Explanation/Annotation:For non-destructive testing of concrete strength by the spalling methods of rib and breakaway with spalling according to the state standard 22690.
Detailed model description:Distinctive feature of device is the electronic measurement of force, providing the high accuracy of force measurement, the indication running value applied load with fixation of peak value, as well as indication of loading rate in testing. The device is being completed by universal tool attachments, providing the concretes testing, as a method of rib spalling, and breakaway method with spalling. Readiness time not more than 5 minutes. With the aim of increasing the accuracy and capacity of examinations in device, according to testing method, the option to install following parameters is provided: concrete kind, condition of hardening of concrete, aggregate size, anchor dimension-type. The parameters input is carried out in the online mode with device keyboard, the coefficients choice for automatic computation of concrete strength according to results of load (the bear load in case of rib spalling or fragment pull out of concrete) is thereby ensured. The device has the non-volatile memory and the condition, providing the establishment 10 individual calibrating dependences. The put in the memory of device the measuring results ìàðêèðóþòñÿ date and time of measurement.
