EVALUATION OF EXPERIMENTAL EVALUATION OF FLY ASH CONCRETE IN LOUISA

The objective of this study was to investigate the resistance of field concretes containing fly ash to damage from cycles of freezing and thawing as evidenced by scaling, based upon a reevaluation of a field project. In 1955 and 1956 an experimental sidewalk, curb and gutter installation made from concrete utilizing fly ash was placed in Louisa. In one mixture 20% of the cement by weight was replaced with fly ash and in another 33% of the cement was replaced. Air contents were approximately the same. A visual examination of the installation revealed that concretes containing fly ash exhibited more scaling than did the control mixture, with the mixture having the 33% replacement scaling the most. The internal structures of cores taken from all concretes (20% replacement, 33% replacement and the control) were in good condition and no internal damage from freezing and thawing could be observed. The compressive strengths of the cores were all satisfactory.
