| Abstract: | The surface modification mechanism of fly ash is presented. Modified fly ash materials were manufactured by means of local activation and grinding aid and disperse according to technology of physical chemistry such as adding Calcium and Silicon, alkali activity and milling. Activation hypostasis and application foreground of modified fly ash were opened out through the study on its physical index, grain shape, particle size distribution and using in concrete . |
