    200561 It is necessary to establish the material design system for the utilization of large amounts of fly ash as blended cement instead of disposing of it as a waste. Cement blended Effects of sulfates on the hydration of Portland cement A ,412 The fineness of cement has a significant influence on sulfate demand. Increasing the C 3 A fineness increases the ettringite formation [6]. Increasing the C 3 S fineness results in flash animation hydration of cement razoriteolivedale.co.za,How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rocklike mass known as concrete.
