The most common raw rock types used in cement production are: Limestone (supplies the bulk of the lime) Clay, marl or shale (supplies the bulk of the silica, alumina and ferric oxide) Other supplementary materials such as sand, fly ash/pulverised fuel ash (PFA), or ironstone to achieve the desired bulk composition.

 · Mix Design Mix design mainly depends on the strength required & quality of material available. The main ingredients in manufacturing solid concrete blocks are: 1) Cement 2) Fly ash 3) Crushed sand (0-3mm) 4) Aggregates (5-10mm) Typical mix design for solid concrete blocks is given below, Mix design for block grade –7.5 Mpa (target strength)

 · 2.1 Raw material for cement Minerals of natural origin as well as industrial products can be used for the production of cement. Starting materials for this purpose are mineral compounds, containing the main components of cement, lime, silica, alumina, and iron oxide. The two main components are generally limestone and clay. In cement raw materials.

This paper focuses on modelling and solving the ingredient ratio optimization problem in cement raw material blending process. A general nonlinear time-varying (G-NLTV) model is established for cement raw material blending process via considering chemical composition, feed flow fluctuation, and various craft and production constraints. Different objective functions are …

 · Concrete Mix Design with Portland Pozzolana Cements. The Indian standard IS:456-2000 recommends the use of Portland pozzolana cement (blended cement) as well as mineral admixtures for concrete mixes provided that there are satisfactory data on their suitability, such as performance test on concrete containing them.
