Frequency of Sampling Of Cubes I How To Do Concrete Cube Test at Construction Site I Cube Frequency

Hello Everyone welcome to the knowledge of China Let's learn together The topic of today is the Frequency of Concrete Cube Samples for Compressive Strength of Concrete When we do concreting The quantity of concrete how many cube samples are needed we will discuss that next Main aayaliye a video about concrete cubes cube mold cube test and compressive strength The first video is What is compressive strength What is its purpose What is its importance What is the second video What is the procedure How do they perform the test What are the results What's available Then can we make a decision So you can watch this two-minute video You will also find a link in the description and in the button as well This way you will get an idea What is the importance of the concrete cube test What is the procedure How is it done And what are the various results obtained with it We will watch today 's video how much concrete is needed how many cubes should be taken We will check the details how much quantity is there How many sample cubes do we need How many cubes in terms of number how many cubes does a sample contain We will look into the details This is a practical video on cube casting In this you can see that these cubes are being cast in three layers And this is the tamping rod It has a diameter of 16 mm and its length is 60 cm Also it is cast in three layers It is called 35 blows In the third layer it is called 35 blows 35 strokes are counted They cast this cube with it The cube size is 150 mm by 150 mm by 150 mm This is a 16 mm diameter tamping rod This is filled in three layers This is a table here we can see for how much quantity how many cubes should be taken It has a sample table The first column is quantity of concrete in cubic metre Then comes number of samples to be taken After that Cubes to be cast for a 7-day test Then cubes to be cast for a 28-day test After that otal number of cubes to be cast Or remarks Toh they have started First 1 to 5 cubic meters of agar concrete is there so we need to take a sample from it A sample means that in one sample there are 3 cubes A sample means 3 cubes to be cast After that in this for 7 days it became 3 And after that For 28 days 3 So what is the total number of cubes 6 numbers We will check after that For 6 to 15 cubic meter concrete we take 2 samples 2 samples then from these 6 And For 28 days 6 Then the total numbers became yours 12 numbers After that 16 to 30 cubic meters For 16 to 30 cubic meters we take 3 samples As such 9 have been taken And otal 18 have been After that 31 to 50 cubic meters For 31 to 50 4 samples are taken These will be 12 28 days later it will be 12 How many cubes are there in total 24 numbers Now after this 51 cubic meters to 100 cubic meters Also I say and above to and whatever comes next will remain above For all of you total 4 plus 1 we take 4 samples plus 1 sample We take this much in which 3 7 days3 28 days It will come 12 plus And it will also come 12 plus 3 Total how many will come 24 plus 6 Is equal to 30 number 51 toabove No matter how many for it each sample must be added Total 30 cubic meters For example if our concrete quantity Concrete quantity 64 cubic meters If this is 64 cubic meters then how many total cubes should we take as a sample Total cubes 15 plus Is equal to 30 number30is Lena That if concrete quantity 125 cubic meters here How much total cube do we need Total cube 18 plus 18 Is equal to 36 numbers This is the main one to be placed in the dehyan a sample equal to 3 cubes And it has to be tested for 7 days One josra sample need to test for 20 days And this its the strength these three average will be taken the strength that comes Where there is strength it must be considered So friends we saw today the frequency of cube samples how much quantity for concrete how many cubes do we take In today's video let us know how you liked it please comment If this is your first time I have seen my channel so my channel please subscribe And the bell icon on the side press it Take my coming all videos to notification to you can be received Thank you
