cMatriX
Concrete strength in real time
Only for iPhone
Free
iPhone
cMatriX monitors concrete curing on site and tells you when your concrete is strong enough — to strip formwork, load a slab or continue work.
Connect a cMatriX sensor via Bluetooth, and the app reads the temperature log and calculates concrete maturity (Sadgrove method) and compressive strength (Eurocode 2). You see the current strength in MPa, progress toward your target and a forecast of when it will be reached.
No sensor yet? Enter temperatures manually for an estimate.
• Real-time strength in MPa and % of target
• Strength curve and temperature chart
• Formwork stripping estimate
• Outdoor temperature and frost warnings for your site
• Mix recipes with lab calibration
• PDF reports for documentation
• Works offline; your data stays on your phone
The cMatriX sensor has its own display, so the reading is available even on sites where phones are not allowed.
