kumar kamble says:

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

Dharm Pal Raseela says:

Sir, if OPC cement is not available than can we use any PPC cement for mix design M-25 for testing

Dr K.Srinivasa Varma says:

You have to redesign your concrete mix.Specific gravity of PPC cement,strength,workability,setting time will vary.

Pardeep Kumar Verma says:

I want to check cube strength. But I don’t know how i can calculate strength
M-25. My load on cube is 725 Newton. But how calculate M-25
Please tell me with examples

k.srinivas rao says:

sir pl send M20 AND M25 AND M-30,M35 Design with fly ash and cement

Deepti Singh says:

Sir why this mix design procedure differ from that of finding out the material quantity through ratio methid i.e. 1:1:2

Deepti Singh says:

If we check out the ratio here it will come about 1:2.34:4.2

Lokesh Laxmilal Lodha says:

Deepti Singh
Yes Your Question Is Correct. See The Ratio Which Has been Know to us is Completely Bassed On Trial & Error Based It Is Not Defined By Is Code As for General Purpose We Adopte The Trial & Error Method Which as we Know But for Specific Work We Should Go through The Mix Design Which would Be Different From The Ratio.
Thank U…
Happy 2 Help U…!

sree vidhya says:

How the water amount is reduced to 186 litres to 138 litres,give me the brief explanation

Mane Rupesh says:

What’s m 25 pl.explain propration c+s+khadi+water

raj says:

how to calculate ratio actual

ramraj thakur says:

please explain method for determination of mix proportion by 1 cum quantity.
as 1:1:2.

pavan says:

Sir how is estimated water content been calculated

thanvi k j says:

please issue if possible contact no of approved concrete testing lab in jodhpur (Rajashthan area or near by area

Anita Cyriac says:

Dear sir
Can you please send me concrete mix design of m20 if I am adding 30% and 50% of an admixture.

Meena says:

How can we determine water content for 65mm slump

rggohil associates says:

dear we wont m-25 / m20 design mix for projects volume syt. plz. send

thanks

ks chandna says:

The mix design is for maximum size of aggregate upto 40 mm are readily available.In mass concrete the maximum size of aggregate is considered as 80 mm for M15 and M20.The grading of 80 mm size aggregate is not available .Please provide mix design of A80 M20.

I.RAMESH says:

m60 mix propotions to giveme

sammi kumar says:

Plzz sant a design mix M25 and M30 with acc cement brand.

arvind says:

how the proportion of CA 20mm and 10mm is decided?

Er Abhaya Kumar Samal says:

If OPC not available,which cement can used for design of M20,30,40 and above
