iPhone
Designed natively for iPhone and iPad.
iPad
Optimised iPad layouts for lab and office use.
Features
Designed for researchers, structural engineers, and lab technicians working with ultra-high performance concrete.
Every constituent converted to volume. Aggregate fills the remainder — guaranteed to sum to 1000 L/m³.
Define specific gravities, absorption values, and fiber types. Build multiple libraries per project.
Set casting dates, pin mixes to Home, and track progress toward the 28-day milestone.
One-tap professional reports with proportions, batch quantities, and volume balance.
Add steel, PP, basalt, PVA, or glass fibers with individual vol% and specific gravities.
Native SwiftUI. Optimised for both screen sizes. iOS 17+ with dark mode support.
The Method
UHP.x implements the Absolute Volume Method from first principles. Every constituent is volume-balanced.
UHP.x is a research-grade calculation aid. All mix proportions must be independently validated by a qualified engineer before field or structural application. The developer accepts no liability for any outcome arising from use of this application.
