How to convert 1cu ft. of sand & coarse aggregates into kilogram?/ Calculating the weight of sand & aggregates per cu ft.

 The weight of the building materials/ cu ft. depends upon the density of that particular material.

1. Coarse aggregates:



The density of coarse aggregates used in the construction works mostly varies from 1550kg/cum. to 1850kg/cum.

Let us consider the average density of 1700kg/cum. for the calculation purpose.

As you know, 1 cum = 35.3147 cu ft.

and 1cum of aggregate weighs 1700kg.

So, 35.3147 cu ft. = 1700kg.

      1 cu ft.          = -------?

By cross multiplication,

The weight of 1 cu ft. of coarse aggregate 

= [1700kg.÷ 35.3147]

= 48.14 kg.


2.  Sand:




The density of sand used in the construction works mostly varies from 1450kg/cum. to 1800kg/cum.

Let us consider the average density of 1625kg/cum. for the calculation purpose.

As you know, 1 cum = 35.3147 cu ft.

and 1cum of sand weighs 1625kg.

So, 35.3147 cu ft. = 1625kg.

    1 cu ft.          = -------?

The weight of 1 cu ft. of sand

= [1625kg.÷ 35.3147]

= 46.01 kg.


Note:

What are the factors that affect the density of sand?

The density of sand depends upon

1. Type of sand material: If the sand particles are formed of heavier materials, the density of such sand is more.

2. Presence of water: Dry sand has less density & moist sand carries more density due to the presence of water in its voids.

3. Voids in the sand: Loosely filled sand weighs less when compared to packed sand.

So, to find the accurate weight/ cu ft., the best method is to find the density of sand & aggregates used in the construction works.
