Abstract

To assess the curing of concrete, and especially concrete linings (16) used in tunnel construction and called shotcrete, for monitoring the early age of concrete strength development, a system (30) is provided that measures thermal variations in the surface (18) of the lining (16) at discrete or contiguous test regions (82, 84, 86). The thermal data, arising from heat migration from within the concrete, is compiled into a plurality of thermal profiles. A microprocessor (40) is configured to compare and contrast individual thermal profiles against a reference profile or discrete data points. The system (30) also includes a ranging and position device, such as a laser theodolite (60), that cooperates with the microprocessor (40) to assemble a three-dimensional map of time-varying thermal profiles in the context of sections of a tunnel (10). Each thermal profile therefore provides an indication of the extent of hydration and hence the strength developed in the concrete lining, with the microprocessor (40) controlling collection of data, comparison of profiles and a real- world output indicative of current and future lining strength. The reference profiles are adaptable to reflect varying base formations for the tunnel (10) or cavity that is to be lined. The reference profiles also take into account variations in concrete composition, depths of the concrete lining and environmental conditions that may affect hydration.
