DETERMINATION OF STANDARD DEVIATION OF CUBE COMPRESSIVE STRENGTH
Вставка
- Опубліковано 28 сер 2018
- In this video , I had tried to give the procedure of finding out the standard deviation of given cube compressive strength.Standard deviation is the measure of dispersion of a set of data from its mean. It measures the absolute variability of a distribution; the higher the dispersion or variability, the greater is the standard deviation and greater will be the magnitude of the deviation of the value from their mean.

Thank you so much sir ji... it was awesome explanation and thanks a lot for this video.
Excellent sir...long time I was searching for this concept with table..
Keep watching
Very clearly presentation.keep it up.
Keep watching
thank you.. for good knowledge.....
Thanks 🙏 you have done great job 👍
So nice of you
Very Usefull Sir. SIR ,Pl. Share video of Gradiation of aggregate
Good demonstration
very good sir ji
very good sir
Thanks for good information
So nice of you
sir thank you for uploading videos. sir what if we are testing for only 3 cubes of same component ie .coloum or beam then what in "N" in this case
N means number of sample, does not matter whether it is column or beam.
Sir hme characteristics strength aur Target mean strength me kya difference hai plz btaye
Really very useful video
Thanks a lot
@@HIGHWAYGUIDE sir kindly prepare a video of HM plant and rmc plant
From where did you got those excellent, good and fair values. Share the reference code.
According to Hemsworth
Sir I have seen in this video that some cube results found 45,48,51..etc ... Is it possible for M35 concrete??
Yes
Sir I want to know ..from where we get A.M value = 42.51??????? Plzzz
Very nice explanation 👌 u clear my all doubts
Glad to hear that
Sir, current margin 1.65 kaise aaya?
Nice explain
Thanks for liking
Thank you sir 🙏
Most welcome
Sir . Standard deviation design mix k pehle practically karna jaruri as per IS code 30 samples=90 cubes or as per is code table se Lena 3.5,4&5 as per req.
Which is better ,
Not necessary
If I have 20 set cube data reading per day then how it calculate sir plz tell me
Same procedure will be followed.
Thanks🙏🙏 sir
All the best
Sir 5:18 pr limit ka koi reference code h??
Sir S.D ka jo range(2.80-excellent) aapne liya h wo kha se liya h....mere ko client puchh rha h...
According to Himsworth
Sir what is (N-1) OR N... WHY DIVIDED BY 17 INSTEAD OF 18
Sir, where it is mentioned, very good, excellent etc. Pls guid me,
According to Himsworth
Thank you
You're welcome
Sir 2.8 excellent wala hai aap kha par hai
Minimum samples to be taken 30 nos but you have taken only 18 nos sample. Is it valid?
Yes
We are following you from beginning of your UA-cam channel
Please tell me about
This limit

Kahan sey liya hai yeh
Sir konse code ka reference hai yeh

Please confirm me.
Sir, in which code is the condition you mentioned written?
Excellent, very good,good,fair etc

Sir mujhe strength ko laker bht fight krna pdta h... Mara jo problm h sir ...mara jo daily basis ka cube ka strength ata h usko lker.. Client bolta h ki standard deviation add krne ka bad.. Jo strength ayga.. Utna hi strength hona chahey.. But daily basis ka jo cube strength hota h book characteristics strength suppose M-30 grade h to uska 28 days ka strength 28 hona chahiye but... Clients usko fail bolta h... Plz advice sir ji
Revise your design and use water Cement ratio less and use Superplasticiser
Thanks sir ji
In which code mention standard deviation class.
According to Hemsworth
Sir according to IS 10262 -2019, higher value is used between assumed Standard deviation and value of x. But here you only use value of standard deviation. Plz explain sir and also explain acceptance criteria of concrete... Can we use acceptance criteria , that formula given in sec 903.1 or sec 1700-5 cl 1. Plz
This video was posted on 29th August 2018 , aimed to understand "how to determine the standard deviation of cube compressive strength. .Please do not club them for concrete mix design .Please see my video pertaining to concrete mix design as per IS 10262 -2019 .

Hum log standard deviations kyu karte hai concrete ka
Haam kaise cube ka strength bada sakte hey sir g abhi toh bahut thandi si mausam chal raha hey...
By maintaining the temperature of curing tank between 25*c to 29*c
Please yeh

Wali limit kahan sey li
Please code btao nah
According to Himsworth
Sir kindly confirm me that as per site cube test wich result will be accepted as a passing result characterstic strength or target mean strangth
Target Strength is used for designing concrete mix whereas characteristic strength is used for day to day work.

Already in description you can download from there
Sir ji please RE Wall par koi video
OK
is code konsa hai sir iska
According to Himsworth
Gsb grade 1 individual grading needed sir please
Please do on available aggregate
sir 2.8
2.8 to3.4
3.4 to4.1
4.1 to 4.8 kaha se ayay sir plz ans me sir muje mil ni raha plz sir
yeh question hai sir iska ans dena plz
sir apne iska answer nahi diya
According to Himsworth
Sir (x-x)2 kaise nikala
Please download the excel sheet
Sir where is mention the limit good very good fair ,poor
According to Himsworth
A.M=42.51 kya hai
kindly share with us excell sheet

42.51 kkaha se mila
Please see full video with interest
please use is 456
Unable to understand?
@@HIGHWAYGUIDE sir ji i mean to if i accept is 456 for acceptance criteria of cube then its worng or correct
@@er.sayanpal Correct
17 kya hi sir
N-1 , Where N is the number of sample
@@HIGHWAYGUIDE No of Sample 18?
Sir A.M = 42.51 samajh mein nahin aaya
AM means Arithmetic Mean
Sir yah aata hai kahan se
