how do we calculate quantity of cement , sand and aggregates in 1 m3 of M30 grade concrete ?...

Concrete Mix Design As Per Indian Standard Code From the quantities of water and cement per unit volume of concrete and the percentage of sand already determined in steps 6 and 7 above, calculate the content of coarse and fine aggregates per unit volume of concrete from the following relations:...

04112018· So if you need 4cum of M25 concrete, we need to have 1cum of cement So, theoretically, for 1cum of M25 concrete, we need to have 025cum of cement But in practice, whenever we estimate quantity of cement for concrete or mortar, we consider 50-55% extra quantity This extra quantity is for voids, wastage, etc...

M25 mix has a ratio of 1 cement to 1 sand and 2 stone jellyie 1:1:2 This means cement volume is half of stone jelly volumeTo prepare 1cum of concrete we need 00 cum of jelly So we need 09/2= 045 cum of sand So weight of cement required = 045x1440 =648 kg of cementapproximately 13 bags...

But in practice, whenever we estimate quantity of cement for concrete or mortar, we consider 50-55% extra quantity This extra quantity is for voids, wastage, etc So, for preparing 1cum of M25 concrete, quantity (dry volume) of cement required = 155 X 025 = 03875 cum Now a bag of cement(50 kg) corresponds to 0035cum of cement...

A simple yet more accurate method (DLBD method) of calculating cement, sand and aggregate for Nominal Concrete mix M15, M20, M25 and M30 grade Concrete...

As, the quantity of concrete required for large constructions are huge, economy in quantity of materials such as cement makes the project construction economical Concrete Mix design of M20, M25, M30 and higher grade of concrete can be calculated from example below...
