contact us1. Nominal Concrete Mix Ratios. The specifications for concrete prescribed these proportions of cement, sand, aggregates, and water. These mixes of the fixed cement, sand, and aggregate ratio that ensures adequate strength are termed nominal mixes. Nominal concrete mixes offer simplicity and under normal circumstances, have a margin of strength above that specified.

contact usA basic mixture of mortar can be made using the volume proportions of 1 water : 2 cement : 3 sand. Most of the student activities can be conducted using this basic mixture. Another "old rule of thumb" for mixing concrete is 1 cement: 2 sand: 3 gravel by volume. Mix the dry ingredients and slowly add water until the concrete is workable.

contact us· Today we will discuss how to calculate quantities of materials for different mix ratio of concrete. (Dry mix method) We will calculate quantities of materials for 1 m3 concrete (By volume). Let us assume the mix proportion is 1 : 2: 4 (cement:sand:stone =a:b:c) Volume of wet concrete = 1 m3. Volume of dry concrete = 1 × 1.54 = 1.54 m3.

contact us· To make ease in understanding we are finding the Concrete mix design of M20 grade concrete. The Concrete mix ratio for M20 grade of concrete is 1:1.5:3 that mean 1 part of cement, 1.5 part of sand (fine aggregate) and 3 parts of aggregate (crushed stone) in volume and then batched for mixing. To know the Concrete Mix Design follow below:-.
