M Sand Manufacturing Process The hard rocks are blasted into medium-sized stones, and those stones are transported to the plant. Then the stones are washed and cleaned from dust & other impurities. The cleaned stones are placed into the primary crusher to crush the rocks into 40mm aggregates.
· Process Capability Index: Cp and Cpk Process capability – Cp : This is defined as the tolerance width divided by the total spread of process (6 Sigma). Cp indicates the spread of variation present in a process. Process Capability Index – Cpk: This is the capability index that accounts for the centering of the process and is defined as the minimum of Cpk upper and Cpk lower.
· Casting is a manufacturing process in which molten metal is poured into a specially designed cavity. When metal cools down and becomes solid it takes the shape of cavity. This cooled solid metal is called casting. After this we take out that casting of desired shape and size from the cavity. We can further do some work in this casting to make ...

Thus, the quantity of cement required for 1 cubic meter of concrete = 0.98/0.1345 = 7.29 bags of cement. The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg.
