Please watch our video of "consistency test of cement"

Pace rate= Total Load/Time = 400 kN/10 minutes = 400 kN/600 seconds = 0.67 kN/second.

@@concrete-engineers thankyou sir

Mix design par detail video jald h upload kar denge.

Crushed sand ka specific gravity is video me diye gaye procedure si h karna hai, Silt content ka video next month tak upload ho jayega.

Noted

Bansakte ho

Thank you

For slump value more than 210 mm, flow test is recommended.

Glad you liked it!

Initial aur final setting time test isliye karte hain taaki cement ki setting characteristics evaluate ki ja sake. Initial setting time batata hai ki cement kitni der tak workable rahega, yani mixing aur placing ke liye available hoga. IS code ke according, ordinary Portland cement (OPC) ka initial setting time kam se kam 30 minutes hona chahiye. Final setting time batata hai ki cement kab fully set ho jayega, yani structure ko load bear karne layak bana dega. OPC ka final setting time zyada se zyada 600 minutes hona chahiye.

Cement third party NABL accredited laboratory si test karlijiye, setting time aur compressive strength. Slab dhalai ki liye OPC cement use karlijiye .

Thank you

Standard formula hai. IS 4031

Compressive strength test kar lijiye. Channel par video dekh lo.

There is no limit for these test.

Try it

Nice question. Truck me material loosely fill Kiya jata hai, loader si. Lekin truck destination par pahune tak vibration Hote hai jisse material compact ho jata hai.

@@concrete-engineers Sir main isase kya samjhaun ki truck mein material compact material hota hai to fir ek truck ka volume nikaalne ke liye truck ke material ki density compact density hi manlon FIR mein and cement ki 1440 kg prati metre cube density loose density hoti hai ya compact density hoti hai ya FIR tapped density in teenon mein se kaun si density Hoti hai jiska answer 1440 prati metre cube aata hai

Loose density hote hai

@@concrete-engineers loose density cement ki hai ya truck ke material ki

Cement ki density ki alag test hai, jald upload kar denge. Aggregate jo h brass me purchase kiya jata h , jo ki volumetric measurement hai, isliye density find karna important hota hai, jab ki cement metric ton me purchase hota hai.

3.15

25% si start karna hai, alag alag % ki sath trials lene hai dost.

Silica sand

Thanks

Thanks 🙂

Thank you

There is no upper or lower limits given in standards, but still consistency ranges from 25% to 35%.

Soon

Thanks a lot 😊

Soon

Strength kam hoge

I will make soon

jyada paani se cement ki strength kam ho sakti hai.

Will do soon

Thanks
