M10 concrete mix design -Steps|IS-10262:2009 |IS-456:2000

In this emerging world of modern design of structures, Concrete acts as the backbone of civil engineering. A structural engineer's first and foremost objective is to build an efficient and durable concrete structure that is also aesthetically pleasing. Here comes the role of a concrete designer. When the aim is to build a concrete structure that is efficient and durable, this demands to follow the concrete mix design steps as per IS codes (IS- 10262:2009 and IS- 456:2000).

In short, the mix design determines the final quality of the concrete, and it is essential to follow mix design procedures and standards (IS- 10262 : 2009 and IS- 456 : 2000) to ensure that the mix meets the desired strength and performs as intended.

What are the different design stipulations for the concrete mix design ?

This post will help you to have a brief idea of the different parameters required and will also make you aware about the different exp. data required for conducting the mix design of concrete.

The different design stipulations required for the desired mix are shown in the table below:

Stipulations for proportioning
Type of Concrete	PCC
Grade Designation	M10
Shape of Particle	Angular
Slump	80 mm
Water- Cement Ratio	0.35
Exposure Condition	Mild
Concrete Placement	By Hand
Degree of Supervision	Fair

The different experiemental data required for the desiered mix are shown in the table below:

Sieve analysis
Fine Aggregate	Zone 4
Coarse Aggregate	20 mm

Chemical Admixture
Volume ( By mass of cement)	2%
Water Content Reduction	Zero

Test data for materials
Standard Deviation	4.50 MPa

Specific Gravity of Coarse Aggregate	2.74
Specific Gravity of Cement	3.15
Specific Gravity of Admixture	1.145

Step by step detailed procedure for concrete mix design of M10 grade as per IS - 10262:2009 and IS- 456:2000

The detailed step by step procedure for mix design of M30 grade, according to IS - 10262:2009 and IS- 456:2000 is given below:

• Mean compressive strength: Calculate the target mean compressive strength at 28 days

target mean compressive strength	characteristic strength + 1.65 X Standard Deviation
target mean compressive strength	10 + 1.65 X 4.50 = 17.42 \frac{N}{mm2}

Where sufficient test results for a particular grade of concrete are not available, the value of standard deviation could be taken from Table 1 of IS-10262.

• Water cement ratio: In this step we select maximum w/c ratio, which should be as per Table 5 of IS - 456: 2000.

Maximum water-cement ratio	0.60
​ Adopted water-cement ratio	0.35

• Entrapped air: For the maximum size of aggregate used the air content is estimated.

• Water content and fine to total aggregate ratio: The selection of water content is based on Table 2 of IS:10262:2009. Maximum water content for 20 mm aggregate and a slump value of 25 to 50 mm = 186.0 l. But in our problem the value of slump is 80 mm, so we need to alter the water content.

Estimated water content	186 + 3.\frac{6}{100} X 186 = 192.70 litres

• Cement content: The cement content per unit volume of concrete is computed sing Table 5 of IS:456:2000:

Minimum cement content for mild expossure condition	220 kg/m3
cement content	192.\frac{70}{0}.54 = 356.85 kg/m3

• Aggregate content: Volume of coarse aggregate per unit volume of total aggregate for corresponding to 20 mm maximum size and zone IV of fine aggregate = 0.66 - Table 3 of IS- 10262:2009.

Correction on the volume of different ingredients

Based on the water-cement ratio	0.03
Based on placement	0.00

Hence Volume of

Coarse aggregate	0.69
Fine aggregate	0.31

$$V = \left( W + \frac{C}{S_c} + \frac{f_a}{P \, S_{fa}} \right) \times 10^{-3}$$ $$C_{a}=1- \frac{P}{P} \times f_{a} \times S_{ca}/ S_{fa}$$

Mass of Coarse aggregate	1195.85 kg/m3
Mass of Fine aggregate	537.27 kg/m3​

In order to check the efficiency of the designed mix, we shall prepare different trial mixes and the same are tested to check the strength and workability of the designed mix. If the designed mix fails to meet the desired properties, then a minor adjustment is done in the water-cement ratio and aggregate quantities; then again, the trial mixes are prepared.

Conclusions:

The nominal mix for M10 grade is (1:3:6). The quality of concrete depends on a number of factors and the standard mix just gives us a rough estimate of the quantities of material required, this is exactly where a design mix procedure is required as it is evident from the results that for the same mix proportion when exposure and material properties are changed mix proportion also changes. Therefore, standard mixes may be used only for very small jobs.

In this post, you learned the following key points:

• Concrete mix design: The proportions of the various ingredients in the mix determine the final properties and performance of the concrete.

• Indian standard code: Follow IS - 10262:2009 and IS- 456:2000 to do the concrete mix design efficiently.

• Concrete mix design application: You can do the concrete mix design in just one click using the concrete mix design application.

Hope this post helped you to learn the step-by-step procedure for concrete mix design using IS code ( IS - 10262: 2009 and IS - 456: 2000)
