I want which software package is good for civil engineer
I want to know weather mixed sand ( sand is mixed with fined gravel) is advisable for roof concrete
sir………… as there anychange in get optimum butmins content with marshall procedure as i know by averaging the 3 ac contant say at highest unit weight, heighest stability nd maidin air void, las week some ask me a question about that when i say as per MS-2 he say update urself please let me update.
hi;
i want SOP for quality control lab; if any one have pl send me
Sir,
I would like you to detail me on sustainability of building materials in construction projects.
Thanks Alot.
in the absence of cube strength results for finisheb buildings whether rebound hammer test results can be taken as accurate.If rebound hammer gives positive results and pulse velocity meter results falls below 2.5 Km/sec whatis the ultimate coclusion on concrete.
What is the best formula to find the tensile strength value from the splitting test. there is a linear formula and the formula that we include the width of the strip?
Thanks for your time
What is the dilation angle of concrete and how to calculate it?
Thank you

Dear Sir,
I have a couple of queries regarding bricks and blocks manufacturing:
1. Different Mix designs for Pavers
Pavers are graded as M10,15,20 etc. and also the standard mix design for this is available.
But if we use the same design to manufacture the blocks, the product is not cost effective.
So i want to know what are mix designs in practical to achieve the grades M10,20 etc. and at the same
time making them cost effective?
Following raw materials are available with us:
a. Crusher Dust
b. Grit (any size)
c. Sand
d. Cement
Also, what should be the mix for the 5mm layer of color on the bricks?
By what name do we get the color powder?
2. Use of Salty Water
As i have read across the internet,Salty water is not good for concrete products, especially in case of RCC as it erodes the steel structure.
The boring in our factory has salty water.
Now,if we get potable water from outside then our product will not be cost effective.
How can we use this salty water?
Is it ok if use sweet water for mixing and satly water for curing?
Is there any admixture which can neutralise the salts in the water?
3. Mix Ratio for Fly Ash Bricks
I have also heard of Fly Ash Bricks which are lighter and have a good strength.
What is the ideal ratio for manufacturing of fly ash bricks(with above mentioned raw materials)?
4. Use of CaCl2 to accelerate curing
I have read about CaCl2 acting as an accelerator for curing.
Is it true?
What purity of CaCl2 and in what proportion should we add in the mix?
5. Use of Lime and Gypsum for manufacturing of bricks
Can we replace cement with lime and gypsum in manufactruing of bricks?
We generally add 7% cement in our bricks.
How much Lime and Gypsum should we add to achieve the same result?
What is the purity of lime required?
6. Bricks using Dust, Sand, Grit and Cement/lime-gypsum
What is the mix design for bricks without fly ash?
How do they rate in comparison to fly ash bricks?
Are there any indian standards?
7. Factors to be considered for new mix design.
How to design raw mix for a particular strength?
8. Compressive Strength of Hollow Blocks
recently i had sent the hollow block produced at our factory to one of the testing labs.
The put the hollow block upside down i.e. hollow portion down and flat on top and checked the compressive strength
Is this the write method?
Because the hollow block masonry is done with hollow portion up
So if we check the strength with hollow portion up we have fill the voids with sand, right?
Await your reply.
Thanks & Regards,

I am an estimator being asked to establish how much “Counter Weight” we will need on a site in UAE that contains shabak. I have no idea how to calculate this but the other petrochemical sites around us have raised their sites to 6 -7 meters above sea level. This is right along the coast. Any info???
whats the best project to do in concrte mix design basics?
thank u
Sir,
What are the design consideration taken in designing an Aqueduct?
Thank You.
I’m in 2nd year of b.tech. in civil engg. I’m confused in choosing gov. sector & private sector for job. Plz tell me which one is best. Also tell gov. sector jobs. I also want to join IAS.
You first work in private sector job for 2 years for gaining experience and also keep try for govt jobs by writing competitive exams. U will have good future….
please tell me the IS code use for the mix design of high volume fly ash concrete or any alternative
