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.
Generally its 1:1:2
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.
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.
The binder in concrete is usually cement. Cement causes the aggregate and sand to bind together mechanically and harden to make a solid surface.
Aggregate, Ordinary Portland Cement, sand, water
Ration used in M10 concrete is 1:3:6 1 Cement, 3 Sand & 6 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.
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.

No. Concrete is a man-made material composed broadly of cement, sand and aggregate (crushed rock).
Concrete mix is made from (sharp)sand, cement, aggregate and water. The ratios depent on the usage
concrete c35 - 1:1,5:2,5 (cement,sand,aggregate)
Yes. The cement used to make concrete usually has sand, aggregate and Portland cement in it. That would make it heterogeneous.
