If you have a query, you can ask a question here.
Dear sir,
Please send the mix proportion ratio of 1 Cubicmeter concrete. Slump height should be 110mm.
cement-310kg,fine aggregate-756kg(dry weight),corse aggregate(20mm-849kg,12.5mm-330kg),water-155kg,admixture-3lit
Dear Sir,
Please send the quantity cement,sand,aggregate and water for deffrent Mixture.
pls send quantity of cement sand & aggregate of deffrent
Please send the quantity cement,sand,aggregate and water for deffrent Mixture.& concrete mix design Formula
pls mention ta proportion clearly
is it possible to premix coarse aggregate and fine agregate in 1 cum bags and use it later after 15 days and mix it with cement and water at the time of concreting?
Please send the quantity cement,sand,aggregate and water for deffrent Mixture.& concrete mix design Formula
Please sent the quantity cement,sand,aggregate and water for deffrent Mixture.& concrete mix design Formula
How can calculate the Cement Content per Cubic Metre (Grade Wise) Sir, I want Detailed Calculation pl.
Sir,
Pls sent mix design for M25 mix using with Acc brand ppc cement.
Plzzz sant a mix design M25 and M30 with acc brand cement.
Sir,
Pls sent mix design for M25 mix using with Ambuja brand ppc cement.
Please send us the RMC design mix with OPC cement with Fly Ash
dear sir plese send me m-25 desion while we using jaypee opc-43 grade and apex admixture
Respected sir please send me m-25 design while we using jaypee opc-43 grade and apex admixture
Respected sir please send me m-25 design while we using jaypee opc-43 grade and apex admixture
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
marvellous experiance
why 2% entrapped air was removed and now as per new version of 10262 2009 caluculating the volume per 1 m3
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%.
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..
how to calculate the 300x300mm struips length
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.
