it is a classic helpful video. Not need to do CE practical class in our college . 100% genuine .

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.

dear sir, it is really fruitful to all engineers n all new candidates pursuing their civil engg.....

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

Bhot hard bhot hard video sir mza a gya ...... miraculous video

great video...practical real world application of physics

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

Thank you sir. very much. you shows short but exact points of whole procedure.

best video on compressive strength of concrete cubes

Awesome hats off the way u explained n narrated lots of love to u

dear sir , test video is very useful.

IS VERY VERY EDUCATIVE FOR CIVIL ENGINEERING WORKS

Thank you for sharing, great info.

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.

ThankU Sir n it is very knowledgefull to every Civil Engineer.

Thanks sir i u clear all things on of the best way os teaching i Really attract from u

it very useful for me..thank you sir

Excelent description!

Knowledgeable vdo👍👍👍👍

it is very explainable videos, thanks indeed

good work sir ! may i have some documentation about those tests

Am ivankev from Kenya,I like your lessons

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

Nice vedio

thankyou sir this video is very helpful... keep on updating new process

Why are the cubes dried in water, I'd love to know!

M20 grade concrete nice video sir

which ingredients have these proportions?? (1: 1 1/2: 3) which one is cement , which one stone, etc. Also put answer in video description.

The recipe is 1:1.5:3 that is for M20 But Compressive Strength is around 39.22 N/mm2 ; i.e. for M40 Why this is so?

It's boost our knowledge as for as cube testing concern

Muchas gracias por este magnifico e ilustrativo video. Es esta proporcion (1: 1 1/2: 3) la mejor para obtener una mayor compresion?

Helped! Thanks a lot.

Nice and simple. Easy to understand.

Very good practical explanation.Thank you so much sir.

Thank u sir its very helpful for us 😊

Thank you 💟

Thanku so much sir👍👍👍 for making this great vedio

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 u Dr.very useful

Nice sir

Best on civil engineeringtak channel also..

good explanation ..thank you sir

The grade of cube was M20 (20 N/mm2) and the strength comes out 40 N/mm2......

very good explanation thanks

very helpfull sir ,upload more we are waiting

Thank you so much for the lecture. It's a great resource

Nice video

EDUCATIVE

GOOD PRESENTATION

Good

excellent..helpfulfor all

Compressive strength=compressive load \cross section area 90×1000÷15×15

what should be the copressive strength of cement concrete cube having ratio of1:3:4.5

this is nice way of knowing this experiment according to me

how to calculate the mass concrete strength without machine for example 20MPa mass conrete strip foundation

Can u show me how to do cement chloride?

good work sir.....

thanks for your teaching as

really tnx to u dear sir,

Thank you sir

sir very good testing video.

If your technicans made cubes like that on a uk site they’d be chased away.

Thank u sir for ur detailed info

it very useful for me..thank you

Safety first! No nose mask wore by the demonstrator.

Good sir

thank you so much

test concrete slump very Nice

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

Very nice

thanks so much for this

what is the observation and conclusion about this expirement?

Please make video on mix design concrete full process

Great. Thanks a lot

wanderfull education.....

I'm watching in 2021

was very helpful

For M20 grade how are we getting 40 MPa strength

Why the loading is perpendicular to top face

Thank you very much sir🙏🙏.

thanks , plz , add the compressive strength of cement mortar

wanderfull education

Thank-you this test answered my questions.

Initially it is OK.. But over a period, will it retain all it's original strength?.. However the clay brick is time tested.

Sir can u please upload aci code for aggregate testing,diff.tests for cement and compressive strength cube test of cement.

Namaskar ji Please give video on cement miortartest

Fines are missing, no plasticity! You will never have a chance to use such a "concrete" with still rods. Welcome to the Stone Age!

Thank You so much Sir

bahut Acha

Terima kasih buat infonya,,,🙏🙏🙏

useful

thanks very clear

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?

Megapascal and N/mm^2. and total weight handling and time duration ka ek mix graph kya hoga Tensile strength key saath youngs modules Yani sab formula ka ek corresponding correlation nikalo Ya sabko mix karkey ek maha formula banao to hum theory of evolution everything ki taraf badleingey 🕉🕉🕉🕉

Thank you sir for help me

Thank U sir

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?

Thanks

11:10. ....How it's come 90 ×1000. As A force ??? How 90??😢😢😢 .? Don't get a shortcut please.. explain how it's come to ????? Plz explain in reply .. brother🙏🤗
