Procedure and wireless system as the degree of setting and hardening of cementitious materials for predicting mechanical strength. # Wireless system as the degree of setting and hardening of cementitious materials comprises an ultrasonic sensor, a temperature sensor, sensor relative humidity, a wireless communication comprising at least two nodes for the acquisition and processing electronic signals from sensors and a computer system, such that the computer system calculates the mechanical strength of the cementitious material. Furthermore, the method comprises the following steps: capturing a temperature data T and humidity H, capture an ultrasonic signal for measuring propagation velocity V, capture an ultrasonic signal for measuring the reflection coefficient CR, send all earlier records of sensory signals to the master node, processing signals for the speed V and reflection coefficient CR parameters, send data to the computer system and calculate the minimum strength R {sub, C} (V, CR, T , H) of the cementitious material.
