| Research Abstract |
In this study, mix design theory for large quantity use of coal ash in the shape of slurry into concrete was discussed.
1.It was certified that large quantity use of superplasticizer is not required by our method. The period of stabilization of coal ash slurry was shown.
2.The formula that was presented for the concrete containing coal ash with constant Portland cement content was shown to be applicable to the concrete containing coal ash with constant powder content. Next, the new method and its formula for the concrete that always performed the same compressive strength to the Portland cement only concrete with the appropriate combination of the cement and coal ash content were shown.
3.Concrete containing large quantity of coal Ash was easily produced in ready-mixed concrete plant
