Maturity Method for Strength Prediction
Temperature and Strength Monitoring of Concrete
FPrimeC Solutions offers cost-effective, and easy to implement solutions for predicting the early age strength of concrete using the Maturity Method. We utilize the most innovative wireless sensors for a Maturity Measurement that eliminates wire connection, and expensive data loggers. Built on a wireless connectivity concept, our solutions reduce trip hazards, and saves you time in measuring temperature variation inside concrete.
Our testing methodology is in accordance with the standard procedure described in the ASTM C 1074; and is approved by ACI 318 and CSA A23.3 codes for the purpose of strength measurement. Wireless temperature measurement sensors are embedded inside your concrete pour, and transfer temperature data right to your wireless tablet or mobile phone.

How We Implement Maturity Testing in Your Project
Step 1 - Establish Maturity and Strength Relationship
The first step is to establish the project-specific maturity and strength relationship. To do so, the standard procedure in the ASTM C 1074 is used. Concrete Samples will be tested for temperature variation (during curing phase), and compressive strength values at certain ages. The maturity index for each age is calculated by calculating the area under temperature variation curve. A logarithmic function is then calibrated for the relationship between maturity index and concrete strength.
Step 2 - Measure and Record Temperature in Field
The temperature of concrete will be recorded at 30 minute intervals; this information is used to measure the maturity index at any given time.
Step 3 - Estimate Concrete Strength
The maturity index calculated in Step 2, will be given to the strength-maturity function that was developed in Step 1. The function returns the estimated value for concrete strength! As simple as that.
