In the last half century much research has been conducted to find an acceptable cement substitute; the ; most intriguing and interesting of those materials is fly ash. Fly ash consists of almost perfectly spherical ; particles that are rich in calcium, silicon, iron and aluminum. ; The report outlines preliminary work on several novel particle analysis techniques used to investigate ; fly ash. Also included is a series of physical tests used to investigate the strength, performance in alkali silica ; reaction, and chloride penetration of fly ash. Although more work is needed to make strong findings, the ; particle analysis techniques were able to find differences in these materials when bulk analysis could not. ; These findings are critical to better elucidating the difference in performance in these materials.
