This article covers the mix design calculation of M35 Grade Concrete with Ground Granulated Blast Furnace Slag (GGBS) admixture and Poly Carboxylite type super plasticiser as per Indian Standard Codebook IS10262(2009) – Guidelines for Concrete Mix Proportioning. Here, M denotes Mix and Number denotes characteristics compressive strength of concrete of 150 mm cube after 28 days. Of Cement) + Water Content +Ca / Sp. For example, for M20 grade of concrete mix, its compressive strength after 28 days should be 20 N/mm 2. Specific Gravity Pc = Coarse Aggregate Content as percentage of total Aggregates. From combined gradation of Coarse aggregates it has been found out that the proportion of 53:47 of 20 mm & 10 mm aggregates produces the best gradation as per IS: 383. Concrete mix ratio table Ishan Kaushal for this valuable information. A simple table showing concrete mix ratios (Design mix & Nominal mix) for various concrete grades, a typical calculated example of M40 grade concrete and required water proportion for most ratios.

(adsbygoogle = window.adsbygoogle || []).push({}); The Minimum grade of concrete for Plain Cement Concrete (PCC) is M15, The Minimum grade of concrete for Reinforced Cement Concrete (RCC) is M20, As per IS 456:2000, the grades less than M20 should not be used in RCC works. If we mention M10 concrete, it means that the concrete has 10 N/mm2 characteristic compressive strength at 28 days. Of Cement) + Water Content +(Fa / Sp. There are two types of concrete plain cement concrete (PCC) and reinforcement cement concrete (RCC). 2, meet the concrete peaceability. Standard Grade of Concrete : M25 : 1 : 1 : 2 : 25 MPa : 3625 psi : M30 : Design Mix : 30 MPa : 4350 psi : M35 : Design Mix : 35 MPa : 5075 psi : M40 : Design Mix : 40 MPa : 5800 psi : M45 : Design Mix : 45 MPa : 6525 psi : High Strength … Fine Aggregate : 2.62, Take Sand content as percentage of total aggregates = 36%, Select Water Cement Ratio = 0.43 for concrete grade M35, (From IS: 10262 for 20 mm nominal size of aggregates Maximum Water Content = 186 Kg/ M3 ), Hence, Cement Content= 172 / 0.43 = 400 Kg / M3. Reinforced Concrete (RC) RC is used for a series of designated concretes that are used in concrete that will be reinforced, pre-stressed or containing embedded steel. But as per MORT&H Table 1700.5 required target mean compressive strength = 35 + 12 = 47.00 N/mm² where 12 is the current margin. Normally, we used the water-cement ratio falls under 0.4 to 0.6 per IS Code 10262(2009) for nominal mix i.e. 10262- 1982) Select Water Content = 172 Kg (From IS: 10262 for 20 mm nominal size of aggregates Maximum Water Content = 186 Kg/ M 3) Hence, Cement Content= 172 / 0.43 = 400 Kg / M 3. * Pf )}, 1000(1-a0) = {(Cement Content / Sp. In this post, we are going to explain that in detail. Hope you learned something useful. If we mention M10 concrete, it means that the concrete has 10 N/mm2 characteristic compressive strength at 28 days. Can adopt this value while doing the concrete mix design those who are working other than highway project. Media | we already discussed the mix design here. 3, meet the durability of the use of concrete. Designed Concrete Mix/Ratio. How to understand the correction factor in mix design to easy way, Why Standard deviation is considered as 1.91 where as it should be assumed as 5 for M35, About Us | The basic requirements for the design of concrete mix ratio are: 1, meet the strength grade of concrete design. We could say the grade of concrete is the only thing we do care lot while concreting. Gr. We use different grades of concrete for different parts of the building.
