We are thankful to Er. Raj M. Khan for sharing this information with us on engineeringcivil.com. We hope this would be of great significance to civil engineers.
If you have a query, you can ask a question here.
sir pls send the all grade of concrete mix design minimum cement content
what is the Mivan concrete pls explined to me i m wating for u r reply
Mivan is the type of shuttering used. You can say form finish where no plastering required & in this type of shuttering concrete should be having more fines.Also by using this king of shuttering you will increase your speed of work.
sir pls send M30,M35,M40,andM45grade of concrete mix design according to IS-456:2000
i want know that at which w/c ratio we can reduce cement amount while designing mix concrete for m-20
sir pls send M30,M35,M40,andM45grade of concrete mix design according to IS-456:2000
DEAR SIR, please send me full detail of design mix of M-25 grade as per INDIAN STANDARD CODE for lucknow region. thanks n regards.
dear sir pls tell me the consumption of cement for all standard concrete works as per design. plz do needful
Dear Sir,
I want with fly ash mix design and with GGBS also
with Regards
Chandra shekhar
sir,
I want reason for chocking of concrete please tell me we are pumping M-10 grade it is possible or not
sir pls send M30,M35,M40,andM45grade of concrete mix design according to IS-456:2000
How do you confirm the qty of concrete When it is loaded Transit mixture Vehicle
Dear Sir, If OPC 43 grade will be use Belongs to OPC 53 means. what ratio will get. (M25 Grade)
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
DEAR SIR, please send me full detail of design mix of M-25 & M30 grade as per INDIAN STANDARD CODE for MEERUT region. thanks n regards
