If you have a query, you can ask a question here.
Thanks, A lot of Thanks!
thank you sir.
Thanks a lot for your
Knowledge distribution
Very very thank you sir. I need M-70 mix design pls.
Check this
https://www.engineeringcivil.com/concrete-mix-design-m70-grade-of-concrete-opc-53-grade.html
Sir,
Could you please tell me if the concrete mix design done with OPC 43/53 grade cement and fly ash is done with which IS code and can be govt. approved.
Surjit Singh
Respected Sir,
Sir,please send me the mix design of 150kg/cm2,by using Fly ash, Stone dust,fine/coarse sand, cement/Lime, gypsum. for bricks & blocks.
Please do the needfull;
Sir ,Pl Give me Design mix of Flexural strenght conceret using 400 kg of cement in per cum
Sir,
I want to ask, what are the concrete grade 15, the same way as mixing hand using a ratio of 1:2:4 of cement, 2 sand, 4 stone
Dear sir,
please provide us the thumb rule of all construction activity so that an fresh engineer easily do the work at site.
Sir,
pls tell me mix propotions for slab & pillar(18″*18″)
Dear Sir
I would like say Thank to you Sir for a detail information of this design M-15 Il appriciate what you give a knowlrdge it use to go as far as I cant grab in this course, Thank to this site that we can shared a information together..
Regards
Helmi
Thank You for all..
sir,
i am an non engineering student but with its leaning.Your info on the design mix of concrete is of immense help since we always get trapped in the wrong footing when it comes to details.Thanks a million nevertheless.
Sir,
I am really thankful to you by providing this information…It helps me a lot for my knowledge..
sir,
anybody could suggest a mix design for M15 grade with 100 mm slump with polypropelene fibre
Sir,
Indeed,it`s an exhaustive information 4 knowledge in construction tech
. Thank u very much.
Thanks & regards,
-Satish Kalaiya
Sir,
Can you pls advice the mix design for a) Hollow concrete block
b) Shotcrete in EVG 3D wall system ?
Thank you
Shashi
sir,
pls tell me hw can be check the strength of concrete cubes.
what is the mix proportion for M15 (10mm coarse aggregate)
sir we want compressive test at least 320 kg for 7 days result please suggest us the concrete mix design for the same.we will used redimix concrete
what should be the comprehensive strength of M15 40 MSA after 28 days curing ?
