The scope of this
standard was very
limited without giving
due considerations to
many factors & recent
developments
affecting the concrete
mix proportioning.
The scope of the standard has been enlarged to include different types & grade of concrete giving due
considerations to various other important factors
The standard has been divided to 5 major sections to include: General terms & conditions in a detailed
manner, Design of ordinary & standard grades of concrete, HSC (M65 – M100), SCC & Mass concrete
Initial data to be provided for mix proportioning has been made more encompassing by including the
provisions of IS:383-2016, usage of admixtures
Formula for Target Mean Strength has been refined to include new factor based on grade of concrete
so as to ensure minimum margin between Characteristic strength & target mean strength.
Calculations of Standard deviation has been detailed
A graph of w/c ratio verses 28-D compressive strength of concrete has been introduced for OPC, PPC &
PSC for assuming initial w/c ratio.
The standard was
applicable only for
ordinary & standard
grades of concrete up
to M55.
Illustrative examples for mix proportioning of concrete using PPC, OPC+fly ash, OPC+ GGBS, HSC, SCC &
mass concrete has been included.
Guidelines for usage of water reducing admixture has been introduced as an informatory annex
Consideration of Air Content has been re-introduced in the design of normal (non-air entrained)
concrete mix.
Overview of Major Modifications in IS:10262 - 2019
• First published - 1982
• 1ST Revision – 2009
• 2ND Revision - 2019
The standard has been divided into five sections as given below:
• General
• Ordinary and Standard grades of concrete
• High strength grades of concrete
• Self Compacting Concrete
• Mass Concrete
MAJOR MODIFICATIONS MADE IN REVISED 2019 VERSION
Relation between free water-cement ratio and 28 days Compressive strength of Concrete
A graph with 3 curve depicting the relationship between 28-days compressive strength of concrete &
w/c ratio has been introduced for working out free w/c.
• Curve 1 – For expected cement 28-D strength of 33 and < 43 MPa,
• Curve 2 - For expected cement 28-D strength of 43 and < 53 MPa
• Curve 3 - For expected cement 28-D strength > 53 MPa
• In absence of actual cement strength Curve 1, 2 & 3 may be used for OPC33, OPC43 &
OPC53 grade cements respectively
• While using PPC/PSC, if actual cement strength is available then any curve can be used based
on the actual strength
• In absence of actual cement strength of PPC/PSC, use Curve 2.
.
MAJOR MODIFICATIONS MADE IN REVISED 2019 VERSION Contd…
• Reduce by 10 kg for sub-angular aggregates,
• Reduce by 15 kg for gravel with some crushed particles (Earlier it was 20 kg)
• Reduce by 20 kg for rounded gravel (Earlier it was 25 kg) to produce same
workability.
The adjustments to be made in the water content (For 50mm slump) given in Table-4 for
different shapes of aggregates has been revised as follows;
MAJOR MODIFICATIONS MADE IN REVISED 2019 VERSION Contd…
HIGH STRENGTH CONCRETE (GRADE M 65 AND ABOVE)
 Procedure to attain HSC is similar to that of ordinary/standard strength concrete.
 Quality of aggregates for HSC.
o coarse aggregate shall be strong, sufficiently sound, free of fissures or weak planes,
clean and free of surface coating and shall meet the requirement of IS:383
Parameter Requirement
Impact/crushing value < 22 percent

HIGH STRENGTH CONCRETE (GRADE M 65 AND ABOVE)
Air Content – Standard Concrete Air Content – High Strength Concrete
Selection of Water Content without Chemical Admixture–
HIGH STRENGTH CONCRETE (GRADE M 65 AND ABOVE)
Selection of W/C Ratio
• The clause has been made more elaborate to take into consideration the
usage of multiple SCM/MA like FA, GGBS, SF & others for part cement
replacement. It has allowed for increase in cementitious material content
under such conditions, based on experience or by 10% for preliminary trial
• The limits of addition of FA & GGBS are kept open based on the project
requirement and the quality of these materials.
HSC - Calculation of Cement/Cementitious Materials Content
HSC - Recommended Dosage of 04 Mineral Admixtures Materials (FA, GGBS, SF & MK)
HSC - coarse aggregate volume per unit volume of total aggregate
Reduce the estimated CA content by 5% for pumpable concrete &
concrete used in congested reinforcements.
SELF COMPACTING CONCRETE
It has been divided into different classes based on slump flow. Segregation resistance &
viscosity for different areas of application
Typical Range of Mix Constituents –
• Fines content (Particles < 125 micron) – 400-600 kg/m3
• Fine Aggregate Content – 48-60 % by mass of total aggregates
• Water Content – 150 – 210 kg/m3

STEP 4 SELECTION OF WATER-CEMENT RATIO
• Select the water-cement ratio from the relationship established between strength and
free water-cement ratio for the materials actually used OR select preliminary free
water-cement ratio corresponding to 28 day target strength OR;
• Preliminarily, find out the Maximum water-cement ratio from Table 2 (Table 5 of IS
456:2000) based on the environment exposure condition.
• The above water-cement ratio should be checked against the limiting water-cement
ratio for the durability requirements.
• Adopt lower of the two values.

• Saturated surface dry aggregates
• Angular coarse aggregate and
• Slump of 50mm
The above data holds good for:
STEP 5 SELECTION OF WATER CONTENT
CORRECTIONS TO BE APPLIED ON WATER CONTENT –
I) Based on aggregates : Reduction in water content
Type of aggregate Reduction of water content(%)
i) Sub-angular 10 kg
ii) Gravel with crushed particles 15 kg
iii) Rounded gravel 20 kg
II) Based on slump : Increase in water content
For slump other than 50mm,
Increase/Decrease the water content by 3% for every 25mm Increase/Decrease in slump.
III) Use of Admixtures : Reduction in water content
Water reducing admixtures – 5 to 10%
Super plasticizers – 20-30%
STEP 6 CALCULATION OF CEMENT CONTENT
• Calculate the cement content per unit vol. of concrete from the water-cement ratio
obtained in Step 4.
• Check cement content against the min. cement content for the requirements of
durability under various conditions of exposure (Ref – Table 5 of IS 456 : 2000)
• Adopt Greater of the two values.
• Maximum Cement content shall be in accordance with IS 456 Clause 8.2.4.2.
STEP 7 ESTIMATION OF COARSE & FINE AGGREGATE PROPORTION
STEP 7 ESTIMATION OF COARSE & FINE AGGREGATE PROPORTION
STEP 7 ESTIMATION OF COARSE AGGREGATE PROPORTION
CORRECTIONS TO BE APPLIED –
• For water ratio other than 0.50,
- For every 0.05 increase in w/c, decrease the proportion of vol. of CA by 0.01;
- For every 0.05 decrease in w/c, increase the proportion of vol. of CA by 0.01.
• For pumpable concrete, reduce the volume of coarse aggregates by 10%
COMBINATION OF DIFFERENT COARSE AGGREGATES FRACTIONS
Coarse aggregates of different sizes may be combined in suitable proportions so as
to result in an overall grading conforming to Table2 of IS383 for particular nominal
MSA
ESTIMATION OF FINE AGGREGATE PROPORTION
Vol. of Fine aggregates = 1 – Vol. of Coarse aggregate
STEP 8 MIX CALCULATIONS
Vol. of the Cementitious material, water and admixture are obtained by
Volume of all in aggregates = Vol. of Concrete – (Vol. of Cement
+Vol. of water + Vol. of admixture)
(if used)
Mass of coarse aggregate = Vol. of all in aggregate X the Vol. of
CA X Sp. gravity of CA X 1000
Mass of Fine aggregate = Vol. of all in aggregate X the Vol. of
FA X Sp. gravity of FA X 1000
Mass of resp. materials X 1
Specific gravity of resp. materials 1000
The proportion of all the ingredients should be presented.
Cement –
Fly ash -
Water –
Fine aggregates –
Coarse aggregates –
Chemical admixtures –
Note – All the aggregates considered are in saturated surface dry condition. If aggregates in any other condition are
used, following allowances should be made.
• Allowance for free (surface) moisture contributed by the CA and FA should be considered while calculating the
requirement for the mixing water.
• If aggregates are dry, the amount of mixing water should be increased by an amount equal to the moisture likely to
be absorbed by the aggregates.
• Adjustments are also required to be made in the mass of aggregates.
STEP 9 MIX PROPORTIONING
• Slump of Trial Mix No.1 shall be measured, it shall be observed for segregation,
bleeding and finishing properties.
• If the measured slump of Trail Mix No. 1 is different from the stipulated value, the
water and/or admixture content shall be adjusted suitably.
• The mix proportion considering the above adjustment shall be recalculated keeping
the free water-cement ratio at the pre-selected value. This shall be Trial Mix No.2.
• Two more Trial Mixes No.3 and No.4 shall be made by varying the free water-
cement ratio by ± 10% of the preselected value.

Example 1 : MIX PROPORTIONING FOR CONCRETE OF GRADE M30
From Table 1, standard deviation s = 5 N/mm²
Target Mean Strength (f’ck) = fck + (1.65 s)
= 30 + (1.65 X 5) =38.25 N/mm2
B1. Target Mean Strength
OR
Target Mean Strength( F’ck) = Fck + X
=30+6.5 = 36.5 N/mm2
B2. Selection Of Water-cement Ratio
From Table 2, maximum w/c = 0.50, Based on Graph or experience adopt 0.45.
0.45< 0.50. Hence Ok.
Example 1 : MIX PROPORTIONING FOR CONCRETE OF GRADE M30
From Table 4, water content = 186 litre
(for 20mm aggregate 50mm slump)
For 100mm slump , correction needs to be applied, i.e. increase water content by 6%
Water content for 100mm slump = 186 + (6/100) X 186
= 197.2 litre
As superplasticizer is used, the water content can be reduced by 20% and above.
Based on trials, water content reduction of 15% has been achieved. Hence, water content
= 197.2 X 0.85
= 167.6 litres
B3. Selection of water content
Example 1 : MIX PROPORTIONING FOR CONCRETE OF GRADE M30
B4. Calculation of cement content
From step 4, adopted w/c = 0.45
From step 5, water content = 167.6 litres
 Cement = 167.6/0.45 = 372.4 kg/m³
Check
From Table 2, for ‘Moderate’ exposure condition, Minimum cement
content = 300kg/m³
372.4 kg/m³ > 300kg/m³, Hence OK.
Example 1 : MIX PROPORTIONING FOR CONCRETE OF GRADE M30
Calculation of Fly ash content
Fly ash content of total Cementitious material = 30%
Qty of Fly ash content of total Cementitious material = 373 x 30% = 112 kg/m³
Cement OPC = 373 – 112 = 261 kg/m³
Cement (OPC) = 261kg/m³
Fly ash = 112 kg/m³
Example 1 : MIX PROPORTIONING FOR CONCRETE OF GRADE M30
B5. Vol. of CA and FA Content
From Table-4, volume of coarse aggregate corresponding to 20 mm size aggregates & fine
aggregate (Zone II) for w/c 0.50 = 0.62
As the water cement ratio is lower by 0.05, the proportion of volume of coarse aggregates
is increased by 0.01
Volume of coarse aggregates = 0.62 + 0.01
Therefore,
Volume of Coarse Aggregates = 0.63
Volume of Fine Aggregates = 1 – 0.63 = 0.37
Example 1 : MIX PROPORTIONING FOR CONCRETE OF GRADE M30
B6. Estimation of FA Proportion
i) Volume of Concrete = 1m³
ii) Volume of Entrapped Air in Wet Concrete = 0.01 m3
iii) Volume of Cement = (261/3.15) x (1/1000) = 0.082m³
iv) Volume of Fly ash = (112/2.2) x (1/1000) = 0.0509 m3
v) Volume of water = (167.6/1) X (1/1000) = 0.168m³
vi) Volume of Chemical admixture = (3.72/1.1) X (1/1000) = 0.0033m3
Volume of all in aggregates = [1 – 0.01 - (0.082 +0.0509 + 0.168 + 0.0032)] = 0.686 m³
Vol. of the Cementitious material and water are obtained by
Mass of resp. materials X 1
Specific gravity of resp. materials 1000
Example 1 : MIX PROPORTIONING FOR CONCRETE OF GRADE M30
B6. Estimation of FA Proportion contd….
v) Mass of Coarse aggregates = 0.686 X 0.63 X 2.68 X 1000
= 1158.0 kg.
vi) Mass of Fine aggregates = 0.686 X 0.37 X 2.66 X 1000
= 675.0 kg.
B7. Mix Proportion (for 1m³)
Cement = 261.0kg
Fly ash = 112.0 kg
Water = 167.0kg
Fine aggregates = 675.0 kg
Coarse aggregates = 1158.0 kg
Chemical Admixture
( 1% of Total mass of cementations ) = 3.72kg
w/c = 0.45
Example 1 : MIX PROPORTIONING FOR CONCRETE OF GRADE M30
B7. Mix Proportion (for 1m³) contd….
Corrections applied for water content and mass of aggregates considering the Water absorption & Free
moisture:
Water absorption of CA is 0.5%, Free Moisture in FA is 2%.
I) Extra Quantity of water to be added for absorption in case of CA at 0.5%
= (0.5/100) X 1158.0 = 5.8 kg.
II) Extra Quantity of water to be added for absorption in case of FA at 1.0%
= (1/100) X 675.0 = 6.75 kg
III) Quantity of water to be deducted for free moisture in FA at 2%
= (2/100) X 675.0 = 13.50 kg.
Actual water required = 167.0 + 5.8 + 6.75 – 13.50 = 166.0 kg
Actual sand required = 675 – 6.75+ 13.50 = 682 kg.
Actual CA required = 1158.0 – 5.8 = 1152.0kg.

B8. Actual Quantities for Trial No. 1
Cement 265 kg/m³
Fly ash 110 kg/m³

  • 2. REFERRED STANDARDS IS Codes Title 269:2015 Specification for Ordinary Portland cement( 6th Revision) 383 : 2016 Specification for coarse and fine aggregates from natural sources for concrete (3rd Revision) 456 : 2000 Code of practice for ‘Plain and reinforced concrete’ (4th Revision). 1199- 2018 Fresh concrete – Methods of sampling, testing & analysis (Part -6) 2386 : 1963 (Pt 3) Methods of test for aggregates for concrete: Part 3 Specific gravity, density, voids, absorption and bulking 1489 : 2015 (Pt 1 & 2) Specification for Portland pozzolana cement : Part 1 For fly ash based and part 2 calcined clay based, cement mortar and concrete (second revision) 3812:2013 (Pt 1) Specification for fly ash in cement, cement mortar and concrete(2th Revision) 9103 : 1999 Specification for admixtures for concrete (1st revision) 15388 - 2003 Specifications for Silica Fumes 16714 – 2018 Ground Granulated Blast Furnace Slag for use in Cement, Mortar & Concrete - Specifications
  • 3. IS:10262 – 2009 IS:10262 – 2019 The scope of this standard was very limited without giving due considerations to many factors & recent developments affecting the concrete mix proportioning. The scope of the standard has been enlarged to include different types & grade of concrete giving due considerations to various other important factors The standard has been divided to 5 major sections to include: General terms & conditions in a detailed manner, Design of ordinary & standard grades of concrete, HSC (M65 – M100), SCC & Mass concrete Initial data to be provided for mix proportioning has been made more encompassing by including the provisions of IS:383-2016, usage of admixtures Formula for Target Mean Strength has been refined to include new factor based on grade of concrete so as to ensure minimum margin between Characteristic strength & target mean strength. Calculations of Standard deviation has been detailed A graph of w/c ratio verses 28-D compressive strength of concrete has been introduced for OPC, PPC & PSC for assuming initial w/c ratio. The standard was applicable only for ordinary & standard grades of concrete up to M55. Illustrative examples for mix proportioning of concrete using PPC, OPC+fly ash, OPC+ GGBS, HSC, SCC & mass concrete has been included. Guidelines for usage of water reducing admixture has been introduced as an informatory annex Consideration of Air Content has been re-introduced in the design of normal (non-air entrained) concrete mix. Overview of Major Modifications in IS:10262 - 2019
  • 4. • First published - 1982 • 1ST Revision – 2009 • 2ND Revision - 2019 The standard has been divided into five sections as given below: • General • Ordinary and Standard grades of concrete • High strength grades of concrete • Self Compacting Concrete • Mass Concrete MAJOR MODIFICATIONS MADE IN REVISED 2019 VERSION
  • 5. Relation between free water-cement ratio and 28 days Compressive strength of Concrete
  • 6. A graph with 3 curve depicting the relationship between 28-days compressive strength of concrete & w/c ratio has been introduced for working out free w/c. • Curve 1 – For expected cement 28-D strength of 33 and < 43 MPa, • Curve 2 - For expected cement 28-D strength of 43 and < 53 MPa • Curve 3 - For expected cement 28-D strength > 53 MPa • In absence of actual cement strength Curve 1, 2 & 3 may be used for OPC33, OPC43 & OPC53 grade cements respectively • While using PPC/PSC, if actual cement strength is available then any curve can be used based on the actual strength • In absence of actual cement strength of PPC/PSC, use Curve 2. . MAJOR MODIFICATIONS MADE IN REVISED 2019 VERSION Contd…
  • 7. • Reduce by 10 kg for sub-angular aggregates, • Reduce by 15 kg for gravel with some crushed particles (Earlier it was 20 kg) • Reduce by 20 kg for rounded gravel (Earlier it was 25 kg) to produce same workability. The adjustments to be made in the water content (For 50mm slump) given in Table-4 for different shapes of aggregates has been revised as follows; MAJOR MODIFICATIONS MADE IN REVISED 2019 VERSION Contd…
  • 8. HIGH STRENGTH CONCRETE (GRADE M 65 AND ABOVE)  Procedure to attain HSC is similar to that of ordinary/standard strength concrete.  Quality of aggregates for HSC. o coarse aggregate shall be strong, sufficiently sound, free of fissures or weak planes, clean and free of surface coating and shall meet the requirement of IS:383 Parameter Requirement Impact/crushing value < 22 percent Combined Flakiness & Elongation Index < 30 percent Nominal MSA < 20 mm for up to M75 Nominal MSA Preferred 10 & 12.5 mm for M80 & above Fine Aggregate Coarser size is preferred (Zone I or Zone II)
  • 9. HIGH STRENGTH CONCRETE (GRADE M 65 AND ABOVE) Air Content – Standard Concrete Air Content – High Strength Concrete
  • 10. Selection of Water Content without Chemical Admixture–
  • 11. HIGH STRENGTH CONCRETE (GRADE M 65 AND ABOVE) Selection of W/C Ratio
  • 12. • The clause has been made more elaborate to take into consideration the usage of multiple SCM/MA like FA, GGBS, SF & others for part cement replacement. It has allowed for increase in cementitious material content under such conditions, based on experience or by 10% for preliminary trial • The limits of addition of FA & GGBS are kept open based on the project requirement and the quality of these materials. HSC - Calculation of Cement/Cementitious Materials Content
  • 13. HSC - Recommended Dosage of 04 Mineral Admixtures Materials (FA, GGBS, SF & MK)
  • 14. HSC - coarse aggregate volume per unit volume of total aggregate Reduce the estimated CA content by 5% for pumpable concrete & concrete used in congested reinforcements.
  • 15. SELF COMPACTING CONCRETE It has been divided into different classes based on slump flow. Segregation resistance & viscosity for different areas of application Typical Range of Mix Constituents – • Fines content (Particles < 125 micron) – 400-600 kg/m3 • Fine Aggregate Content – 48-60 % by mass of total aggregates • Water Content – 150 – 210 kg/m3
