Cure-State Monitoring of Cement-Based Materials using Microwave Near-Field Techniques
The compressive strength of concrete after 28 days of curing is the vital parameter in the structural design of concrete structures. In many practical applications, it is also of interest to obtain strength information before the prescribed 28 days. The parameter that influences the compressive strength is water-to-cement ratio (w/c). The (w/c) has an effect on both the relative gain of strength over time as well as the compressive strength after 28 days. In this study, the microwave reflection properties of several cement paste cubes having different (w/c) were measured on a daily basis for the first 28 days of the curing period at two different frequency bands (S-band and X-band). The primary goal of this investigation is then to correlate microwave reflection properties to cure-state, and hence the compressive strength of these samples on a daily basis.
