# What is weight of Sand per cum ?

Dear Friends ,

You are surprised at this simple question ?

Sometimes such very earthly and common questions can also stump you out during the interview. You should not take such questions lightly .

What is the weight of one cubic meter of sand?

By the way do you know the answer ?.

By the way , do you know , how much ingredients need to be taken for the concrete ?

First you should see this video. This explain what is the meaning of the term grade and it also explains how to convert a grade into the proportion of materials :

Then you would like to see the calculations for finding out the materials for 1 cum of concrete :

How to find the Materials for concrete

If you know all this but are not aware as to what is meant by the grade of cement , then you must also see this video :

What is the grade of cement ?

# What is the maximum cement quantity for m25 grade concrete using admixture, considering all the other features?

Mix proportion for M25 grade of concrete is 1:1:2(cement:fine aggregates:coarse aggregates). So if you need 4cu.m of M25 concrete, we need to have 1cu.m of cement. So, theoretically, for 1cu.m of M25 concrete, we need to have 0.25cu.m 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.

So, for preparing 1cu.m of M25 concrete, quantity (dry volume) of cement required = 1.55 X 0.25 = 0.3875 cu.m
Now a bag of cement(50 kg) corresponds to 0.035cu.m of cement.
Hence 11 bags of cement are required for preparing 1cu.m of M25 concrete.

Admixtures(like plasticisers, super plasticisers) are usually added to increase workability of the mix at lower water cement ratio. So, I don’t think addition of admixture would change the quantity of cement.
