| 要旨 | This paper aims at investigating the contribution of fly ash to strength development of concrete by evaluating the relationship between cementing efficiency factor k (k-value) and degree of fly ash reaction. The compressive strength of concretes was examined and the degree of fly ash reaction in paste specimens was measured by selective dissolution method at the ages of 7, 28 and 91 days. The results showed that the k-value of fly ash increased proportionally with an increase in the degree of fly ash reaction for each mixture proportion. |
