...-compacted mortars and their correlations. Coarse particles of PP (at 4–10 US-Tyler and 10–20 US-Tyler) provided better mechanical behavior to composites than fine particles (20–50 US-Tyler), the latter being responsible for a rise in porosity. UPV can be used to predict the physical and mechanical...
