ABSTRACT:
A system and method for determining the air-void or aggregate content of a concrete specimen according to the point count and modified point count method utilizing coordinate data collected during linear traverse method inspection. A computer operates a computer driven stage containing the concrete specimen under a microscope, whereby positional data is transmitted to the computer. The computer controls the linear traverse pattern of the stage under the microscope, although the operator has the option to manually increase or decrease the traverse rate during the inspection cycle. The computer automatically records linear traverse coordinate data for the entire traverse pattern. An operator records in the computer beginning and ending coordinate data for air-voids or aggregates encountered on the traverse pattern from which the air-void or aggregate content is calculated according to the linear traverse method. The computer then calculates the air-void content according to the point count and modified point count methods using the linear traverse coordinate data and the beginning and ending coordinate data of air-voids recorded by the operator.
