Hello friends. This is Mukesh from Learning Civil Technology. Aj ke post mein main apko bataunga How to calculate M25 Grade Concrete Cement Sand Aggregate Water Quantity at Construction Site. Is post ki ek khas baat ye hain ki mai apko material ka calculation different unit me bataunga. Jaise ki Cement ka Weight main apko Cubic meter, KG, Bags aur Cubic feet me nikalna sikhaunga. Waise hi Sand ka main apko Cubic meter, KG, Bags aur Cubic feet me nikalna sikhaunga. Isi tarah Aggregate ka bhi bataunga apko.
Mujhe pata hain ap log sab iske liye bahut excited ho. To chaliye copy pen le ke baith jaiye aur ha ek request hain. Agar ye post apko pasand aye to ise jarur apne Civil Engineer dost aur Juniors tak jarur pahuchaye. Kiu ki kuch responsibility apki bhi hain is Nation ko aage badhane mein.
To chaliye post ki taraf aage badhte hain.
Cement, Sand, Aggregate aur Water ki quantity nikalne ke liye maine yaha Concrete ka Volume considered kiya hain 1 Cubic Meter. Agar apko 1 se jada Cubic Meter ke liye material nikalna hain to simply apko 1 Cubic Meterme jitna material apko lag raha hain, use apke Concrete ke Volume se multiply kar dena hoga. Apko apke material ka weight mil jayega.
Toh Cement, Sand, Aggregate and Water ki Quantity ko nikalne ke liye hame kuch data chahiye. Wo hum assume kar lete hain apne hisab se.
Volume of Concrete considered – 1 Cubic Meter
[NOTE : Yaad rakhiyega ye 1 Cubic Meter hamara WET Volume hain. Material calculation ke dauran hame ise DRY Volume me convert karna hoga. Wo hum apko aage batayenge]
Grade of Concrete Mix – M25
[NOTE : M25 Grade ka Concrete banane ke liye material ka ratio hota hain (1:1:2). Yaha pe 1 denote karta hain ‘Part of Cement’, 1 denote karta hain ‘Part of Sand’, aur 2 denote karta hain ‘Part of Aggregate’]
Water ki Quantity nikalne ke liye hame lagega Water – Cement Ratio. Toh hum yaha Water – Cement Ratio ko consider kar lete hain 0.45
Top chaliye main apko Cement, Sand, Aggregate aur Water ki Quantity ko nikalna batata hu.
Sab se pehle hum, M25 Grade Concrete ka jo Ratio hain uska summation nikal ke rakh lete hain.
Sum of Ratio of Cement , Sand and Aggregate = 1+1+2 = 4
Ab hame Concrete ke WET Volume ko Dry Volume me convert karna hoga. Iske liye hame Dry volume ko 54 percent increase kar dena hoga. Ab ap poochenge ki 54 percent hi kiu increase karenge. Toh main apko bata du ye 54 percent ek experimental data hain, jo hame experiment ke jariye mila hain. Toh chaliye assumed concrete ko WET se DRY volume mein convert kar lete hain.
Maine upar WET Concrete Volume consider kiya tha 1 Cubic Meter. Toh DRY Volume hamara ho jayega,
DRY Volume = WET volume + (54 % of WET volume)
DRY Volume = 1 + (54 x 1/100) = 1.54 Cubic meter
Toh isi DRY Volume (1.54 Cubic Meter) me hum nikalenge Cement, Sand, Aggregate aur Water ki Quantity ko. To chaliye suru karte hain. Umid karta hu yaha tak apko sab samajh me aya hoga.
Water ki Quantity nikalne ke liye hame Water/Cement Ratio chahiye, jo maine consider kiya hain 0.45 aur Cement ki Quantity ka bhi pata hona jaruri hain.
Cement ki Quantity hamne av av nikala hain. Cement ki Quantity hain 554.4 KG
Ab niche diye hue formula se hum asani se WATER ki quantity nikal sakte hain. Dhayan dijiye.
Water / Cement = 0.45
Or, Water = 0.45 x Cement
Or, Water = 0.45 x 554.4
Or, Water = 249.48 KG or Equivalent to 249.5 Litre.
Toh is tarike se hum asani se Cement, Sand, Aggregate and Water Quantity in Concrete at Construction Site nikal sakte hain.
