The ratios of cement to sand to aggregate for the different grades of concrete are as follows. M10 has a ratio of 1:3:6. M15 has a ratio of 1:2:4. M20 has a ratio of 1:1.5:3. M25 has a ratio of 1:1:2, but M30 has no set ratio. It is a designed mixture to achieve the stress tolerance desired.
For M7.5 concrete, the common mix ratio is 1:4:8. This means:1 part cement 4 parts fine aggregates (sand)8 parts coarse aggregates. These ratio is by volume.
To determine how many bags of cement, sand, and aggregate you need, you'll first need to know the specific mix ratio for your project (e.g., for concrete, a common mix is 1:2:3, which means 1 part cement, 2 parts sand, and 3 parts aggregate). Then, calculate the total volume of concrete needed and convert that into the respective volumes of each material based on the mix ratio. Finally, divide the volume of each material by the volume contained in a standard bag (usually 94 pounds for cement) and the bulk density for sand and aggregate to get the number of bags required.
RCC that is reinforced cement concrete which is composed of cement(mainly),sand(fine aggregate),metal(coarse aggregate)and water.Which is further more supported by iron which makes it RCC from ordinary cement concrete.
Mix ratio for M5 concrete is 1:1.5:3compressive strength is 20N/mm2 @ 28 days.1 part of cement, 1.5 part of sand, 3 parts of coarse aggregate.
Choose the grade of concrete & assume minimum water/cement ratio.Conduct some initial tests on the materials like cement, sand & metal(coarse aggregate).Tests like UNIT WEGHT, SPECIFIC GRAVITY,SIEVE ANALYSIS,SLUMP CONE TEST & COMPACTION FACTOR TEST. According to the obtained results do the mix design from IS CODE of IS800-10262 check for water cement ratio & calculate the quantity of cement, sand & coarse aggregate.

Concrete is what you make a sidewalk from. To make concrete, you mix Portland cement, sand, gravel (aggregate) and water. The cement holds the aggregate together.
For M7.5 concrete, the common mix ratio is 1:4:8. This means:1 part cement 4 parts fine aggregates (sand)8 parts coarse aggregates. These ratio is by volume.

The ideal ratio for a sand and cement mix for a strong and durable concrete foundation is typically 3 parts sand to 1 part cement.
Concrete is a composite construction material, composed of cement (commonly Portland cement) and other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate made of gravel or crushed rocks such as limestone, or granite, plus a fine aggregate such as sand), water and chemical admixtures.
Formula of concrete ratio 1:2:4 means 1 part of cement, 2 parts of fine aggregate(sand) and 3 parts of coarse aggregate(gravel). Other examples of command concrete mixture ratio are 1:3:6 , 1:1.5:3 and 1:4:8. Water use in concrete mixture is based on water/cement ratio, for example 0.5 or 0.6.
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.
