Calculation Of Materials For Plastering

Here, we will be calculating the quantities of materials i.e., cement and sand, required for plastering. We will take 100 sq. metre area of wall and calculate accordingly. Moreover, some extra percentages are taken on volume for other construction works during the process.

Assuming thickness of plastering,
Inside = 12 mm
Outside = 20 mm
Ceiling = 6 mm

Mortar Calculation in Brickwork

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

Cutting Length of Stirrups

By
Sourav Dutta
Manager-Civil

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).

Brand embossing
On rebar pieces, different items are encrypted in the following manner:

Brand embossing

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
