Proper calculation and relative proportioning of materials are important to produce a good quality concrete. Let's see some simple techniques used by engineers to calculate cement, sand, coarse aggregate (gravel or Jalli) and water needed to produce different grades of concrete, like M5, M7.5, M10, M15 and M20.
The Construction and Design of Concrete Slabs on Grade D. Matthew Stuart, P.E., S.E., F.ASCE, SECB COURSE CONTENT Slab on Grades Construction: Introduction Concrete slabs on grade are a very common type of concrete construction. Floor slabs can range from a simple residential basement slab to a heavy-duty industrial floor.
In Mineral Processing Design and Operations (Second Edition), 2016. 6.2.3 Roll crusher circuit design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as chalcocite and chalcopyrite, they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size.

though mixer design begins with a focus on process requirements, the mechanical design is essential for successful operation. Usually, a competent manufacturer of mixing equipment will take responsibility for the mechanical design. However, process conditions, such as impeller operation near a liquid surface, can impose severe mechanical loads.
(Marsh, 1997) design of normal concrete mixes Calculate the water cement ratio For a particular cement and aggregate type, the concrete strength at a given age is assumed to be governed by the free water: cement ratio only. The first step is to obtain a value of strength at water: cement ratio of 0.5 according to the 1988 British method.

concrete strength fc' from 3000 psi to 10,000 psi. The graph is not intended for precise evaluation of member capacity, as precise strength values are given in other design aids. Rather, the graphs clearly show stress ranges for which design requirements change. No shear reinforcement (stirrups) are required if Vn/(bwd) is less than 1.0√fc'.
