Yearly, some 350 million tonnes are used in the EU for a large variety of constructional purposes. The traditional methods for testing the strength of concrete require 28 days to complete. A method for quick analysis of concrete properties that predicts its final strength or measures the structure strength in-site while occurring is very desirable. Once available, such method would lead to lower construction costs through elimination of excessive wait times and design safety factors to compensate for uncertain quality control. During concrete hardening the dielectric characteristics of the paste change due to the changing water content of the cement paste. The aim of this research project is to develop a cheap, reliable and simple to operate monitoring system based on this physical phenomenon.
