PART C - MORTAR JOINTS
The strength of any brick structure depends on-
The strength of the brick.
The strength and elasticity of the mortar.
The workmanship of the bricklayer.
The uniformity of the bricks.
The method of laying the bricks.
The strength of mortar is normally greater than that of the brick. The strongest element of a brick wall is
mortar. Therefore, the way in which you lay bricks in mortar is very important.
3-4. Using a Trowel. To spread mortar for a bed joint, hold the trowel directly over the centerline of
the previous course, tilt the trowel slightly, and drop an equal amount of mortar on four or five bricks
along the wall unit (Figure 3-3). Do not make the row too long or the mortar will dry out.
Figure 3-3. Spreading mortar for the bed joint
3-5. Spreading and Furrowing. Use a trowel to spread the mortar about 1 inch thick for the bed joint,
and then make a shallow furrow (Figure 3-4).
