= the uniaxial compressive strength of foamed concrete; = porosity; = gel-space ratio; = the air/cement ratio; = casting density; = the specific gravity of cement; = unit weight of water; = water-solid ratio by weight; = uniaxial compressive strength of concrete at a porosity of 0; = filler-cement ratio by weight; = admixture-cement ratio by volume; = gel strength; = hydration water-cement ratio by weight; = volume of cement; = filler volume of unit volume; = fresh density; = empirical constant. |
