Foam concrete mix design calculator.
There is at present no guidance or standard method for proportioning foamed concrete because the hardened density of foamed concrete depends on the saturation level in its pores.
Fine aggregates 800 94 kg m 3.
The water cement ratio can typically vary from 40 80 and the foam content is commonly as high as 80 depending on desired density.

It will satisfy durability economy.
If you wish to calculate yield or trial batches please fill in the actual density and trial batch size ft3 cells.
For achieving pre formed foam concrete of design density mainly.
Proportional mix design foamed concrete are also discussed.
In this case standard deviation is taken from is 456 against m 20 is 4 0.
With the aim of obtaining the accurate measurement of any construction site the usage of this user friendly concrete mix design spreadsheet is absolutely necessary.
As in normal concretes the greater the air content the weaker the material so with foamed concrete densities ranging from 200kg m3 to 1900kg m3 it is not surprising that the lower densities produce the lower strengths and at present even the densities at the upper limits do not produce strengths much above 15n mm2.
Sample mix proportions of foamed concrete are given in table 1 2 3.
It will help you save time and hassle when creating mix designs and doing cost scenario analysis.
Astm c 796 97 provides a method of calculation of foam.
