At design for dry consistency concrete mixes mut be the consideration with deterioration on the regarding the voids. Certain student is researched on the regarding the relation the voids and the strength, other properties, however, we have not the saitable results on the some characters of freshly dry consistency concrete. Auther has found the similarity relation so "Constant Water Contents Low." By Inge Lyse, that is, "In the case the voids contents would be determine according to the water contents, per unit volum of concrete, not so consequence of mixes as ordinary concrete." This result can be shown by the following approximate ellipticall equation, [numerical formula] The compressive strength would be the determain by the function of cement tatal porosity (C/W+V). This proposal is based upon the formula regarding the relation is mentioned. Where, W; water content per unit volum V; void ratio per unit volum φ; porosity of none water concrete per unit volum C; cement content of absolute volum
