of cement in young concretes. For high strength concretes, increasing cement content beyond a certain value, of the order of 550 kg/m3 or so, may not increase the compressive strength . From these considerations as well as those of overall economy, the maximum cement content in the concrete mixes was limited to 530 kg/m3 for prestressed concrete

28/09/2016· Finally, C = 336.14 Kg / m 3 of concrete. But from table 5 of IS456-2000, Minimum cement content required for moderate exposure condition for M15 grade concrete is = 240 Kg/m 3 of concrete. Greater of above two values will be the cement content. Hence, C = 336.14Kg.

18/02/2020· Ratio of water and cement is known as water cement ratio which is about 45 litre per bag cement for m10 grade of concrete. 1 bag cement required = 45 litre of water. 51 bags = 51×45= 2295 litre of water. So we have required water consumption in pcc 1:4:8 is approx 2295 litre of water for 100m2 having 150 mm thick slab.

The cement content of concrete is important from the aspect of durability, impermeability and strength. Too low a cement content may cause inadequate structural capability or more frequently may not provide a durable protective environment for the steel reinforcement, permitting rapid carbonation and subsequent loss of the protective alkaline environment for the steel. Too high a cement content may …
