Answer / harshal.s.khode

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.
Requirements of concrete mix design

The requirements which form the basis of selection and
proportioning of mix ingredients are :

a ) The minimum compressive strength required from
structural consideration

b) The adequate workability necessary for full compaction
with the compacting equipment available.

c) Maximum water-cement ratio and/or maximum cement content
to give adequate durability for the particular site
conditions

d) Maximum cement content to avoid shrinkage cracking due
to temperature cycle in mass concrete.

Answer / a.jagadesh

Mix design is to get a compressive strength of rcc cube to
20n/mm2 or above.

Answer / mohammed essam

as per the design, a load is given and the strength of concrete is being provided to the ready mix company, for ex M800, It implies that the structure requires a concrete capable of taking load upto 800N/mm2, the ready mix company mix ADMIXTURES such as fly ash, rise husk etc. its known as the design mix

mix design is based on weight

Answer / bharani.r

mix the ingredients of concrete like cement, aggregates,
water as per code given for given component like 1:2:4, etc.,

Answer / sanjay kumar chatterjee

Mix design is a design mix that is made to acquire the
required strength as per particular requirement, the ratio
should be such that if 200Kg/cm2 is required than M20 is to
be designed, it is not a simple ratio mix of 1:2;4
or1;1.5:3 it depends on many factors

Answer / gadevinilkumar

what is new version of concrete mix design s.p.36 or not

Answer / sudhakar.a

It is the process to determining the ingredients of
concrete like cement,sand and aggregate in order of
proportion (i.e)1:2:4,1:3:6,1:4:8,1:5:10

Answer / pari

to find the amound of cement ,sand,coarse aggregate for
perticular ratio(like 1:2:4).

Answer / hafeez

as per ratio mixing the concrete it's called mix design .
i think so ..........like 1:2:4,1:3:6 and more .....
