M10 GRADE The mix ratio is 136 1 Cement 3 Sand and 6 Aggregate It is used as PCC Plain Cement Concrete Applicationuse It can be used in the construction of Levelling course bedding for footing concrete roads etc M15 GRADE The mix ratio is 124 1 Cement 2 Sand and 4 Aggregate It is used as PCC Plain Cement Concrete
Concrete mix design as per indian standard code c maximum watercement ratio andor maximum cement content to give designated the concrete mixes into a number of grades as m10
Number of grades as m10 m15 m20 m25 m30 m35 and m40 in this designation the letter m refers to the mix and the number to the specified 28 day cube strength of mix in nmm2 the mixes of grades m10 m15 m20 and cement content cement concrete
Aug 22 2020 the concrete grades converted various mixes into the two proportions like example differentiate with m20 concrete mixing proportions will be the 1153 sand cement coarse aggregates ratio the concrete grade are denoted strength by m5 m10 m20 according compressively
When the ratio is in proportion say 124 136 148 etcthey are always in vol when strength is specified by m10 2025 etc it is a design mix to deliver the required strength of concie 10 nmm etc it is not easy to easy to mix the different ingredients always by wt
May 29 2018 the different grades of concrete are given as m10 m15 m20 m25 m30 m35 and m40 in the classification of concrete mix the letter m denote mix design and the numbers represent the predetermined works cube strength of 15cm cube after curing of 28 days in nmm2 the works cubes strength refers to the strength archived
9102018 m75 grade mix ratio is 148 1 cement 4 sand and 8 aggregate applicationuse to provide the uniform surface to the foundation concrete and to prevent the direct contact of foundation concrete from the soil ordinary grade of concrete m10 grade mix ratio is 136 1 cement 3 sand and 6 aggregate it is used as pcc plain
With constant research and development in the field of cement technology and its manufacturing process a m20 mix of 1153by volume would be too richover engineered and uneconomical 75 bags of cement per cum and will ultimately result into a m30 concrete and above the reason being latest generation of 53 grade opc cement is
Oct 29 2017 notes cement content prescribed in this table is irrespective of the grades of cement the additions such as fly ash or ground granulated blast furnace slag may be taken into account in the concrete composition with respect to the cement conent and watercement ratio if the suitability is established and as long as the maximum amounts taken into account do not exceed the limit of
Calculation of cement contentwater cement ratio 035 water content per cum of concrete 144 kg cement content 144035 4114 kg m 3 say cement content 412 kg m 3 as per contract minimum cement content 400 kg m 3 hence ok 5 calculation for ca amp fa formulas can be seen in earlier postsvolume of concrete 1 m 3
Mar 08 2019 one easier solution to remember concrete ratio we know that m15 ratio is 1 2 4 above the m15 only decrease05 in sand and aggregate 1below m15 we increase sand 1 and aggregate 2 its the easiest form remember the ratio of concrete
For m20 30 liters of water per 50kg cement total amount of water required 30 x 4032 50 24192 litre 8064 bags of cement required for 1 cum of m20 grade concrete 630 kg of sand required for 1 cum of m20 grade concrete 1260 kg of 20mm aggregate is required for 1 cum of m20 grade concrete
M10 and m20 grade of concrete is used in mass concrete work m15 is generally used for all purpose of general nature such as rcc slabs and flooring m20 and m25 is used for thin rcc members such as precast members shed roofs thin shell etc m35 and m40 are used in prestressed concrete structures ie for posttensioned and pretensioned
M 20 is identified as the concrete grade in which m denotes the mix and 20 denotes the compressive strength of concrete cube after 28 days of curing in nmm 2 there are various grades of concrete that can be used like m10 m15 m20 m25 m30 etc
Types of grade materials are mixed in specific proportions to obtain the required strength the strength of the mix is specified as m5 m10 m15 m20 m25 m30 etc where m signifies mix and 5 10 15 etc as their strength in knm 2in the united states concrete strength is
The mixes of grades m10 m15 m20 and m25 conform roughly to the mix proportions 136 124 1153 and 112 correspondingly design mixes in these types of mixes a designer indicates the performance of the concrete but the ratios of mixes are defined by the producer of concrete irrespective of the minimum cement content is set
Calculate cement sand amp aggregate m20 m15 m10 m5 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 1153 hence 1 part of cement 15 part of sand and 3 part of aggregate in volume is needed to prepare m20 grade concrete
As with portland cement concrete the cement content necessary to achieve a workable concrete increases with decreasing watercement ratio figure 1324 shows the relationship of slump to watercement ratio for various cement contents in order to achieve a workable concrete at wc 04 a minimum cement content of 400 kgm 3 is necessary to ensure goodquality wellcompacted concrete
4 meet the above conditions to save cement and reduce the cost of concrete the strength of concrete is divided into twelve grades such as c75 c10 c15 c20 c25 c30 c35 c40 c45 c50 c55 c60 and so on the concrete mix ratio refers to the proportion of the components in concrete cement water sand and stone
How to calculate of cement sand and aggregate for m10 quantity of sand quantity of cement x 15 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 standard concrete m25 112
Advantages of concrete mix design the advantages of concrete mix design are as follows 1 desired proportions of each ingredient the main aim of the concrete mix design is to find out the desired proportion of each ingredients which are cement coarse aggregate fine aggregate water etc to obtain the required properties of resulting mix
