A-4)Estimation of mixing water a) Weight of water for 20 mm aggregates and slump 25-50 mm = 186 litre. b) Weight of water for 50-75 mm slump (increased by 3% for additional 25 mm slump as per is 10262 clause 4.2) = 191.58 litre.
Here, "M" denotes the mix ratio of concrete and numerical value shows the value of grade of concrete. For example, If we take the M20 grade of concrete then, M shows that it has a mixture of cement, sand, and aggregate in 1:2:3 in proportion. And 20 shows that the compressive strength of concrete is 20 KN/ mm2.

This paste is also called as concrete. The strength of this concrete mix is determined by the proportion on which these cement, sand, stones or aggregates are mixed. There are various grades of concrete available in the market based on these ratios. Some of them are: M10, M20, M30, M35, etc. So, what really does M10 or M20 mean or represent.

This concrete mix ratio of aggregate to sand to cement is an important factor in determining the compressive strength of the concrete mixture. This concrete mixture ratio of 1 part cement, 1 parts sand, and 3 parts aggregate will produce a concrete mix of approximately 2500 to 3000 psi. Mixing water with this cement, sand, and aggregate will ...

Concrete mix of grades M10, M15, M20, and M25 closely match the nominal mix proportions of 1:3:6, 1:2:4, 1:1.5:3, and 1:1:2, respectively. 3. Design Mix of Concrete Ratio. In this mix of concrete, the performance of concrete is stated by the designer but the mix ratios are determined by the producer of concrete.
These mixes of the fixed cement-aggregate ratio which ensures adequate strength are termed nominal mixes. B. IS 456-2000 has designated concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35, and M40.

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:-.
Concrete Mix Ratio by Volume The volumetric mix ratio of M20 concrete is 1:1.5:3, hence 1 part of cement, 1.5 part of sand and 3 part of aggregate in volume is needed to prepare M20 grade concrete.

Weight of 1 cubic meter of M20 concrete. We have to prepare 1m3 of M20 concrete, this is wet volume, to calculate dry volume we will multiply 1.54 in wet volume, so total volume of concrete = 1.54m3, in M20 concrete nominal mix ratio of cement, sand and aggregate is 1: 1.5: 3 respectively and water cement ratio is about 0.55.
The water ratio seems to be 1 kg cement to 0.5 liter of water to get a good hydration but for the mix I have now got a few options, 1 - 2 - 2 or 1 - 2 - 4. or even 1 - 1.5 - 2.5 . I don't have a vibrating poker and was wondering what manual alternatives there are …
