The ratio of cement, sand and crushed stone in M 25 grade concrete is 1:1:2.In this grade of concrete a compressive strength not less than 25 N/mm2 is achieved in 28 days.
A lean mix simply means that there is more liquid that concrete in the mix. The mix is thin and pours easier. It is sometimes used when you need to make a base on an uneven surface, like dirt. You would pour the lean mix, and then use it to put the more solid mix on top of.

To calculate the amount of sand and metal (aggregate) in M10 and M20 grades of concrete, you first need to determine the mix ratio. M10 is typically a 1:3:6 ratio (cement:sand:aggregate) and M20 is a 1:1.5:3 ratio. For a given volume of concrete, calculate the total parts in the mix, then divide the total volume by the sum of the parts to find the volume of each component. Finally, multiply the volume of sand and aggregate by their respective mix ratios to find the quantities needed.
The strength of concrete depends on the mix used to make it- ratio of cement, sand, gravel and water. If the mix does not produce a concrete that is strong enough, the concrete will break.

The Concrete mixing ratio for M35 grade concrete as per IS Mix design is1:1.6:2.907 (cement:Fineaggregate:Coarse aggregate)The ratio obtained is as per design calculations by considering the grade of aggregates and the type of cement used.The Water/cement ration is 0.43
cemet: sand: Agg=1:1:2 (Nominal Mix) Above answer is not as per engineering standards. For concrete mixing ration in M30 grade concrete, the mix has to be designed after testing all the materials including water in labs. When you go for higher grade of concretes the mix has to be designed , it is the water to cement ratio which has to be monitered for higher grades of concrete
To determine how many 50 kg cement bags are required for 1 cubic meter of Grade 30 concrete, we need to break down the mix ratio and calculate the cement content based on that. Grade 30 Concrete Mix Ratio Grade 30 concrete typically has a mix ratio of 1:2:3 (Cement: Sand: Aggregate) by volume. This means: 1 part cement 2 parts sand 3 parts aggregate (gravel) However, the actual proportion of cement required can vary slightly depending on the specific mix design used by a contractor or engineer. For standard Grade 30 concrete, the cement content is typically around 350 to 400 kg per cubic meter. Since each cement bag weighs 50 kg, the number of bags required for 1 cubic meter of Grade 30 concrete would be: Number of bags = 350 kg / 50 kg = 7 bags

The ideal cement and sand mix ratio for optimal strength in a concrete mixture is typically 1 part cement to 3 parts sand. This ratio helps ensure a strong and durable concrete mix.
Why does concrete mix with low water cement ratio resulted in hardened concrete having higher strength than those with high water cement ratio?
1:1.5:2.5
The recommended mortar mix for concrete blocks is a 1:3 ratio of cement to sand.
A lean mix simply means that there is more liquid that concrete in the mix. The mix is thin and pours easier. It is sometimes used when you need to make a base on an uneven surface, like dirt. You would pour the lean mix, and then use it to put the more solid mix on top of.
