Concrete block of 150 x 150 mm sq of Grade M20 is suppose to have compressive strength of 20MPa but this practical video shows it has a strength of 400 Kg/cm sq i.e approximately 40MPa which is quiet impressive.
Please i just want to understand the last statement before taken the concrete cube specimen out of water talking about 24 hours before testing. I need to understand that lines of stament. Thanks.
40 mpa is target strength decide for perticular characteristic strenght .. if there happens to be bad workmanship , high w/c ratio will least get 20 mpa
Goodday sir , I'm watching from Guyana and began this lab an having some problem with the satisfactory or unsatisfactory failure.DO not know how to identified them?
In real case is sample to be collected from Construction Site during its construction (i.e slab)or 1st we prepare in lab then after we get results we start in real construction filed? simply testing is done in lab before construction or during the day of construction sample is taken to lab?
which equipment is used to compact the concrete filled in moulds? what is the ideal weight/area in kg/cm^2 for M45, M30, M15 grade concrete respectively? How much load is being applied per cm to the concrete cubes surface if a manual, lever arm operated Compression Testing machine is used? In automatic Compression Testing Machine, as mentioned by you, the load transfer rate is 140 tonnes per cm. Please correct me if I am wrong. Also if the mixture is taken according to 3 moulds quantitatively, then if the readings aren't 15 plus or minus of each other, the whole mixing process has to be done again?
Thank you. that was a great info. ignore those repeater id*ots saying about safety wherein this is just a very small scale experiment. Dirty hands are sign of good labor anyway.
raughn jeraiah medel I’m here 4 years later wondering if the operatives still have skin on their hands or has it been gradually burned away by raw cement ?? Just a thought.
it is a classic helpful video. Not need to do CE practical class in our college .
100% genuine .
I seen many vedeo regarding concrete cube test but your clip are most preferable
Thanks a lot for uploading such a valuable vedeo.
Sir your videos are very usefull for civil quality control lab engineers
dear sir, it is really fruitful to all engineers n all new candidates pursuing their civil engg.....
Manvinder Singh Ra
Awesome hats off the way u explained n narrated lots of love to u
Thank you sir. very much.
you shows short but exact points of whole procedure.
Thanks sir i u clear all things on of the best way os teaching i Really attract from u
Bhot hard bhot hard video sir mza a gya ...... miraculous video

It can be
Please visit #civiltechclass
Your ans in this video
Yes i also testes on m20 and i got 480 kg
Please i just want to understand the last statement before taken the concrete cube specimen out of water talking about 24 hours before testing. I need to understand that lines of stament.
Thanks.

thankyou sir this video is very helpful...
keep on updating new process
Thank you for sharing, great info.
Helped!
Thanks a lot.
great video...practical real world application of physics
very helpfull sir ,upload more we are waiting
best video on compressive strength of concrete cubes
Nice and simple. Easy to understand.
Am ivankev from Kenya,I like your lessons
good work sir !
may i have some documentation about those tests
Thank you so much for the lecture. It's a great resource
good explanation ..thank you sir
Muchas gracias por este magnifico e ilustrativo video. Es esta proporcion (1: 1 1/2: 3) la mejor para obtener una mayor compresion?
Thank u sir its very helpful for us 😊
it very useful for me..thank you sir
It's boost our knowledge as for as cube testing concern
Thank u Dr.very useful
Thank-you this test answered my questions.
Can u show me how to do cement chloride?
how to calculate the mass concrete strength without machine for example 20MPa mass conrete strip foundation
thank you for your technical suport
Thank-you for the wonderful video but I didn't understand how to note and solve readings of it. Make the video completely. Please sir
Excelent description!
ThankU Sir n it is very knowledgefull to every Civil Engineer.

Goodday sir , I'm watching from Guyana and began this lab an having some problem with the satisfactory or unsatisfactory failure.DO not know how to identified them?
very good explanation thanks
Thanku so much sir👍👍👍 for making this great vedio
Very good practical explanation.Thank you so much sir.
what should be the copressive strength of cement concrete cube having ratio of1:3:4.5
it very useful for me..thank you
dear sir , test video is very useful.
it is very explainable videos, thanks indeed
GOOD PRESENTATION
Thank u sir for ur detailed info
In real case is sample to be collected from Construction Site during its construction (i.e slab)or 1st we prepare in lab then after we get results we start in real construction filed?
simply testing is done in lab before construction or during the day of construction sample is taken to lab?
thanks so much for this
what is the observation and conclusion about this expirement?
Thank you 💟
How much plus mines (+ -) is the strength of cube grade M 25 concrete.
thanks ,
plz , add the compressive strength of cement mortar
sir i have a question plz reply
what is the mean of 140 kg /cm^2/min
Why are the cubes dried in water, I'd love to know!
thanks for your teaching as
Knowledgeable vdo👍👍👍👍
thank you sir for helping me
good work sir.....
What is the astm C39M for compressive strength
test concrete slump very Nice
Sir can u please upload aci code for aggregate testing,diff.tests for cement and compressive strength cube test of cement.
nice 1 sir and thanks to ur team also i hope urs all giving us to more knowledge about How to give good Quality and How to test materials

Exactly 💯
The load applied At the rate of It's 140 kg per cm sq

Thank you very much sir🙏🙏.
sir very good testing video.
Dear sir please help me what is weight of loading in cube testing per second? Please reply sir
IS VERY VERY EDUCATIVE FOR CIVIL ENGINEERING WORKS
this is nice way of knowing this experiment according to me
I need a job please help me sir
Please make video on mix design concrete full process
sir , i like your video much. i want to made quarry stonedust cubic . can you please tell me the detail mixture for that ... i would be very thankful
Best on
civil engineeringtak channel
also..
Great. Thanks a lot
Sir is there some new topic about concrete mix for m.tech research work
It's just an awesome explanation, Sir, thanks indeed.
sir...what happens to strength when the compaction with tamping rod exceeds 35 blows?
TILAK SURYA VARMA PASUPULETI nothing. The standard says MINIMUM of 35 tamps per layer. so more won't affect the strength but less will.
was very helpful
really tnx to u dear sir,
If you recieve 1000 cubes per day, what you do? How u curing thise cubes?
How to decide quantity of water ?
thank u very much
Why the loading is perpendicular to top face
thanks very clear
Compression testing machin ka RAM diameter kitna hota h sir
excellent..helpfulfor all
Not add the admixture sir
Thank you sir for help me
The grade of cube was M20 (20 N/mm2) and the strength comes out 40 N/mm2......
Nice vedio
Thank U sir
useful
M20 grade concrete nice video sir
well done
Sir how meny amount of water add.?
Thank You so much Sir
thank you sir
now i have the experence with slump test
Is code used in this test ?
Terima kasih buat infonya,,,🙏🙏🙏
How much water has been added sir.?
wanderfull education.....
For M20 grade how are we getting 40 MPa strength
Thank you sir...
