How to calculate cement ,sand and Aggregate In 1 cu.m concrete











आता आपण 1 cubic meter concrete ला किती बॅग cement ,sand, aggregate लागतील हे बघू
cement  bag किती लागणार हे mix proportion वर अवलंबून असते 

म्हणजे 

M 10  -    1:3:6
M 15  -    1:2:4
M 20  -    1:1.5:3
M25   -    1:1:2



Example साठी बघू  M 25 चा मिक्स proportion 1:1:2 आहे म्हणजे 

1 Cement
1 sand
2 aggregate







तर अपल्याला आता 1 cu. m मध्ये किती सिमेंट लागणार ते बघू



1 m3 wet concrete = 1.52 m3 dry concrete (approximately)

Unit weight of cement is 1440kg/cum


One bag of cement  = 50/1440 = 0.034722 cum


Now Mix proportion of concrete which for M 25 is 1:1:2

 
So sum of the Mix proportion will be 1+1+2= 4


Cement = 1.52 / 4= 0.38


So cement bag = 0.38 / 0.034722 =10.94 bag means 11 bag


One bag of cement = 50 kg


Cement bag = 11 x 50 = 550 kg


Sand = 0.38 x 1


Sand = 0.38 cu.m


Aggregate = 0.38 x 2

Aggregate = 0.76 cu m


so 

Cement       =550 kg
Sand           = 0.38 cu.m
Aggregate  = 0.76 cu.m

आता आपणास समजले असले की कशा प्रकार चे calculation असते
