i am using M30 Concrete mix on site. but i am not getting the required strength. i am using 1:1:2 ratio. i am not putting any Superplasticiser into the mix. i am using vermas of dimensions 12?:12?:15?. can you suggest the rite mix ratio to achieve the required strength. i am using cement 43 grade. thank you for your help in advance.
What should be the compresssion strength of M30and M45 grade concrete in seven days with and with out admixture. Cement used is 53 grde PPC
What quantity of 6″ or 9″ block can be produced from 20 tonnes of sand?
What is the difference between tare and bitumen ??? and also specific application of tare and bitumen ???
as we use thumb rules in design for RCC beams e.g.100mm depth per r.m. of span.what is such type of assumptiom for columns and rcc footings in respect of sizes.
what is grade of cement? e.g. 53 grade does it is 53megapascal? pl.make it convenient to understnd in details.
yes,grade of cement shows the compressive strength aquired in 28 days in megapascal(MPA)
Dear B.L.sharma,
Grade of concrete C40 means the compressive strength of concrete. The unit of mPA which means N/mm2.
what is hydraulic jump how it reduces the energy of water..?
When liquid at high velocity discharges into a zone of lower velocity, a rather abrupt rise occurs in the liquid surface. The rapidly flowing liquid is abruptly slowed and increases in height, converting some of the flow’s initial kinetic energy into an increase in potential energy, with some energy irreversibly lost through turbulence to heat.
The use of hydraulic jump in hydraulic engineering is not uncommon
and the creation of such jumps has several purposes:
(i) Its main aim is to perform as an energy-dissipating device to
reduce the excess energy of water flows. When water flows through a jump, it experiences multi-directional flow so that energy dissipation results.
(ii) The jump generates significant disturbances in the form of eddies
and reverse flow rollers to facilitate mixing of chemicals.
(iii)During the jump formation, considerable amount of air is entrained
so that it helps in the aeration of streams which is polluted by
bio-degradable wastes.
(iv) It enables efficient operation of flow measuring device like flumes.
Hi Sir.. I m Pre-final year student doing Civil engineering.. Can u plz help me by giving suggestion for my final year project(design).. I ve no idea wat subject i want to choose concrete or steel or transportation engineering.. Kindly help me sir… i need simple project… Waiting for ur reply… Thank You sir.
DEAR JESSI. GO FOR CONCRETE DESIGN. DRAMIX CONCRETE WILL BE GOOD TOPIC
while desigining concrete mix do consistency of cement is considered? pls reply to my answer i will be waiting for ur answer
What is the difference between column drop and column capitol?
What is the logic behind using subbase material consisting of, say below 70mm size?Why can not we use larger size material?
Sir,
I just want to query if a g-3/8 gravel is structurally acceptable as an aggregates for a beam with ledge carrying a heavy load of precast slab with 16 tons per pc.Pls. advice

how to design water bound macadam by irc 19.what type of calculation are require for this design.any such format is avialable?
my question:
please explain how ggravity fed system is fed onto jet grouting curtain wall?
explain what is grouting curtain wall? plz xplain thru pictures if possible..
For industrial shed-What should be floor specification when floor is prone to temprature exposure upto 1000 degree occasionaly and heavy traffic movement. Like furnace area of casting metal sheds.
whts the diffrence between tantion zone and compresion zone…how can i put the main steel bars in slab or any area….how can i calculate the steel.it will be main steel in that area….plz tell me abt that….thanking u….
How can pile is work it is a compration member or tention? or only simpal load transfer member?
To kaushik jadav,
Piles can be designed as tension and compression members. For supporting heavy vertical loads like buildings, it is usually deisgned as compression members.
For piles in marine piers, it is designed as tension member to withstand the horizontal loads of berthing forces.
is there any design variation in compression,tensile pile…and reinforcement details remain same or will it vary
pls send me few topics related to concrete for phd. work.
Sir am working in a private firm at kerala.v r thinking to use superplastizizer.if v use superplastizizer, hw much it will reduce the concretes cost ?
