The Concrete mixing ratio for M35 grade concrete as per IS Mix design is1:1.6:2.907 (cement:Fineaggregate:Coarse aggregate)The ratio obtained is as per design calculations by considering the grade of aggregates and the type of cement used.The Water/cement ration is 0.43
weight of 1 cubic mitre of concrete
Normally it's a one-two-three mix. One part cement, 2 parts sand, 3 parts aggregate. The sand is graded which means it has a variety of grain sizes.
It can be used, provided you know the maximum weight on vehicles on it. From experience, 30 ton trailers can run comfortably on a 200mm thick g-25 concrete mix..
a nominal mix is that mix in which we adopt the various ingredients such as1:2:3,1:2.5:4etc here the strength will not be the desired strength and generally here we take the ingredients per unit vol a design mix is that mix in we find the ratio of the different ingredients as per the desired strength and the ingredients would be in per unit weight

40 20 concrete design mix is the water to cementitious materials ratio. This is what determines the class of the design mix.
The mix proportion for M40 concrete is 1:1.65:2.92W/C ratio = 0.4The design calculation is as per IS mix design
Its the process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design.
a concrete mix of suitable slump as per mix design should be selected
Ans: M15 grade indicates the grade of concrete used in the structure i.e M indicates the design mix proporation and 15 indicates the compressive strength of conctrete at 28 days in N/mm2

it has more cement than the normal mix
