The farther apart the supports the less the pressure necessary to break the brick, and the greater the cross section, the greater the pressure necessary. Since this is so, it is necessary that for purposes of comparison all results of the breaking strength be reduced to some uniform expression, which shall take account of the differences in length, width and thickness of the brick. The most accurate expression is that termed the modulus of rupture, which is calculated from the following formula: 2 b h in which R = Modulus of Rupture. W = Pressure necessary to break the brick. 1 = Distance between the supporting knife-edges. b = Breadth of the brick. h = Thickness of the brick. That is, three times the pressure in pounds multiplied by the distance between the supports is divided by twice the breadth of the brick, multiplied by the square of the thickness. If the pressure necessary to break a brick was 2,000 pounds, distance between supports 6 inches, width of brick 4 inches, and thickness 2 inches, the modulus of rupture would be calculated as follows: --- 2-= 1125 pounds. Absorption tests.--An absorption test is made for determining how much water a brick is capable of absorbing. This indicates the degree of porosity which it possesses. Vitrified brick which are impervious, or nearly so, will absorb little or no water. Many common brick may absorb an amount of water equal to 15 per cent., or even 20 per cent. of their dry weight. It is easily understood that if a brick of high porosity is exposed to a freezing temperature when its pores are filled with water, the expansion of the latter, when changing to ice, may be sufficient to disrupt the brick, either after one freezing, or after rep.
