Circular column concrete formwork calculation: price and turnover

Plastic concrete formwork has become a preferred choice for circular concrete column formwork construction due to its light weight, smooth finish, and environmental friendliness. Accurate calculation of its price and reuse cycle is crucial for cost control in construction projects.

Key Parameters for Calculation

First, define core variables: unit price of formwork (USD/set), effective area per set (m²), total project column area (m²), reuse cycle (times), and maintenance cost per cycle (USD/m²). Typical circular plastic formwork specifications for circular columns range from Φ300mm to Φ450mm, with a standard panel height 750mm

Reuse Cycle Determination

The reuse cycle of plastic formwork depends on material quality, handling, and maintenance. while reinforced polypropylene (PP) variants can reach 80-120 times. Factors affecting reuse include:

1. Proper demolding (avoiding brute force removal)

2. Regular cleaning and rust prevention treatment

3. Storage in dry, shaded environments

4. Load-bearing capacity during installation (not exceeding design limits)

Cost Optimization Insights

Comparing with steel formwork (reuse 200+ times but P 3x higher) and plywood (reuse 5-8 times), circular plastic formwork strikes a balance between cost and durability for mid-to-large projects.

In conclusion, precise calculation of plastic formwork’s price and reuse cycle requires integrating material properties, project scale, and maintenance practices. By optimizing these factors, construction teams can achieve significant cost savings while ensuring construction quality.
