How to Calculate Quantities of Cement, Sand and Aggregate for Nominal Concrete Mix (1:2:4)? Mix design is a process of determining the right quality materials and their relative proportions to prepare concrete of desired properties like workability, strength, setting time and durability.
In dry-mix applications, all dry materials – including cement, aggregate, and ad-mixture – are mixed together, conveyed pneumatically through a hose and then, at the nozzle via a water ring, water is injected evenly throughout the mix as it is being projected.

Concrete Mixes. Concrete mix is a blend of portland cement, gravel and sand. When those main ingredients are proportioned correctly the result is a durable and high-quality surface that will last for many years. Ingredients required to create a concrete mix can be delivered and blended on site. This is commonly referred to as field mixing.

The reference concrete mix or accelerated strength of concrete mix has w/c ratio as 0.35 and workability very low with slump 0 to 10 or compacting factor 0.8 with the available cement i.e. (cement in hand). The nominal maximum size of natural crushed aggregate should be 10 mm and fine aggregate should conform to zone II of table 4 of IS-383-1970.

That said, shown to the right and below are two perfect precast concrete mix designs. Mix 1 is a traditional mix that typically is used in larger products with normal weight material, while Mix 2 is an accelerated self-consolidating concrete mix that is used in smaller products with tight form spacing (2-inch-wide walls) and no reinforcing. Mix 1
Looking at consistency – concrete is mixed to a wetter consistency while the screed mix should be of a semi-dry, non-crumbly consistency. For concrete, the slump rates depend on the application and mix design. Being a wetter mix, concrete is usually applied using floats or piston pumps, whereas the semi dry screeds are installed using ...
Mixing Concrete . When it comes to mixing concrete, there are three options to choose from: Mix by hand - where less than ¼m³ of concrete is needed, it can be mixed by hand by a reasonably fit person. Use a cement mixer - where the quantity is between about ¼m³ and 2m³, a powered concrete mixer is useful or
For the concrete with undemanding performance nominal or standard mixes (prescribed in the codes by quantities of dry ingredients per cubic meter and by slump) may be used only for very small jobs, when the 28-day strength of concrete does not exceed 30 N/mm2.
