Some of the common type of bricks, depending upon the places of use, are shown in Fig. 2.13.
Round ended and bull nosed bricks (Fig. 2.13 (a, f)) are used to construct open drains. For door
and window jambs, cant brick, also called splay brick, shown in Fig. 2.13 (b, c), are most
suitable. The double cant brick shown in Fig. 2.13 (c) is used for octagonal pillars. Cornice brick
shown in Fig. 2.13 (d) is used from architectural point of view. Figure 2.13 (e) shows a compass
brick—tapering in both directions along its length—used to construct furnaces. Perforated
brick (Fig. 2.13 (g)) is well burned brick, but is not sound proof. Figure 2.13 (h) shows hollow
bricks. These are about l/3rd the weight of normal bricks and are sound and heat proof, but are
not suitable where concentrated loads are expected. Top most bricks course of parapets is
made with coping bricks shown in Fig. 2.13 (i). These drain off the water from the parapets.
Brick shown in Fig. 2.13 (j) is used at plinth level and for door and window jambs. Split bricks
are shown in Fig. 2.13 (k, 1). When the brick is cut along the length, it is called queen closer and
when cut at one end by half header and half stretcher, it is known as king closer.
