In this video you’ll learn:
Material fundamentals: 50 kg cement bag, 1440 kg/m³ density, brick strength and quantity per m³
Concrete mix basics: what M20 means and the 1:1.5:3 mix ratio
Key dimensions: minimum slab thickness, DPC thickness, and comfortable stair riser and tread sizes
Steel reinforcement: development length, bar spacing (c/c), steel bar weight formula (d²/162), and when to use couplers instead of lapping
Site best practice: maximum 1.5 m concrete free‑fall to avoid segregation
If you’re a civil engineering student, fresh engineer, or site supervisor who wants to strengthen core construction basics, this video is for you. Watch till the end and comment which rule you see ignored most often on real projects.
