Rajneesh Jindal says:

Dear Sir
What is (MORT&H 1700-3 A)?
regards
rajneesh jindal

tapan Banerjee says:

What is SSD condition? Please explain since it help me a lot.

Dr K.Srinivasa Varma says:

Saturated surface dry condition.SSD condition will be considered in Concrete mix design

rajasekhar says:

plz give design mix for PORTLAND SLAG CEMENT

suyash dubey says:

What is the content of sand & coarse agregate in M-25 & M-40 concrete

Arun says:

I want detail about civil construction works

Arun says:

Daily I want detail about civil construction works

Amrendra Kumar Singh says:

Please give design mix M35&M45 cement used opc53 grade sand 3zone

Amrendra Kumar Singh says:

Sir I want detail silt&clay diffrence

Dr K.Srinivasa Varma says:

If the particle passes through 75 micron IS sieve,that can be silt or clay.If the particle size is less than 2 microns it is clay

amol says:

sir how can we define cement content for M30 & M40 Grade concrete.

ashish patil says:

sir, how can we take detail mix design of known quantities of materials for m25 grade of concrete such as cement 403kg/cum, C.A. 0.89cum and 0.44cum of sand per cum of concrete

SALAMA says:

hi, currently i have to perform a job of casting concrete M25 BUT the required strength are @7days must be 22 and @ 28days not less than 28N/mm2 … what is the best mix ratios by weight/Volume to mix 1 bag of cement =50kg.

rahul says:

Sir, please tell me about a curve graph of cement concrete cube.

pankajakshi m g says:

Hw do u take up the value of target mean strength….?
wid regards..

sanjay kumar says:

Is 1:1:2 closest to M25 grade concrete using PENNA OPC 53 grade cement?

Jitendra Kumar Behera says:

Dear Sir, in M-25 opc-43 grade concrete, what percent water is abserve?

i am vijay says:

Can u explain me i want to quantity material for m20,m25, m30

p.senthilkumar says:

sir please tell about M25 GRADE OF DESIGN MIX CONCERET .400KG \PER M CUB

ganesh kumar says:

dear sir
how to calculate mix ratio concrete with cement content

Ezhilarasan says:

what is the mix ratio of M25 Grade of concrete?

Ankit Shrivastava says:

Thankyou for explaining us But I have a doubt that at some places people are using 1:1:2 ratio (nomnal mix) for finding cement, fine and coarse aggregate. Can you tell me which one is correct or which method should be used and when

Abdelrahim says:

Thank you for the information .. I would like to know the same m25 for natural coarse aggregates ?
