Calculate Cement Sand & Aggregate from Concrete Mix Ratios – M20, M15, M10, M5

Mar 12, 2016

—

Understanding the correct calculating methodology and knowing the precise quantity of materials is important to achieve the proper relative proportion of cement, sand, aggregate, and water for producing high-quality concrete. This comprehensive article offers straightforward methods to determine the exact amounts of cement, sand, aggregate, and water needed to attain different concrete grades, including M5, M7.5, M10, M15, and M20.

Elevate the quality of your concrete projects with our expert insights, empowering you to confidently create exceptional structures. Our calculations have been verified against respected standards like IS456, IS10262, and the government’s “Rate of Analysis,” ensuring reliability and accuracy.

Understanding Concrete Grades:

Concrete grades are named according to their strength and performance. The letter “M” in the grade stands for “mix,” and the number after “M” represents the expected compressive strength after 28 days of water curing. Some commonly used Nominal Mix grades are M5, M7.5, M10, M15, and M20.

To illustrate, let’s consider M20 grade concrete. After undergoing 28 days of water curing, this particular grade will possess a compressive strength of 20 N/mm2. The compressive strength is a crucial parameter that determines the durability and load-bearing capacity of the concrete.

Concrete Mix Ratio Explained:

Concrete mix ratio refers to the specific proportions of cement, sand, aggregate, and other components required to create different concrete grades. The nominal mix ratio for M20 Concrete, for instance, is 1:1.5:3. This means that for each part of cement, 1.5 parts of sand and 3 parts of aggregate are necessary to produce M20 grade concrete.

Difference Between Nominal Mix Ratio and Design Mix Ratio:

Nominal mix ratios are predetermined volumetric ratios suitable for on-site concrete mixing, while Design mix ratios are calculated weight ratios utilized for large-scale production in RMC plants or laboratories.

Nominal mixes are convenient for preparing smaller to medium quantities of concrete, whereas Design mixes follow the IS10262 codebook guidelines for precise mix proportions.

Nominal Concrete Mix Ratio for Different Grades of Concrete:

A table is provided with the recommended nominal concrete mix ratios for different grades, including M5, M7.5, M10, M15, and M20. These ratios indicate the proportions of cement, sand, and aggregate necessary to attain the desired compressive strength of the concrete.

Concrete Grade	Nominal Mix Ratio (Cement : Sand : Aggregate)	Compressive Strength
M5	1:5:10	5 N/mm²
M7.5	1:4:8	7.5 N/mm²
M10	1:3:6	10 N/mm²
M15	1:2:4	15 N/mm²
M20	1:1.5:3	20 N/mm²

Nominal concrete mix ratios

It’s important to note that engineers may occasionally make slight adjustments to these ratios based on specific project requirements. For instance, they might increase the sand content to improve workability or reduce the cement content to control costs. However, significant modifications beyond the prescribed proportions can impact the strength and overall quality of the concrete.

Calculation Methods:

Two straightforward methods are employed by civil engineers to determine the quantities of cement, sand, and aggregate for concrete production.

Method 1 involves using the recommended nominal concrete mix ratio to calculate the volume of each component.
Method 2 utilizes the total aggregate value specified in the IS codebook to determine the weight of sand and coarse aggregate needed per 50 kg bag of cement.

Calculation of Cement, Sand, and Aggregate from Nominal Mix Ratio:

During the mixing process of cement, sand, and aggregate, it is important to consider the initial space occupied by cement and sand in between the coarse aggregate particles before they settle into their own spaces. This phenomenon leads to a requirement of more than 1 cubic meter of dry ingredients to produce 1 cubic meter of concrete.

Through standard practices among engineers and the trial-and-error method, it has been determined that the “Total dry volume” of cement, sand, and aggregate needed to create 1 cubic meter of M20, M15, and M10 grade concrete is 1.57 cubic meters. Similarly, the “Total dry volume” of ingredients for 1 cubic meter of M7.5 and M5 grade concrete is 1.52 cubic meters.

It is worth noting that various websites may provide different values for the “Total dry volume” in their calculations. The values mentioned above have been personally verified multiple times and align with the analysis rates provided by government sources.

Calculating Cement, Sand and Coarse aggregate for M20 Grade concrete:

Here is the step-by-step calculations for determining the volume and weight of cement, sand, and aggregate required for 1 cubic meter of M20 grade concrete from Nominal Mix Ratio.

The prescribed Nominal Concrete Mix Ratio of M20 grade concrete is 1:1.5:3.

Cement = 1 Part
Sand = 1.5 Part
Aggregate = 3 Part
Total dry volume of ingredients required = 1.57 cu.m

Volume of cement needed	= Ratio of cement x 1.57/(1+1.5+3)
	= 1 x 1.57/5 .5
	= 0.285 cu.m
Volume of sand needed	= Ratio of Sand x 1.57/(1+1.5+3)
	= 1.5 x 1.57/5 .5
	= 0.427 cu.m
Volume of aggregate needed	= Ratio of agg x 1.57/( 1+1.5+3)
	= 0.427 x 32
	= 0.854 cu.m

Weight of Cement required for 1 cubic meter of M20 Grade concrete:

Cement is commonly available in kilograms, tons, or bags. To determine the weight of cement required, the volume of cement is multiplied by the bulk density of the specific type of cement being used. For widely used cement types such as PPC and OPC, the standard bulk density is 1440 kg/cu.m.

To calculate the number of bags needed, the resulting weight is divided by the weight of one bag of cement, which is typically 50 kg.

Weight of cement needed	= volume of cement x bulk density of cement
	= 0.285 cu.m x 1440 kg/cu.m
Weight of cement needed	= 410 kg
No of cement bags required	= 410/50
	= 8.2 bags

Alternative method: – 1 cu.m of cement is approximately 28.8 bags.

Weight of cement needed	= volume of cement x 28.8
	= 8.2 bags

Volume of Sand and Aggregate required for 1 cubic meter of M20 grade concrete:

Suppliers commonly provide sand and coarse aggregate in cubic feet or units. Hence converting the required volume of these materials from cubic meters into cubic feet for practical purposes. This allows for easier procurement and measurement of the quantities needed for M20 grade concrete.

To convert the volume from cubic meters to cubic feet, the following conversion factors can be used:

1 cubic meter = 35.32 cubic feet
1 unit = 100 cubic feet

Volume of sand needed	= Volume of sand (cu.m) x 35.32
	=0.427 x 35.32
	= 15.08 cft
Volume of aggregate needed	= Volume of aggregate (cu.m) x 35.32
	= 30.16 cft

Hence 15.08 cft of sand and 30.16 cft of aggregate are required to prepare one cubic meter of M20 grade concrete.

Volume of Cement, Sand and Aggregate required for different Concrete Grades in cubic meter:

GRADE	CEMENT	SAND	AGG
M20	0.285 m³	0.427 m³	0.854 m³
M15	0.224 m³	0.448	0.896 m³
M10	0.157 m³	0.471 m³	0.942 m³
M7.5*	0.117 m³	0.471 m³	0.942 m³
M5*	0.094 m³	0.471 m³	0.942 m³

Volume of cement sand and aggregate needed for different concrete grades in cubic meter

Volume of Cement, Sand and Aggregate required for different Concrete Grades in kilogram and in cubic feet CFT:

GRADE	CEMENT	SAND	AGG
M20	410 kg	15.01cft	30.16 cft
M15	322kg	15.82cft	31.65cft
M10	226kg	16.64cft	33.27cft
M7.5*	169kg	16.64cft	33.27cft
M5*	135 kg	16.64cft	33.27cft

Weight of cement and cubic feet of sand and aggregate needed for different concrete grades

As mentioned earlier, 1.52 cubic meters of dry aggregate (cement + sand + aggregate) is required to produce 1 cubic meter of M7.5 and M5 concrete.

Number of Cement bags and Volume of Sand and Aggregate required for different Concrete Grades:

GRADE	CEMENT	SAND	AGG
M20	8.2 bags	15.01cft	30.16cft
M15	6.4 bags	15.82cft	31.65cft
M10	4.5 bags	16.64cft	33.27cft
M7.5*	3.38 bags	16.64cft	33.27cft
M5*	2.7 bags	16.64cft	33.27cft

Weight of Sand and Aggregate Required per 50kg Bag of Cement:

The IS456 code book provides the value of the total dry aggregate required per 50 kg bag of cement for different grades of concrete. This value represents the combined weight of both sand and coarse aggregate needed to achieve the desired concrete mixture.

CONCRETE GRADE	TOTAL AGGREGATE ( FINE + COARSE )
M 5	800 kg
M 7.5	625 kg
M 10	480 kg
M 15	330 kg
M 20	250 kg

Weight of Sand and Aggregate needed for M20 Grade Concrete per 50kg bag of cement:

According to the IS456 table, to prepare M20 grade concrete, you will need 250 kg of total dry aggregate (a combination of sand and aggregate) for each 50 kg bag of cement. The recommended ratio of fine aggregate to coarse aggregate is 1:2, which can be used to determine the individual weights of sand and coarse aggregate.

F.A : C.A = 1 : 2

Sand (fine aggregate) = 1 part

Coarse aggregate = 2 Part

Total aggregate required = 250 kg

Sand needed per bag of cement	= Ratio of sand x 250 /(1+2)
	= 1 x 250 /(1+2)
	= 83 kg ~ 85 kg
Aggregate needed per bag of cement	= Ratio of agg x 250 /(1+2)
	= 170 kg

Weight of Sand and Aggregate required per 50kg bag of cement for different Concrete Grades:

GRADE	CEMENT	SAND	AGG
M20	1 bag	85 kg	170 kg
M15	1 bag	110 kg	220 kg
M10	1 bag	160 kg	320 kg
M7.5	1 bag	210 kg	415 kg
M5	1 bag	265 kg	535 kg

Water Content Requirement for different Concrete Grades as per IS456 Codebook:

The water content guidelines provided by IS456 Codebook specify the recommended amount of water per 50 kg bag of cement for various concrete grades. Adhering to these guidelines is crucial for achieving proper hydration of the concrete mixture and ensuring its overall quality.

CONCRETE GRADE	WATER PER 50KG BAG OF CEMENT
M5	60 Liters
M7.5	45 Liters
M10	34 Liters
M15	32 Liters
M20	30 Liters

Water required per 50kg bag of cement for different concrete grades.

Conclusion:

By following the methods outlined in this comprehensive guide, you can accurately calculate concrete mix ratios for different grades. Whether you’re involved in on-site construction or large-scale production, understanding these calculations is crucial for achieving high-quality concrete that meets the desired specifications and strength requirements.

Trust the verified information and industry standards presented in this article to make informed decisions and produce durable and reliable concrete for your projects.

  Weight to volume ratio of SAND AND AGGREGATE are different in different grades i.e. M20 M15 etc. How has this difference crept in and confuse us? Quantities of components should not differ whether we follow weight method or volume method.
  M20 85 kg=15 cft
  M15 110 kg=15.82 cft
  M10 160 kg=16.64 cft
  M5 265 kg=16.64 cft
  (All sand quantities) this is to be corrected to avoid propogation of wrong information. Corrected quantities may be mailed to me or correct explanation may be mailed to me.

  I understand your question. You should understand that Nominal Mix concrete and Design mix concrete are both different. Though they both have the same Grade name, nominal mix concrete is usually designed for higher strength then mix design concrete. This is due to the fact that while designing nominal mix concrete we don’t consider various factors like the type of sand and “compactness” of sand and, presence of moisture absorbtion. To put it simply that while designing nominal mix concrete, we design for bulk densities of the materials which vary based on the compaction of the material. So, 1. weight to volume ratio WILL differ as any nominal ratio prescribed are only approximation as stated in code books for the reason mentioned above. 2. Quantities of the material will differ but only in acceptable range. 3. The quantities given above are in par with Rate of Analysis of various states and the quantities in the weight given is directly from IS456 recommendation for Nominal mix concrete. If you want accurate proportion and know what you are doing then calculate bulk density of sand and aggregate supplied to your site and tweek the weight proportion ratio to get the volume proportion. The cushion should be provided because the volume is not absolute like weight it differs based on compaction, grading and moisture content of the aggregate.

Good morning sir, It is very useful information. Now I have started G+2 building construction in 2000SFT (Ground floor area). I have given the contract for construction. They are using 1 : 2.5 : 3 (Actually they have suggested 1 : 2.5 : 3.5 ) for concrete and 1 : 6 for brick work. We are using Ultratech 53 grade cement (OPC) cement. May I know is it good?

Reply
1. Prakash Kumar Sekar
  
  Contractors usually add extra sand to reduce the cement content and also to increase the workability(consistency) of concrete. 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. Too much sand causes shrinkage and this will not give high-density concrete. Hence use 1:2:3 for good strength and 1:2.5:3.5 for moderate strength.
  
  If you want to increase strength then reduce the water content and use Chemical admixtures like super plasticisers. If you want good compaction and high density then you can use two different types of aggregates like 10mm aggregate and 20mm aggregate.

  Calculate the concrete quantity required in cubic meter and then multiply the quantity with the cement sand and aggregate for 1 cubic meter of concrete.
  
  In your case
  Volume of concrete = 1.7 x 1.7 x 0.5 = 1.4 cu.m
  It looks like you are using m20 grade mix with extra sand. If you follow that mix proportion then to calculate use this following method.
  Total ratio = 1 + 2 + 3 = 6
  Cement required = (1/6) x 1.5 = 0.25 cu.m (refer the post to change cu.m to bags)
  Sand = 0.25 x 2 = 0.5 cu.m
  Aggregate = 0.25 x 3 = 0.75 cu.m
