How do you calculate the quantity of aggregate in concrete?

The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg. Weight of coarse aggregate = 3 x 364.5 = 1093.5 kg.

### What is the ratio for m25 grade concrete?

How do you make a M25 concrete?

MIX RATIO BY VOLUME FOR ONE BAG OF CEMENT

1. Cement = One bag = 50 kg = 35 lit = 35000 cc.
2. Sand (room dry) = 2.14 x 35 = 74.9 lit = 74900 cc.
3. 20 mm Aggregate (room dry) = 3.63 x 35 = 127.05 lit = 127050 cc.
4. Free Water = 24.5 lit.
5. Normal Superplasticizer = 350 ml.

## How do you calculate M25 water cement ratio?

For M25 concrete they are mixed in the ratio of 1:1:2 (1 part cement to 1 parts sand & 2 parts aggregate by volume) to gain 25 MPa strength of concrete and water should be added in the range of 50% of weight of cement in moderate exposure condition for M25 concrete.

How do I calculate building quantities?

To calculate the quantities of materials, you need to multiply the total centre line length with breadth and depth of the construction. The centre line length will be reduced by half of breadth of every junction where the main wall is joined with the cross walls, partitions or verandah.

### How do you calculate M25 of concrete?

How do I calculate how much M25 concrete I need?

AGGREGATE

1. Quantity of Aggregate in Cubic Meter. Cubic Meter = DRY Volume of Concrete x ( Ratio of Aggregate / Sum of Total Ratio) = 1.54 x (2/4)
2. Quantity of Aggregate in KG. KG = DRY Volume of Concrete x (Ratio of Aggregate / Sum of Total Ratio) x Density of Aggregate.
3. Quantity of Aggregate in Cubic Feet.
