The reasons of cube size 150×150x150mm 1. Smaller dimension cubes are easy in casting , curing & Testing . 2. For larger dimensions the loading capacity of testing equipment is also expected to be high i.e. Higher cost of Equipment. 3. And if testing loads are high safety required for people handling equipment are also high & Cube Weight high also..
Sir you explain very well thank you sir✌️✌️🙏🙏
Very nice sir ji . please upload more related video which is more helpful to us.
After long time a good video
Post daily good videos Bro
Very good explanation sir 😊😊
Very nice video sir 😊😊
Sir ek dout hai cube kasa lagta hai machine ( mtlb kis side pa load dalta hai
Love u Sir from Dubai
Nice update
Very good sir..
Fantastic sir
Pls suggest me CTMachine with good quality and accuracy in both way
nice one sir
Very very thanks sir
Maximum strength ka bhi koi criteria hota h kya kisi grade ke liye.
Actually mein target strength se 15 % Jada tak ja sakta hai but ye kahi Is code mein mention nahi hai dear.
@@rbsinghcivilengineeringaca6777 sir aggregate crushing value test m rate of loading per sec kitna hoga IS code m 40Tonne upto 10 min de rkha h.
@@ershahnawaz220 0.0011 ton per second hoga dear..

Sir hamara wala CTM digital nahi h dial wala h.
Kn m wahi ( 0.67kn/sec) value set karna hoga kya?
Sir isme pace rate range kitna hona chahiye@@rbsinghcivilengineeringaca6777
Respect sir
Nice video sir ji
Sir kahake ke ho aap
Great sir, M25 gives strength of 43N/mm2👍👍
Ji , because cement content - 380 kg & ultra tech OPC 53 Grade hai.. ush liye..

How to calculate load reat sir cube and block 400×200×200
Cube :
Size :- 150 x 150 x 150 mm
So that Compressive strength = load/ Area
Area :- Length x width
150 x 150 mm
22500 mm2
And load :- 610 KN
1kN :- 1000N
Calculation :- 610 x 1000/22500
27.11 N/mm2
Block size :- 400x200x200mm
Area :- 400x200
80000 mm2
Compressive strength :- Load/area
610 x 1000 /80000
7.625 N/mm2
Rate of load CTM machine ka dono ke liye equal hi rahe gaa..

Sir iss ke baad mein acceptance criteria as per IS CODE. Nahi kartey kya?
Mujhe thoda doubt hai kya email id mill sakta hai?
Jarur ,dear acceptance criteria per jald hi video aayega 👍👍
@@rbsinghcivilengineeringaca6777 great sir,
Cube validation test ( this vedio) and acceptance criteria test k liye seperate samples lene hogey?
Sir 🙏
Why we use cube size 15*15*15cm not 20*20*20cm or 10*10*10cm?
The reasons of cube size 150×150x150mm
1. Smaller dimension cubes are easy in casting , curing & Testing .
2. For larger dimensions the loading capacity of testing equipment is also expected to be high i.e. Higher cost of Equipment.
3. And if testing loads are high safety required for people handling equipment are also high & Cube Weight high also..
@@rbsinghcivilengineeringaca6777 thanks sir
Sir aap ka number mil jayega
Cube result 130 % se jyada nhi hona chaiye
