| Research Abstract |
In this present study, has been advanced aiming to improve the activation level from the viewpoint that expands effective use for fly ash (hereafter, FA), and to make it to an alternative material of ordinary portland cement. The following finding was obtained from a series of outcome of an experiment. (1) In the condition whose replacement ratio of FA is 25%, if FA is fine ground and NaOH is added in the proper quantity, compressive strength equal with cement is usually obtained. (2) CaSO4 (2H2O) is an additive that obtains the ameliorating effect of an extremely excellent activation level in the condition with extremely large replacement ratio of FA. (3) Under the condition with the admixture, by the addition of NaOH and fine ground FA, improvement of excellent activity is obtained
