Fig. 10

Compressive strength after 28 days and bulk density of pervious concrete as functions of vibration duration. X-axis: vibration duration, t (s); left Y-axis: bulk density, ρ (kg/m3); right Y-axis: compressive strength, fcm,28 (MPa). Trend lines are shown only for statistically significant relationships. Linear fits (all mixes): fcm,28 versus t — slope = + 0.164 MPa per 1 s (95% CI [0.073, 0.256]), r = + 0.666, p = 0.0013, n = 20; ρ versus t — slope = + 4.499 kg/m3 per 1 s (95% CI [2.305, 6.694]), r = + 0.713, p = 0.0004, n = 20.
