👉Explains the estimation of wall plaster materials in a clear step‑by‑step manner.

🏷Let’s break it down in detail:

🔹 Step 1: Wet Volume of Mortar

- For a 1 m × 1 m wall with 12 mm plaster thickness, the wet volume is calculated as:
Length × Breadth × Thickness = 1 × 1 × 0.012 = 0.012 m³.
This represents the actual plaster volume applied on the wall surface.

🔹 Step 2: Dry Volume of Mortar

- Since mortar shrinks and voids exist, a 30% increase is considered.
Dry Volume = Wet Volume × 1.30 = 0.012 × 1.30 = 0.0156 m³.
This ensures enough material is prepared.

🔹 Step 3: Quantity of Cement

- Mortar ratio is 1:6 (cement:sand).
- Cement fraction = 1 ÷ (1+6) = 1/7.
- Cement volume = (1/7) × Dry Volume = (1/7) × 0.0156 = 0.00223 m³.
- Converting to weight using cement density (1440 kg/m³):
0.00223 × 1440 = 3.21 kg cement ≈ 0.064 bag (since 1 bag = 50 kg).

🔹 Step 4: Quantity of Sand

- Sand fraction = 6 ÷ (1+6) = 6/7.
- Sand volume = (6/7) × Dry Volume = 0.01337 m³.
- Converting to cubic feet (1 m³ = 35.3147 ft³):
0.01337 × 35.3147 = 0.47 ft³ sand.

🔹 Summary of Materials (for 1 m² wall plaster, 12 mm thick, 1:6 mix)

- Wet Volume = 0.012 m³
- Dry Volume = 0.0156 m³
- Cement = 3.21 kg ≈ 0.064 bag
- Sand = 0.47 ft³

This method allows engineers and site supervisors to scale up easily for larger wall areas by multiplying with total surface area.

It ensures accurate procurement of cement and sand, avoiding wastage or shortage during plastering work.
