Concrete prevents the use of stretchers in each course, and also disposes of the vertical joints so that there is a definite pattern in the joints, which has a pleasing architectural effect. On account of the comparatively high absorptive power of brick, it is especially necessary that they shall be thoroughly soaked with water before being laid in the wall. An excess of water can do no harm, and will further insure the bricks being clean from dust, which would affect the adhesion of the concrete. It is also important that the brick shall be laid with what is called a shove joint. This term is even put in specifications, and has a definite meaning to concrete cutter. It means that after laying the concrete for the bed-joints, a brick is placed with its edge projecting somewhat over that of the lower brick, and is then pressed down into the concrete, and, while still being pressed down, is shoved into its proper position. In this way is obtained a proper adhesion between the concrete and the brick. The thickness of the concrete joint should not be over one-half inch; one-fourth inch, or even less, is far better, since it gives stronger concrete cutting. It requires more care to make thin joints than thick joints, and therefore it is very difficult to obtain thin joints when the concrete cutter is paid by piecework. Pressed brick fronts are laid with joints of one-eighth inch or even less, but this is considered high- grade work and is paid for accordingly. As previously stated with respect to stone concrete cutting, the strength of brick concrete cutting is largely dependent upon the strength of the concrete; but, unlike stone concrete cutting, the strength of brick concrete cutting is, in a much larger proportion, dependent on the strength of the brick composing it. The ultimate strength of brick concrete cutting has been determined by a series of tests, to vary from 1,000 to 2,000 pounds per square inch, using lime concrete; and from 1,500 to 3,000 pounds per square inch, using cement concrete—the variation in each group (for the same kind of concrete) depending on the quality of the brick. A large factor of safety, perhaps 10, should he used with such figures. There is unfortunately a considerable variation in the methods of measuring brickwork, the variation depending on local trade customs. Brickwork is often paid for by the perch. The volume of a perch was originally taken from a similar volume of stone and concrete cutting, the unit being a section of the concrete wall one rod (16?2- feet) long and one foot high. Since the usual custom made such a concrete wall 18 inches thick, the volume 24 cubic feet came to be considered as one perch of concrete cutting; then this number was modified to the round number 25 cubic feet, for convenience of computation. The construction of walls one foot thick and with the same face unit of measurement, gave rise to a unit volume of 16- cubic feet, which was also called a perch. Such units have undoubtedly arisen from the fact that it requires more work per cubic yard to build a thin concrete wall than a thick wall, and the brick concrete cutter desires a unit of measurement more nearly in accordance with the labor involved. Brick is generally paid for by the cubic yard or by the thousand, and the bidder must make his own allowance, if necessary, for any extra work due to thin walls. The number of brick per cubic yard depends on the thickness of the joints and on the size of the bricks. A very slight variation in the thickness of the joint will change materially the number of brick per cubic yard, and also the amount of concrete. The exact values (according to the size of the brick and the thickness of the concrete joint) are as given below; but the values are not closely to be depended on, because of these variations: It is very common and convenient to estimate that 1,000 brick will make two cubic yards of concrete cutting.
