Evaluation of possibilities to apply laser scanning for estimation of conditions of concrete

Abstract

Periodical surveys of concrete structures, performed within geodetic monitoring, may be implemented using laser scanners. Similarly to a tacheometer, the scanner determines spatial co-ordinates (X, Y, Z) of surveyed points, specifying the distance and angles. Besides the speed of operations, the parameter, which mostly differentiates the scanner from the tacheometer, is registration of the 4th co-ordinate – an intensity of reflectance of the returning light signal, emitted by the scanner. The analysis of recorded values of that additional, 4th co-ordinate may be applied in diagnosis of conditions of structures. The paper presents evaluation of possibilities to utilize results of laser scanning for determination of conditions of outer surfaces of construction of a water dam – variations in porosity and resistance of concrete.
