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
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
