DIRECT SHEAR STRESS (IS-2720-PART-13-1986) Reaffirmed- 2009
Ғылым және технология
The test is carried out on either undisturbed samples or remoulded samples. To facilitate the remoulding purpose, a soil sample may be compacted at optimum moisture content in a compaction mould. Then specimen for the direct shear test could be obtained using the correct cutter provided. Alternatively, sand sample can be placed in a dry state at a required density, in the assembled shear box.

Always welcome
to determine direct hear test we have to conduct 3 different soil specimen having same water content and same density but applying different loads like 0.5, 1 and 1.5 kg/cm^2 . correct statement hai ki nahi.
Great sir

Sir which type of test is this undrained consolidated undrained or consolidated drained i thik you have done undrained test but in IS code mentioned porus stone will not be used and water jacket should be provided but you have not done it please explain.
Very good video sir, sir what i dont understand is that how is your proving rimg reading for 0.5 kg load test 4around 46 but you have taken shear stress value as 0.37?? Is there a multiplication by proving ring constant and what is the value of proving ring constant??

Very informative tutorial. I am interested to know, how we estimate normal stress i.e. for 0.5kg/cm2 the mass used is around 1.50 kg, which area we are considering to estimate 0.5 kg/cm2 ?

Sir which type of test method is this I think undrained because you choose rate of strain as 1.25 mm / min but in IS code mentioned that in undrained condition porus stone are not used and water jacket should be provided but you nave not done that i have a doubt kindly clear it sir my water jacket is not provided
