Ans. : bags ( kgs) of cement, cu ft sand and 31 cu ft aggregate quantity are used in m15 grade of 1m3 concrete. 4) water cement ratio :weight of water to weight of cement is water cement ratio .water cement ratio for m15 grade of concrete is about Volume of cement = m3. 1m3 = 1000 litre
Concrete mix ratios are prescribed ratio of cement, sand and aggregate to get the desired strength of concrete. The volumetric mix ratio of M20 concrete is 1::3, hence 1 part of cement, part of sand and 3 part of aggregate in volume will be taken for preparing concrete.
Mix ratio of concrete defines the ratio of cement sand and aggregate by volume in that order. So a mix ratio of 1:2:4 represents Cement: Sand: Aggregate 1:2:4 (by Volume) Material Requirement for Producing 1 Cum of Nominal Mix Concrete
#0183;#32;Normal grade of concrete are based on nominal mix ratio of cement, sand and aggregate have comparatively lower compressive strength than standard grade of concrete. Normal grade of concrete are M25,M20,M15,M10, amp; M5 generally based
The ratio of cement sand and aggregates in concrete depends on the grade of concrete ..if you are making an M2025 grade of concrete you may require around 300315 Kgs of cement around 800 Kgs of Sand and 1300 Kgs of coarse aggregates .. however these are just mere numbers if you follow proper Mix design procedures you can save on cement and other materials also
Calculate cement, sand, coarse aggregate and water to prepare M5,, M10, M15 and M20 ratio grade concrete in volume and weight.
M15 GRADE. The mix ratio is 1:2:4 (1 Cement, 2 Sand and 4 Aggregate) It is used as PCC (Plain Cement Concrete) Application/use: It can be used in the construction of Levelling course, bedding for footing, concrete roads, etc. M20 GRADE. The mix ratio is 1::3 (1 Cement, Sand and 3 Aggregate) It is used as RCC (Reinforced Cement Concrete)

#0183;#32;The Concrete mix ratio for M20 grade of concrete is 1::3 that mean 1 part of cement, part of sand (fine aggregate) and 3 parts of aggregate (crushed stone) in volume and then batched for mixing. To know the Concrete Mix Design follow below:Mix Design (M) = Cement: Sand :Aggregate
M20 = 1: : 3 (C : S : A) M 20 is the grade of concrete which ratio is 1 ratio ratio 3 okay, one is cement and is sand and 3 is aggregate. Assume that we will find the materials

Weight of sand = volume x density, Density of Sand = 1650 kg/m^3 Weight of sand= x 1650= 693 kg ( tonnes) 3 Findout quantity of Coarse
Nominal concrete mix are low grade concrete mixes which are used for small and unimportant works. In this method, fine aggregate quantity is fixed irrespective of cement and coarse aggregate proportions. Hence, the quality of concrete mix will be varied and required strength may not be obtained. In Nominal mix design watercement ratio also not
Concrete grades are denoted by M10, M20, M30 according to their compressive strength. The M denotes Mix design of concrete followed by the compressive strength number in N/mm 2 Mix is the respective ingredient proportions which are Cement: Sand: Aggregate Or Cement: Fine Aggregate: Coarse Aggregate.
m15 concrete ratio in 1 m3: m15 concrete ratio in 1 cubic metre is mixture of cement, sand and aggregate by adding water. cement sand amp; aggregate ratio in m15 grade 1m3 concrete is 1 : 2 :4 in which one part is cement two part is sand and 4 part is aggregate.
Dry aggregate contains 33 to 34% air voids, whereas sand contains 20% air voids and cement contains very fine particles hence it contains negligible are voids so we can ignore it. Now add the air voids of sand and aggregate that are 20% +34% = 54% so this is the reason we
Excess reduction of cement content or increase of sand content will adversely affect the strength of concrete. Hence it is advisable not to increase the fine aggregate (River Sand and M sand) content more than 30% above the prescribed ratio in any case.
