[Solved] To make 1 cu.m of 1 : 2 : 4 concrete by volume, the coarse a? ›

The amount of coarse aggregate required to make 1 cubic meter of concrete for a given mix is 0.88 m³.

iii) Concrete ratio = 1 : 2 : 4, which implies for 1 cubic meter of concrete contains 1 part cement, 2 part sand or fine aggregates and 4 parts aggregates or coarse aggregates.

Volume of aggregate =1.54×47=0.88m3□8.85 m3.

Now, the standard weight of 1 bag of cement is 50 kg, and the density of cement is 1440 kg/cubic meter. =0.0347 cum. = 6.25 bags. So, you require 6.25 cement bags for your 1 cubic meter construction and remember, using this formula, you can also calculate the cement for other concrete mix design ratios.

A 1:2:4 mix is the ratio of 1 volume of cement powder, two volumes (think “buckets” or cubic feet”) of sand and four volumes of gravel. Water is then added (depending on the w/c ratio desired) sufficient to give the required slump.

If you know the length, width, and height of the space that you want to fill with concrete, then you can plug those measurements into a simple formula (length x width x height = volume) to get the precise quantity of concrete needed for a project.

Aggregate volume = (3/5.5) x 1.57 = 0.856m3

so these are the calculation to find out the quantity of material in M 20 grade of concrete for one cubic meter .

A basic mixture of mortar can be made using the volume proportions of 1 water : 2 cement : 3 sand. Most of the student activities can be conducted using this basic mixture. Another "old rule of thumb" for mixing concrete is 1 cement : 2 sand : 3 gravel by volume.

iii) Concrete ratio = 1 : 2 : 4, which implies for 1 cubic meter of concrete contains 1 part cement, 2 part sand or fine aggregates and 4 parts aggregates or coarse aggregates.

How many bags of concrete do I need for 1 cubic meter? ›

We know that 1 x 20kg bag of cement makes 0.01m³ of concrete, and that 100 x 20kg bags of cement make 1m³ of concrete.

Medium-strength concrete suitable for domestic floors, footpaths and driveways. To make 1 cubic metre of concrete, you will need: 7 bags cement + 0.70 cubic metres sand + 0.70 cubic metres stone.

1 Cubic Meter of Concrete

1m³ of concrete = 150l water + 250kg cement + 700kg sand + 1200kg aggregates.

1 Cubic Meter of Concrete

1m³ of concrete = 150l water + 250kg cement + 700kg sand + 1200kg aggregates.

To make 1 cubic metre of concrete, you will need: 7 bags cement + 0.70 cubic metres sand + 0.70 cubic metres stone. High-strength concrete suitable for precast concrete, heavy-duty floors. To make 1 cubic metre of concrete, you will need: 10 bags cement + 0.65 cubic metres sand + 0.65 cubic metres stone.

If you took metric measurements, then multiply the length by the width by the depth (L x W x D) to find the volume needed in cubic metres. For measurements in centimetres, multiple the measurements by 100 to find the amount in metres.

We generally recommend a 5 to 1 ratio with cement to produce good strong concrete. Cement is available by the bag and we stock 25kg or 40kg bags. You will need 6 x 40kg bags per cubic meter.
