concrete maturity meter

VEDA-THERMA is a temperature monitoring unit with temperature data logging system at user defined interval, mostly required for mass concrete. It measures the temperature of concrete from the time of concrete casting, its precise temperature sensors are inserted inside the fresh concrete at the time of casting, and it continues to log the temperature data till the heat of hydration completes. This practice provides procedure for estimating concrete strength by means of maturity method. The maturity index is expressed either in terms of the Temperature-Time factor or in terms of equivalent age at a specified temperature. This practice requires establishing the strength-maturity relationship of the concrete mixture and recording the temperature history of the concrete for which strength is to be estimated The recording time interval is 30 minutes . Complying with various National and international standards like ASTM C1074
