The new Solani aqueduct on Ganges canal Roorkee was built with prestressed concrete which allows for longer spans and a simple more robust design compared to old bricks, lime- surkhi mortar masonry arches of the old aqueduct, in which 8.5 crores bricks were used, while iron railing used in the sides of two lanes were imported from England. This is interesting to note that materials bringing those days on ship from England to Indian ports take 6-10 weeks via the Suez canal or 3 to 6 months via the longer Cape of Good Hope. Calculate in it also time taken on road from Indian ports to Roorkee.
After retirement from University of now IIT Roorkee I joined M/S Roffe Construction Chemicals Pvt.Ltdd, Mumbai as it’s Chief Concrete Technologists afterwards I became it’s one of the Director.

For the contractor of above aqueduct I designed M-40 grade of concrete with Roffe superpladticizer. Those interested may read my paper by visiting Google site and log in; Civil engineering portal The Ganges canal by Kaushal Kishore.
I had designed numerous concrete mix design almost all cements of India in this I find Utra Tech cement as one of best cement OPC and PPC both With Ultratech cement I had designed numerous concrete mixes from ordinary strength to M-80 grade concrete, self compacting concrete, shot crete concrete, fibre reinforced concrete, fly ash concrete and more There is life after retirement and after retirement I worked for 30 year’s which includes in free time working in home research and testing laboratory and numerous construction sites visits almost all India and outside India. At my age of 92 years I still work for 12 hours daily.
I had never worked for money. In spite of doing so gigantic work what to say about car I even do not have 2 wheeler not any of my house not a single inch of land in this world only pension from IIT Roorkee and few clothes
sir,is there any project report on residential building using prefab technology
I m in 3rd year of be civil my notes will not complete. so please send me RCC notes by mail.
type of pile foundation
I think you should meet to your alumines…..
a graduated civil engineer.i love my field & really want to practice it. i need more experience
Given a 90-degree triangular weir cut across a channel with edges sealed to prevent leaks around the plate. if the measure the height of the water over the weir reads 150 in day and 170 in the next day. What the estimate of the flow over the weir in liters per second and in liters per day
how to calculate the estimate of shuttering or what is rate of shuttering in sq.ft. & how it made plz. send all on my mail.Thanks
In Raft footing when the 75% of area of foundation cover & load of structure is very high, there is both sagging & hogging Bending Momment Takes place. upper steel takes place sagging bending momment & lower steel takes place hogging bending moment due to soil upword flow ie. Invers of Terrace slab
What is the fines grade for plastering sand ?
dear avinash no one can understand concrete how it behave in different type op conditions, if your m45 cube gave 52 mpa strength of several samples at 7 days its too high. we can imagine up to 100% strength if our quality control is excellent. you may reduce your cement content.
Dear send me this mix design.
if really happens it is so good.
ur creator.
Hi people anybody please help me by suggesting a industrial waste which i can blend it with self compacting concrete to increase its strength. Normally a SCC has flowability advantage only, but by this experiment am adding one more advantage like increasing its durability.
I want all civil eng. IS code
plz tell me civil engineering strengths…!!
i have to know some procedures about night time slab concreting?
Please tell me via email name of books written by sk duggal.S K Duggal, currently a professor in the Civil Engineering Department, Motilal Nehru National Institute
Let say I have a slab which surround it with 4 beams and columns at corners, and I will stop casting concrete slab at those beams too. Since I have other span of slab which will connect and cast later to this span, do my beams should stop cast at column or further and if yes then how long should I cast the beams after edge of column?
i want to know the new technology used in civil engineering and construction
I m a civil.engineer student
sir i want bridge engineering viva questions and answers.
I want to know which one bar will main bar in a raft, long span or short span
