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.
what is the ratio of concrete above m35,40,45& above?
How we can made M40 mix in lab
Sir, Thanks for your kind in design mix, it is very useful for me for m30 in my profession
Hi Sir, I want to ask your opinion. For M30, is it the minimum weight of cement for 1m3 concrete is 310kg/m3? Generally, the mix design that I used for 1m3 concrete is 940(sand) : 979(20mm) : 310 (OPC). For water, 170 litre while admixture 2.32 litre were used. The type of admixture used is RHEOBUILD 1100 (HG). Superplasticising Admixture. My question is, it is a good ratio for 1m3 concrete gred 30? Product result from the used of this ratio is not very good. I’m not really sure is it caused by the concrete or workers. I really hope you can help me with your opinion. Thank you Sir.
Reduce W/C Ratio from .54 to .40 to .45 for better result.
Dear Sir,
I have received M30 mixing reports from my subcontractor. Mix proportion are 1 : 2.27 : 3.42
(a) Cement : 350.0 Kg.
(b) Fine Aggregates – Sand : 794.0 Kg.
(C) Coarse Aggregate No. 1 – 10 mm : 538.0 Kg.
(d) Coarse Aggregate No. 2 – 20 mm : 657.0 Kg.
(e) Water : 180.4 Liters
He has not added Chemical Admixture . Can M30 strength can be achieved without adding Admixture and with above proportion
Thank your
Yes it give full strength because the work of admixture not for strength there work is different
Chemical Admixture only can increases the workability not strength.
Yes it’s possible..
Sir mere ko road work me job mili h road ka work kaise hota h plz step by step bata do plz request kar raha Hu
If we use opc grade 43 cement what will be the proportion
What is mix proportion for. M30 concrete M43 grade cement
What is mix proportion M30
well i have got 1:1.87:3.37 for m30 opc 43 grade cement & no admixture used, is tht ryt answer ?
ok its 0ok thank u so much
Pl suggest mix design of water proof concrete
Sir,
Please suggest the admixture / plastisizer for design mix M40,M30 and M25 with stone dust.
Dear sir
Plz suggeste me ” what would be the proper ratio of concrete mix of M30. & M35 in the min the construction of bridge hammer head and return wall
Dear Sir
I have not much practice in grade 30 but in site we are using 30, So i need to know minimum sieve rate of the aggregate to allow the concrete.
Concrete ma m30 Kya hota h
I have a item for road work,in which M30 concrete is to be used with 40mm graded aggregate.The contractor submitted mix design for M30 where in only 20 & 10 mm aggregate is considered. As per item we have to use 40,20&10mm aggregate for mix design.my doubt are as below
1. Weather mix design is possible with 40 mm graded aggregate?
2. Should we re design mix with 40 mm graded aggregate?
3. What will be impact on strength & durability of road if we continue with mix design considering 20 mm in place of 40 mm.
Sir i wanted design mix of cube compressive strength vs cylinder compressive strength
Sir if compaction factor given how to calculate cement content
How can we convert cum in Kilogram unit
