Measuring concrete strength The conventional method for monitoring concrete strength involves pressing cubes that cure outside the construction itself. These cubes have a different temperature than the construction concrete so their strength develops at a different rate, making this a poor strength indicator.<\/p>\n ConSensor does it differently. In the lab, ConSensor starts by making calibrations of strength in relation to maturity and conductivity. On site, the contractor uses these calibrations to accurately determine the concrete strength.\u00a0<\/strong><\/p>\n The main difference between ConSensor and other systems is that ConSensor uses 2 measurement methods:<\/p>\n Why does ConSensor offer two methods? First, as a failsafe, and second, to monitor the long-term integrity of concrete.<\/p>\n When you turn on the measuring device sometime after the pour, the system measures too little weighted maturity, giving you an estimate of the concrete\u2019s strength that is too low.<\/p>\n In contrast, when using the conductivity method, turning on the device too late isn\u2019t an issue\u2014it gives you a correct strength value based on the actual conductivity at that moment.<\/p>\n Used together, the two measurement methods offer more certainty about the strength of the concrete and the setting process.<\/p>\n And in the long term, measuring the concrete\u2019s conductivity serves as an indication of the concrete\u2019s condition. An increase in conductivity after many years indicates an ingress of water and possibly ions, signaling the need to investigate the concrete\u2019s integrity.<\/span>\u00a0<\/span><\/p>\n Let\u2019s compare the methods for creating a calibration curve.<\/p>\n
