Abstract
The subject matter described herein includes methods, systems, and computer program products for measuring the density of a sample construction material. According to one aspect, a nuclear density gauge is disclosed for measuring the density of a sample construction material. The material measurement gauge includes a radiation source positioned for emitting radiation into a sample construction material. A radiation detector is positioned apart from the radiation source and configured to detect radiation from the sample construction material and to produce a signal representing the detected radiation. A non-nuclear moisture property detector is configured to determine a moisture property of the sample construction material and to produce a signal representing the moisture property. A material property calculation function is configured to calculate a property value associated with the sample construction material based upon the signals representing the detected radiation and the moisture property.
