about cement manufacturing and calculation of cement

Calculation of Cost for 1m 3 of Concrete. Let's consider the concrete mix of M15 (1:1.5:3), where, 1 is the part of cement, 1.5 is the part of fine aggregates and 3 is the part of coarse aggregates of maximum size of 20mm. The water-cement ratio required for mixing of concrete is taken as 0.45. 1. Assumptions:

  • How Concrete is Made  Portland Cement Association

    How Concrete is Made Portland Cement Association

    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 rock-like mass known as concrete.
