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

The price comparison between UHPC and ordinary concrete should not be based solely on unit price, but on a comprehensive cost analysis over the full life cycle. Although the unit price of UHPC is 20-30 times that of ordinary concrete, the overall benefits brought by its superior performance may make the actual cost of use lower.

In a sea-crossing bridge maintenance project in Shenzhen, a detailed cost analysis showed: although the unit price of UHPC is 12,000 yuan/cubic meter, 30 times that of ordinary concrete (400 yuan/cubic meter), UHPC only requires a 50mm thickness, while ordinary concrete needs 300mm. Material consumption is reduced 6-fold, and transportation and construction costs decrease accordingly. More importantly, the UHPC maintenance cycle is expected to be 30 years, while ordinary concrete needs 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 yuan/cubic meter, but used in smaller quantities. Ordinary concrete: 400 yuan/cubic meter, but used in larger quantities. The difference in material consumption needs to be considered.

Construction Cost Comparison

UHPC construction requires specialized equipment and technology, resulting in high labor costs. However, construction is fast and the construction period is short. Ordinary concrete is simple to construct, but takes longer. Construction efficiency needs to be comprehensively evaluated.

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 annual average cost.

Maintenance Cost Differences

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

Indirect Benefit Considerations

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

It is recommended that major projects adopt full life-cycle cost analysis to select the solution with the optimal overall cost. Qinglong UHPC, with its long service life and low maintenance characteristics, has a clear advantage in terms of full life-cycle cost.
