| Outline of Final Research Achievements |
The present study shows that an equivalent factor (k-value) of fly ash, which indicates the contribution of fly ash as cementitious material to the strength development of mortar or concrete, can vary with the replacement ratio of fly ash. The k-vale was investigated by composition of cementitious material in order to design a mix proportion of fly ash concrete by evaluating water to cement ratio with k-value. As a result, the k-value can be evaluated by the amount ratio of SiO2 in fly ash to C3S and C2S in cement. In addition, the performance of fly ash can be improved by curing internally.
