Normal grade of concrete are based on nominal mix ratio of cement, sand and aggregate have comparatively lower compressive strength than standard grade of concrete. Normal grade of concrete are M25,M20,M15,M10,M7.5 & M5 generally based on nominal mix proportion of cement sand and aggregate.
There are two main ways to design the concrete mix. Design mix method :- In this method, materials are proportioned based on the procedure and rules given in IS 456 (2000) and IS 10262) code . In this method, cement, sand and aggregates are always batched in terms of weight, and concrete can be designed for different environmental conditions and different needs.
Dec 08, 2017· 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.
Concrete vibrated by efficient mechanical vibrators require less water cement ratio, and hence have more strength. Thumb Rules for deciding the quantity of water in concrete: (i) Weight of water = 28% of the weight of cement + 4% of the weight of total aggregate (ii) Weight of water = 30% of the weight of cement + 5% of the weight of total ...
The strength of the concrete greatly depends on the density of the concrete hence we should not play with the ratio of sand to aggregate. I would suggest the ratio of 1:2:3 or 1:1.5:3 for M20 grade concrete and 1:2:4 or 1:2.5:3.5 for M15 grade concrete. If you prepare concrete with your ration then the concrete will have too much sand.

Sand Volume – 0.423 m 3. Coarse Aggregate – 0.845 m 3. Water Cement Ratio Calculation. From the IS Code standard, Assuming the water-cement ratio for M20 is 0.55. Therefore required water quantity = Cement Volume X WC Ratio = 0.282 X 0.55 = 0.1551 m 3 Unit weight of water = 1000 Litres / m 3 Water Quantity in Litres = 155.1 Litres
The ratio of fine aggregate to coarse aggregate to be used in concrete is 1:2, which means that for every 1 part of sand we have to take 2 part of gravel. Hence we have to divide the Total Aggregate into 3 parts and take 1 part as sand and 2 parts as coarse aggregate. Lets calculate weight of sand and gravel needed for M15 Grade concrete.
Concrete grades are denoted by M10, M20, M30 according to their compressive strength. The "M" denotes Mix design of concrete followed by the compressive strength number in N/mm 2 "Mix" is the respective ingredient proportions which are Cement: Sand: Aggregate Or Cement: Fine Aggregate: Coarse Aggregate.
5.a. Approximate sand and water contents per cu.m of concrete W/C = 0.6, Workability = 0.8 C.F. (For medium strength concrete up to M35) Maximum size of aggregate (mm) Water content including surface water per m³ of concrete (kg) Sand as % of total aggregate by absolute volume 10 …
grade M10 = 1 : 3 : 6 ratio sum = 1+3+6 =10 let volume of concrete = 1 cubic meter(wet volume) therefore dry volume of concrete= 45% to 55% increase in volume x wet volume dry volume = 1 x 1.54(assuming 54% increase in volume) dry volume = 1.54 * ...
Dec 14, 2019· Normal grades of concrete . a. M5 Grade ~ Mixing Ratio is 1:5:10 ( 1 part of cement, 5 parts of sand and 10 parts of aggregate). ~ Compressive strength is 5MPa. ~ Used in foundation bed to prevent direct contact between soil and foundation concrete. b. M7.5 Grade ~ Mixing Ratio is 1:4:8 ( 1cement part: 4 sand part: 8 aggregate part).
Concrete Mix Formula. Example: M 15 mixing concrete ratio of Concrete (1:2:4) here (1 no of Cement quantity, 2 nos of Send quantity, 4 nos of Aggregate quantity, Here quantity measured by mixing box) it also called recipes for concrete. E.g., M15(1:2:4), the quantity of cement, sand (fine aggregate), and coarse aggregate are batched in volume as per the fixed ratio 1:2:4.
Concrete grades are denoted by M10, M20, M30 according to their compressive strength. The "M" denotes Mix design of concrete followed by the compressive strength number in N/mm 2 "Mix" is the respective ingredient proportions which are Cement: Sand: Aggregate Or Cement: Fine Aggregate: Coarse Aggregate.
Example calculation Estimate the quantity of cement, sand and stone aggregate required for 1 cubic meter of 1:2:4 concrete mix. Ans. Materials required are 7 nos. of 50 kg bag of cement, 0.42 m 3 of sand and 0.83 m 3 of stone aggregate.
The mix ratio is 1:4:8 (1 Cement, 4 Sand and 8 Aggregate) Application/use: – To provide the uniform surface of the foundation concrete and to prevent the direct contact of foundation concrete from the soil. 2- Ordinary grade of concrete. M10 GRADE. The mix ratio is 1:3:6 (1 Cement, 3 Sand and 6 Aggregate) It is used as PCC (Plain Cement Concrete)
Calculate Cement Sand Aggregate – M20, M15, Concrete mix ratios are prescribed ratio of cement, sand and aggregate to get the desired strength in concrete. 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 Coarse Aggregates = 0.84 x 1520 = 1276.8 kg (1.28 tonnes) The above calculation you can use for all Grade of Concrete but just you have to put the different Grade of concrete like M10, M 15, M20, M25 etc. just here with grade of concrete you can change the proportion and the method is just above which I have discuss .

To make ease in understanding we are finding the Concrete mix design of M20 grade concrete. 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.
The ratio of fine aggregate to coarse aggregate to be used in concrete is 1:2, which means that for every 1 part of sand we have to take 2 part of gravel. Hence we have to divide the Total Aggregate into 3 parts and take 1 part as sand and 2 parts as coarse aggregate. Lets calculate weight of sand and gravel needed for M15 Grade concrete.
