Grinding process is introduced to provide fine particles of coal fly ash that enhances the strength gain of cement mortars. It is discovered that grinding can make all the studied fly ashes more suitable for concrete use at higher replacement value than previously anticipated even when the effect of high carbon content is considered.

Other raw materials, such as mill scale, shale, bauxite and fly ash, are brought in from outside sources when necessary. Rock blasted from the quarry face is transported to the primary crusher, where chair sized rocks are broken into pieces the size of baseballs. Some plants will use a secondary crusher, depending on process needs.

most difficult to process. Grinding Grinding fly ash has been found to enhance reactivity by increasing surface area, whilst at the same time increasing the water demand of fly ash. The water demand effect is due to the breaking down of the spherical fly ash particles that give the material its ‘ball-bearing’ effect and help to reduce the water
