THE STRENGTH OF CONCRETE. 179 K = 1,965, if the strength is in kg. per sq. cm.; or K = 28,000, if the strength is in lbs. per sq. in. This particular value is applicable only to the cement used by Mr. Feret in his experiments and to specimens at the age of five months, but the principles involved… … 0.3000 0.1000 0.2000 ABSCISSAS ( -j^) 2 Fig. i. Derivation of Feret's Formula for Strength. -(Bulletin de la Societe a" Encouragement pour Vlndustrie Nationale, 1897.) The most practical application of this formula is in the determination of the relative compressive strengths of various mortars…
