For this, the ratio should be (1:3) 1 part cement to 3 parts sand, or (1:1:1 or 1:1:2) 1 part cement, 1 part sand, and 1 or 2 parts aggregates. Remember, for maximum strength in the resulting concrete, always use the least amount of water that still allows for good fluidity.
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 is made from cement, sand, gravel and water. In making concrete strong, these ingredients should usually be mixed in a ratio of 1:2:3:0.5 to achieve maximum strength. That is 1 part cement, 2 parts sand, 3 parts gravel, and 0.5 part water.
Concrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume
Westend61/Westend61/Getty Images. The basic mix ratio for concrete is one part water, two parts cement and three parts sand. An alternative ratio is one part cement, two parts sand and three parts gravel with enough water added until the mixtures reaches the consistency of thick mud. Lime is also a common additive to the mix.
A concrete mix ratio is usually expressed by a set of numbers separated by colons, as is the case with a 1:2:3 ratio. This tells the mixer that they need to add 1 part cement powder, 2 parts sand, and 3 parts aggregate in order to create the desired concrete consistency. Water is not included in these ratios, though, because it can vary more ...
When producing concrete it's necessary to use the correct concrete mixing ratios to make a strong, strong concrete mix. Some necessary mixing ratios for concrete are 1:2:3, 1:3:3, 1:2:4. These mixing ratios are based on the relationships of cement : sand : stones in that law. The ratio you do will depend on what psi power you require.

Firstly, the water-cement ratio required to obtain the desired concrete firmness is calculated. Secondly, the water demand of concrete mix and the ratio of filling the empty space between the gravel grains by sand and cement paste is determined considering desired mobility level of the mixture.
A concrete mixture was made of cement, chips and sand. The ratio of the cement and chip is the same as that of chips and the sand. asked Mar 5, 2020 in Commercial Mathematics by Sunil01 ( 67.6k points)
A bag of 40kg cement yields about 0.98 cubic feet volume, regarding this, How much sand and gravel do I need for a bag of 40kg cement, generally you will need about 1.96 cubic feet of sand and 3.92 cubic feet of gravel per 40kg bag of cement by using mix ratio 4 parts gravel to 2 parts sand to 1 parts cement (4:2:1) for 3000 psi or 20 MPa of ...
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.
Investigation of the Effect of Aggregate/Cement and Water/Cement Ratios on Concrete WorkabilityView Book :- https://stm.bookpi.org/NVST-V6/article/view/4128#...
M25 concrete ratio:-M stand for mix and numerical figure 25 is compressive strength of concrete is 25N/mm2 for curing time of 28 days and M25 concrete ratio is 1 : 1 : 2, mixture of cement, sand and aggregate in which one part is cement, 1 part is sand and 2 part is aggregate or stone mix with water.
Coarse Aggregate Quantity-(Coarse Aggregate parts / Sum of Concrete parts) x Concrete Volume -(3/5.5) x 5 =2.7272m3 Water Quantity – W/C Ratio x Cement Volume Note – 0.45 is an assumed water cement ratio according to IS 10262 (2009)
The closer you bring the ratio to an even one-to-one of sand to cement, the stronger the rating becomes. This principles works in the opposite direction as well. If you want to get a little more technical, some concrete experts recommend going for 26 percent sand, 41 percent gravel, 11 percent cement and 16 percent water.
Concrete mix ratio is a relative proportioning of cement, sand, aggregate and other materials needed to prepare different grades of concrete. For example, the prescribed Nominal concrete mix ratio of M20 concrete is 1:1.5:3, hence for every 1 part of cement, 1.5 parts of sand and 3 parts of aggregate, in volume, is needed to prepare M20 grade ...

So that by decrease in water to cement ratio from 70% to 20%, the concrete electrical resistivity increases up to 303% and 293% for concrete specimens containing cement types 5 and 2, respectively. In fact this issue shows that reduction in water to cement ratio causes increase in resistance against corrosion and enhances concrete durability.
Answer (1 of 20): Concrete Mix for Foundation, Pillar, Beam and Slabs. There are two method adopted for mixing Cement, Sand and aggregate . One is based on the Volume of materials Other one is based on the Weight of Materials . Volume Batching (1) M15 grade Concrete: 1:2:4 is the ratio of Ceme...
Total Aggregate by cement ratio (A/C) decreases with increase in grade of concrete. For example, M20 grade of aggregate will have a higher A/C ratio than of M30. Higher the Aggregate/Cement ratio leaner the concrete mix, as cement content is lower. Concrete mix can be made more workable by fine tuning Aggregate/Cement ratio.
