gen 3 concrete mix cement content

One of the best concrete mix ratios is 1 part cement, 3 parts sand, and 3 parts aggregate, this will produce approximately a 3000 psi concrete mix. The strength of this mix ratio is good for most concrete slabs, footings, steps, and foundation walls.

Concrete should be mixed using an appropriate method to achieve the required strength and durability. Except for very small quantities, a mechanical mixer should be used. Where hand mixing, add an extra 10% of cement to the quantities shown in Tables 2 and 3.

Nominal mix ratios for concrete are 1:2:4 for M15, 1:1.5:3 for M20 etc. Standard Mixes or Ratio. The nominal mixes of fixed cement-aggregate ratio (by volume) vary widely in strength and may result in under or over-rich mixes.

Most concrete mix designs use the same type of raw materials: cement, water and C20 concrete mix and Gen 3 concrete is commonly used for lightweight 

3. The proportion of various ingredients of concrete made in batch mixing of the cement content in concrete can be substituted with fly ash without sacrificing

The mix ratio of 1:2:3 consists of 1 Part cement, 2 Parts sand, and 3 Parts stone (plus some water) to make a concrete mix you can use for most any building project. The way you measure the ratio could be in shovels, buckets, or wheel barrows.

One, proper mix proportions using the optimum cement content will yield a dense, impervious and relatively unabsorbent concrete. Two, the optimum concrete is 6 and one half to 7 and one half sacks per cubic yard and the water/cement ratio should not exceed 6 gallons per sack of cement to produce a mix that is plastic and workable.
