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...
16102016 0183 32 How to Calculate Cement, Sand and Aggregate Quantity in Concrete About This channel contains Technical Lectures on Civil Engineering from personal field experience SUBSCRIBE channel and HIT ....
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...
04112018 0183 32 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...
how do we calculate quantity of cement , sand and aggregates in 1 m3 of M30 grade concrete ?...
The formula for calculating the quantity of cement is, cement = dry volume of the concrete x cement ratio / sum of the ratio here, Dry volume of the concrete = wet volume of concrete x 154 the wet volume of concrete means volume of concrete af....
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...
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...
