How Does UHPC Price Compare with Ordinary Concrete? Qinglong UHPC Full Life-Cycle Cost Analysis

The price comparison between UHPC and ordinary concrete cannot rely solely on unit price; a comprehensive cost analysis should be based on the whole life cycle. Although UHPC's unit price is 20-30 times that of ordinary concrete, the overall benefits brought by its outstanding performance can make the actual cost of use lower.

In a maintenance project for a sea-crossing bridge in Shenzhen, a detailed cost analysis showed: although UHPC's unit price is 12,000 RMB per cubic meter—30 times that of ordinary concrete (400 RMB per cubic meter)—UHPC only requires a thickness of 50mm, while ordinary concrete needs 300mm. Material usage is reduced by 6 times, and transportation and construction costs decrease accordingly. More importantly, the maintenance cycle for UHPC is expected to be 30 years, whereas ordinary concrete requires repairs again after only 5 years. Calculating the total cost over 50 years, the UHPC solution actually saves 40%.

Initial Investment Cost Analysis

UHPC: 12,000 RMB per cubic meter, but with low usage. Ordinary concrete: 400 RMB per cubic meter, but with high usage. The difference in material usage must be considered.

Construction Cost Comparison

UHPC construction requires specialized equipment and technology, resulting in higher labor costs. However, it offers fast construction speed and a shorter construction period. Ordinary concrete construction is simple but takes longer. Construction efficiency must be evaluated comprehensively.

Service Life Cost Analysis

UHPC has a design life of over 50 years, while ordinary concrete lasts 10-15 years. Calculated over a 50-year cycle, UHPC has a lower average annual cost.

Maintenance Cost Differences

UHPC is nearly maintenance-free, while ordinary concrete requires regular maintenance. The difference in maintenance costs significantly affects the whole life cycle cost.

Indirect Benefit Considerations

UHPC's fast construction speed reduces traffic impact. Its long service life reduces indirect losses caused by repairs. These indirect benefits should also be included in the cost analysis.

For major projects, it is recommended to adopt whole life cycle cost analysis and select the solution with the optimal overall cost. Qinglong UHPC, with its long life and low maintenance characteristics, has a clear advantage in whole life cycle cost.
