But sir as per IS cube should not be dry until they tested if they become dry then we have to give them curing for 24 hrs and then we can take test in wet conditions
Yes dear , lakin Maine aapko bataya h k cube ko surface dry karna h 30 min k liye. Iska matlab ye h k cube ki surface ka water sookh jaye , taaki cube ka weight sahi aaye . Ye bhi IS 516 ka provision h . Or aap jis case ki baat kar rhe h usme bhi agar aap 24 hrs k liye curing karenge to bhi test karne se pehle cube ko surface dry karna hoga. Thank you
Dear , Fill the mould in 3 layers. You are right tamping shall be 35 times. But it is 35 times for a 150 mm size cube. In the case of 100 mm cube tamping shall be 25 times.
@@valleytoridge9821 according is code 516-1959 The concrete shall be filled into the mould in Layers approximately 5 cm deep. And for cubical specimen 35 stokes for 15 cm cubes and 25 stokes per each layer for 10 cm cubes. And for cylindrical specimen the stokes shall not be less than 30 stokes per layer. There is not mentioned directly to fill in 3 layer or Four Layer .
Dear ! Agar aapko dekhna h k koi value kisi dusre value ka kitna percent h ....to simply aapko first value x 100/ second value kar dena h....for example agar aapke paas 200 Rs. H or aapke friend k pass 600 Rs. H ......or aapko dekhne h k (1) aapke pass aapke friend ka kitna percent h ....to ye ho jayega 200 x 100/600 = 33.33% ....yani ki aapke pass aapke friend k comparison me 33.32% Paisa h.....vahi pe agar aapko dekhna h k aapke comparison me aapke dost k pass kitna paisa h to ye hoga 600x100/200= 300% ...yani ki aapke comparison me aapke dost k pass 300 % Paisa h....jisko compair kiya jata h ...vo numerator me aata h ...or jisse compair kiya jata h vo denominator me aata h fir multiple by 100 percent me convert karne k liye aata h.... ...yha pe ek question or aa sakta h k aapke dost k pass aapse kitne percent Paisa jyada h .....to us case me aap karenge ...k dost k pass kitna paisa jyada h divide by karenge aapke pass kitna paisa h ....kyuki compair aapse kiya ja rha h ... multiple by 100....isliye ye ho jayega (600-200)x100/200 solve karne pe ye aayega 200% yani ki aapke dost k pass aapse 200% paisa jyada h....thik h.... Vhi pe agar aapko ye dekhna h k aapke pass aapke dost se kitne percent Paisa Kam h ...to aap isko karenge (600-200) x 100/ 600= 66.67% yani ki aapke pass aapke dost se 66.67% Paisa Kam h..... Is lecture me bhi humne yhi Kiya tha ...k kisi sample ki strength average se kitna percent jyada ya Kam h ...to vha pe humne kiya tha ( Average strength- sample ki strength)x100/ Average strength...
Great sir
Your videos are really easy to understand nd helpful sir ....plzzz ese hi ap video bnate rahiye ..
Great 👍🏼

Fill the mould in 4 layer with 35 tamping

Sir plz more lecture plz aap bahut achha padhte hai
I know editing mai. Bahut time lagata hai 😢
What is the utility of weight of cubes.
By the weight of the cube we can find out the density of concrete. The higher value of weight gives higher density. And high density means stronger.
Percentage kese nikalte hai

Cube ke liye per liyar 35 tamping karna hai sahi se padh lijiyega
Yes dear , 100 mm size cube k liye 25 times or 150 mm cube h to 35 times Tamping karna h
