I always appreciate people who come forward and try to help others.So in case you feel you have any content that is of some relevancy and usefulness to other civil engineers be it a presentation, report, any file, videos, pictures etc do mail to me at

Thanks for being the part of your very own website
Mr.Vamsi, please try silica fume (micro silica) for achieving high strength (M-40) concrete
how do we calculate the actual dia of TMT rods?
sir
pls tell me how to find the the quandity of aggregate & cement in M15(1:2:4). Is it any equation.for finding the quandity of any typr of grade
Qty. of materials
= [15.2/(1+2+4)] = 15.2/7 = 2.17
1(Cement):2(Sand):4(Aggregates)
Cement = 1X2.17=2.17Bags
Sand = 2X2.17=4.34Cum
Aggregates = 4X2.17=8.68Cum
OK?
Hey, I m a civil engineer. Currently working as an engineer in NTPC. I want to start working as a contractor. Is there any problem in getting payments if I approach for contracts in Railways and CPWD.
I am M.Tech (str.engg) know i doing project for the god project i sercheing pl give me as nise project like in steel str.
I am a civil engineering B.tech student and i need some information about pond ash related with concrete because i am preparing a project report about pond ash so please give me that.
i want an topic fof project i am in third year diploma in nashik
sir I m doing a project on use of silica fume(micro silica) for achieving high strength concrete(M 40).I need some imformation to be shared on this topic.
Water proofing & cracking in external plaster these are big problems in the building maintainence. To avoide this problem if any new methadology or techinwque if developed I will like to apply the same for todays work.
Awaiting the replay.
Thanking You
i am going to join a enginnering college but i know nothing about it.
what type of enginnering should be give the first priority?may u all
can u please tell me what type of enggr has more scope in
professional life?
thank you.

sir i am student of nit trichy. i try to find out the initial setting time of lime but i cann’t get the result after 48 houre the needle go fully inside . according to me my procedure is wrong (i do as like cement)so plese tale me what is the procedure and who much time take lime to initial set.
Initial setting time purely sepends on the cement content.Normally in sites (Exposed) it starts in 30 min after pouring.
In your case its not happening even after 48 hrs!! seems to be quite strange.Give more details on how to do u do so that you can get better answers(including mine).
What i need is just basic design of retaining wall and Dam construction with full explanation of symbol and definition. I will be really very grateful if someone help me or send me a a full design calculation Take it in light sprit.
Find an engineering firm and make them accountable for their calculation otherwise you may face the same situation like Dubai 6 story block collapse.
Water proofing & cracking in external plaster
More detail req. to answer.What type of water proofing? Is it in roof?
Plaster crack unavoidable but u can minimise by introducing patterned marked lines when the conc/morter wet.
actual dia of TMT rods
vernier calibre to certain extend.
Why u need to do becas most of the rebar bundles are marked.If u reaally want to check,cut a meter bar and weigh.
what type of enggr has more scope in professional life
It differs with time and country where u are going to work.
You may not work what u have studied (most of the time) also may not get a chance to use what u have studied.
If u inclined to some engineering then u select that.
Best of Luck.
Is it any equation.for finding the quandity of any typr of grade
To my knowledge “NO”.
All the mixes are with certain parameter of Metal,sand and Cement.Only trail mix and cube tests can reveal the correct strength.
This is the industry standard most widely used.
Hi there,
I’m actually a mechanical engineer but have to do more civil work. My question, what is
meant by G0 – 9 in terms of soil grading? eg. I can get gravel with G4/5 grading to repair
embankments of soil dams for sewerage purification ponds. Is this grading good in
terms of gravel to be compacted and how does this ‘G’grading/scale work.
Your help/explanation in this matter would be greatly appreciated.
Hi there,
A rather tricky situation I have. I have to de-sludge sewerage ponds. These ponds vary in
size from 2000 to 8000 sq m. and there are about 18 of them. What would be the fast most
effective method of getting this sludge out. ps. I have tryed to pump it out with large sludge
pump & are now trying front end loader + tipper, but neither work very well. ( pump too slow
& front loader damages pond base & battle to move around on clay bottom of ponds)
The sludge is very soft, consist of + – 35 to 45% water.
Would love to hear from anyone having a solution. Thank you
Kind regards

i want to know disining prosses of water treatment plant.you can halp me.
We specialise in water purification, also maintenance and construction of plants…what do you mean by disining?
Designing means to provide sizes, dimesions of all units, its steel qty. dia. of bars etc. and also hydraullic terms such as velocitu to be kept etc.
sir how to make quality cement bricks(mix)
