G.Ramalingam says:

How can calculate the Cement Content per Cubic Metre (Grade Wise) Sir, I want Detailed Calculation pl.

Sunil kumar says:

Sir,
Pls sent mix design for M25 mix using with Acc brand ppc cement.

sammi kumar says:

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

Sanjeev gite says:

Sir,
Pls sent mix design for M25 mix using with Ambuja brand ppc cement.

Rakesh Yadav says:

Please send us the RMC design mix with OPC cement with Fly Ash

kuldeep verma says:

dear sir plese send me m-25 desion while we using jaypee opc-43 grade and apex admixture

Satish Gupta says:

Respected sir please send me m-25 design while we using jaypee opc-43 grade and apex admixture

tushar g. parnate says:

Respected sir please send me m-25 design while we using jaypee opc-43 grade and apex admixture

P. N. NAIDU says:

I want to take thorough professional training in manufacturing of Ready Mix Concrete. Where can I get this training. Kindly suggest and advice immediately. Regards. P. N. NAIDU

vibhute umesh vishnu says:

marvellous experiance

K.Murali Krishna says:

why 2% entrapped air was removed and now as per new version of 10262 2009 caluculating the volume per 1 m3

Manthan Radadia says:

What are the changes to make CMD for High Volume Fly ash Concrete. Replacing Cement content starting from 45% to 65% of cement content at interval of 5%.

kiran says:

sir is it better to do project combining both fly ash and super plasticizers together or seperatly to determine strength of concrete by varying both percentage..

SUBBA RAJU says:

how to calculate the 300x300mm struips length

namo prakash says:

dear sir, plz tell me if we want to use 43 grade cement.what change it would be in mix design of weight batching and volumetric batching.plz explain in detail.
