Abstract Details

2019, Master of Science, Ohio State University, Civil Engineering.
The objective of this study was to examine the influence of the bulk chemical composition of fly ash on the compressive strength of concrete. Results from the compressive strength tests of 181 concrete samples that used partial cement replacement with fly ash were used as data to create multiple linear regression models. These models were compared to a baseline model to predict the compressive strength of concrete based on bulk composition of the fly ash. Both statistical and experimental methods were used for verification. This study found that the new Selected model measuring w/c ratio, w/c ratio, LOI, and the bulk percentage of six metal oxides, was better able to predict concrete 28-day strength. It finds that the current ASTM limits for fly ash are insufficient to fully explain the strength of concrete utilizing fly ash and that a better set of measurements is needed to determine if a fly ash is acceptable for use in concrete for structural applications.
