Foam Concrete Mix Design Calculator

The mix design weights and volumes will now be proportioned on the right side of the grid.

Foam concrete mix design calculator.

F target f ck 1 65 x s 25 1 65 x 4 0 31 6 n mm 2. It will help you save time and hassle when creating mix designs and doing cost scenario analysis. Himsworth constant for 5 risk factor is 1 65. If you wish to calculate yield or trial batches please fill in the actual density and trial batch size ft3 cells.

Fine aggregates 800 94 kg m 3. 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. Water 191 6 kg m 3. Mix design calculator download our free mix design calculator for cellular concrete.

For achieving pre formed foam concrete of design density mainly. Procedure for concrete mix design of m25 concrete step 1 determination of target strength. The water cement ratio can typically vary from 40 80 and the foam content is commonly as high as 80 depending on desired density. Concrete mix proportions for concrete trial mix 1.

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. A very basic cellular concrete mix design would consist simply of portland cement water and externally generated foam which is also referred to sometimes as preformed foam. It will satisfy durability economy. Where s standard deviation in n mm 2 4 as per table 1 of is 10262 2009.

For trial 1 of concrete in lab to check its properties. Coarse aggregate 1087 75 kg m 3. Astm c 796 97 provides a method of calculation of foam. In this case standard deviation is taken from is 456 against m 20 is 4 0.

Sample mix proportions of foamed concrete are given in table 1 2 3. 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. Cement 383 2 kg m 3.
