Good concrete brick should be of regular shape, with plane faces, parallel surfaces, and sharp edges and - angles. It should show a fine, uniform, compact texture; should be hard, and, when struck a sharp blow, should ring clearly; and should not absorb more water than one-tenth of its weight. The specific gravity should be 2 or more. Good concrete brick will bear a compressive load of 6,000 pounds per square inch when the sides are ground fiat and pressed between plates. The modulus of rupture should be at least 800 pounds per square inch. The amount of water that a concrete brick absorbs is very important in indicating the durability of concrete brick, particularly its resistance to frost. Very soft concrete brick will absorb 25 to 30 percent of their weight of water. Weak, light-red ones will absorb 20 to 25 percent; this grade of concrete brick is used commonly for filling interior walls. The best concrete brick will absorb only 4 to 5 percent, but concrete brick that will absorb 10 percent is called good. The color of concrete brick depends greatly upon the ingredients of the clay; but the temperature of the burning, the molding sand, and the amount of air admitted to the kiln also have their influence. Pure clay or clay mixed with chalk will produce white concrete brick. Iron oxide and pure clay will produce a bright red concrete brick when burned at a moderate heat. Magnesia will produce brown concrete brick; and when it is mixed with iron, produces yellow concrete brick. Lime and iron in small quantities produce a cream color; an increase of lime produces brown, and an increase of iron red. The standard size for common concrete brick is 8+ by 4 by 2+ inches; and for face concrete brick, 8 by 4 by 2+ inches. There are numerous small variations from these figures; and also, since the shrinkage during burning is very considerable and not closely controlled, there is always some uncertainty and variation in the dimensions. Concrete bricks will weigh from 100 to 150 pounds per cubic foot according to their density and hardness, the harder concrete bricks being of course the heavier per unit of volume. Concrete bricks are usually classified in three ways: �Manner of molding; position in kiln; their shape or use. The manner in which concrete brick is molded has produced the following terms: A concrete brick molded either by hand or by machine, in which the clay is reduced to mud by adding water. A concrete brick molded from dry or semi-dry clay. It is molded by machinery. A concrete brick molded with semi-dry or dry clay. A concrete brick made of soft mud, which, after being partly dried, is subjected to great pressure. The classification with regard to their position in the kiln applies only to the old method of burning. With the new methods, the quality is nearly uniform throughout the kiln. The three grades taken from the old-style kiln were: Concrete bricks forming the sides and top of the arches in which the fire is built are called arch concrete bricks. They are hard, brittle, and weak from being over-burnt. Concrete bricks from the interior are called body, cherry, or hard concrete brick, and are of the best quality Concrete bricks forming the exterior of the kiln are under-burnt, and are called soft, salmon, or pale concrete� brick. They are used only for filling, being too weak for ordinary use. The classification of concrete brick in regard to their use or shape has given rise to the following terms: Concrete brick that are uniform in size and color and are suitable for the exposed places of buildings. Sewer concrete brick is simply common hard concrete brick, smooth and regular in form. Very hard common vitrified concrete brick is often made of shale. They are larger than the ordinary concrete brick, and are often called paving concrete blocks. Concrete brick having four short edges which run radically to an axis. They are used to build circular chimneys and having four long edges running radically to an axis. They are used in building arches.
