Concrete Mix Ratio (1:2:3:4)

1 Part Cement – Acts as the binding material.

2 Parts Sand – Fills gaps and improves workability.

3 Parts Gravel (Aggregate) – Provides strength and durability.

4 Parts Water – Hydrates the cement and allows mixing.

Water-Cement Ratio (W/C):
The amount of water should be controlled carefully. Too much water reduces concrete strength, while too little water makes mixing difficult.

Result:
A properly mixed concrete blend suitable for general construction works such as slabs, pavements, and foundations.

10-Storey Building Drainage & Sewerage System

🏢 A 10-storey building uses a vertical drainage system to collect wastewater from all floors and safely discharge it to the municipal sewer or septic tank.

🔹 Main Soil Stack (4" / 100 mm): Carries sewage from toilets (WC).

🔹 Waste Stack (3" / 75 mm): Carries wastewater from sinks, basins, showers, and bathtubs.

🔹 Vent Stack (2" / 50 mm): Provides airflow, prevents foul odors, and maintains proper pressure in pipes.

🔹 Horizontal Branch Pipes: Connect sanitary fixtures on each floor to the vertical stacks.

🔹 Building Drain: Main underground pipe that collects all wastewater and conveys it to an inspection chamber.

🔹 Inspection Chamber (IC): Allows inspection, cleaning, and maintenance of the drainage system.

🔹 Final Disposal: Wastewater flows to a septic tank or the public sewer network.

✅ Purpose: Safe wastewater disposal, odor control, proper ventilation, and easy maintenance of the plumbing system.
