• Abstract:

  Particle density is one of the most important values to characterize lightweight aggregates. Various test methods yield various densities, because the grain volume is defined by the test fluid method used to determine the volume of the aggregate particles. Several standardized test methods are analyzed and compared with each other. The test results are reported. An improved test method is presented, which embeds the aggregate particles in cement paste to simulate the real conditions in fresh concrete.
