Szukana fraza: [Abstract = "The dry unit weight, porosity, compressive and flexural strengths, and velocity of ultrasonic waves with different transducers \- which presents the non\-destructive technique \- were evaluated. Rubberized concrete mixtures showed increases in porosity with lower dry unit weight compared to the control concrete. Compressive strength, flexural strength and ultrasonic velocity obtained by all transducers decreases with increasing RW content."]
