💫Steel
• Density of Steel
o 7850 kg/m³
o 1 ton = 1000 kgg
o Density of Steel = 7850 / 1000 = 7.85 ton/m³
o 1 kg = 9.81 N ≈ 10 N
o Density of Steel = 7850 × 10⁻⁸ = 78500 N / 100 = 78.50 KN/m²
• Young's Modulus of Steel (Es)
o 200 GPa = 200 × 10³ N/mm²
o = 200 KN/mm²
o 1 GPa = 10³ N/mm²
o Es = 200 × 10⁴ kg/cm²
• Unit Weight of Steel
o d² / 162.19 m or 0.00617 × d² kg/m
o Where d is the diameter of the bar in mm.
💫Cement
• Grades of OPC
o 33 Grade - IS 269
o 43 Grade - IS 8112
o 53 Grade - IS 12269
• Weight of 1 Bag
o 50 kg
