The spacing of reinforcement is always dependant upon the STRUCTURAL ENGINEER who is designing it.
No one on this portal can give a correct answer to your query.
The correct answer is the first-line which I have mentioned in bold.
Would like to mention here some of my thoughts in connection with the query raised by you.
All the acceptance criteria mentioned in the IS codes are based on sampling done by our learned members from our fraternity.
You should definitely follow the IS codes in case you do not have the facility...
Leakage in RCC slabs reasons have mentioned based on my experiences at the site over a period of 30 years now :
Inadequate compaction of the slab during casting
Inadequate curing after casting of the slab.
Cracks in the slab after casting which connect to capillaries/gel pores.
Old structures...
For finding the percentage of silt content you have to take the measuring cylinder method only.
Sieve analysis basically gives you the FINENESS MODULUS meaning size of the particle on the sieve, it may also give you the silt content to some extent but won't be accurate when compared to the...
You have not mentioned the grade of concrete normally concrete weighs about 2400 kg/cum.*
So since you have ordered 6 cum the total weight of the concrete should be about 2400 x 6 = 14400 kg
Now when you weight the TM ( transit mixer ) it will show self-weight of TM + fuel inside the TM (...
The basic idea of waterproofing of UGWT is:
Externally so that external pollutants should not enter the tank.
Internally so that internally stored water does not leak out.
I would suggest doing the waterproofing treatment to the complete tank including ceiling as water vapor tends to stick to...
Covid-19 has been an eye-opener, in fact, COVID has been able to do the things which I couldn't have done at least till my retirement.
First of all, it has given us a good break from a stressful work environment. It has given us time to retrospect and think about one's life and family members...
Needle vibrators are chosen based on the available spacing between the reinforcement.
Columns 6" width: 25 mm dia needle
Columns above 6" width: 40mm dia needle or 60mm dia needle
Beams/Walls: you can go for 40mm dia or 60mm dia based on reinforcement spacing.
Slabs: you can go for 40mm dia...
