- Q:20 concrete stairs step by step how much money
- Fourth, the concrete template project engineering calculation example 1, as shown in the figure, seeking 100 pieces of prestressed reinforced concrete hollow plate template project volume. Solution: Engineering amount = 3.28 × [(0.57 0.59) × 0.12 ÷ 2 - π / 4 × 0.0762 × 6] × 100 = 0.139 × 100 = 13.9m3 2.
