| Abstract: |
| High strength composite Portland cement made of a large amount of blast furnace slag, fly ash and limestone was obtained. The effects of grinding method, gypsum kinds and amounts, and additions as well as mix proportion of slag and fly ash on the properties of the composite Portland cement were studied and its concretes were tested. Hydration heat, hydration phases were investigated by means of micro-calorimeter, XRD, DTA and SEM. |
