Size of brick with Mortar = 20 cm × 10 cm × 10 cm
No. of bricks required per 1 m3 brickwork = 1 / (0.2 × 0.1 × 0.1) = 500 nos.
No. of bricks for 10 m3 brickwork = 500 × 10 = 5000 nos.
Size of brick without Mortar = 19 cm × 9 cm × 9 cm
Actual volume of 5000 bricks = 5000 × (0.19 × 0.09 × 0.09) = 5000 × 0.001539 = 7.695 m3
approx 7.7 m3

We generally designate stirrups by its external dimensions. For example, a 250mm x 300mm stirrup has the 250mm and 300mm dimensions in perpendicular directions as shown in Fig 1.
Now a stirrup has 2 bends, types of which are shown in Fig 1 and Fig 4. Guideline of minimum bend length is as per Cl.3.8 of BIS2502 (shown in Fig 3).

On rebar pieces, different items are encrypted in the following manner:
Here, X = Dia of rebar in mm, eg, 20
ABCD = Brand of rebar, eg, TATA TISCON / SAIL / JSPL etc
Y = Yield stress of rebar, eg, 500 indicates Fe500 with yield stress=500 Mpa

There are a number of ways in which the superstructure can be built. In areas where average to good quality bricks are available, the walls of houses for two to three storeyed constructions can be built out of bricks with the slabs, lintels, chajja etc. in reinforced concrete. Such construction is supported entirely on load bearing brick walls (Fig 1), foundation of which ultimately transfers the building load to underneath soil.
