Abstract
AbstractThe modulus of elasticity is an important property for evaluating the mechanistic response of any material under load, and porosity influences the rheological, mechanical, and hydraulic properties of pervious concrete. The relationship between porosity and modulus of elasticity of pervious concrete has not been well researched. In this study, pervious concrete cylinder specimens were prepared for a range of porosities and compression tests were performed to determine the moduli of elasticity. Secant moduli of elasticity at five different stress levels (i.e., 2.2, 2.8, 3.3, 3.9, and 4.4 MPa) were calculated from the load-deformation data of the compression tests. Three performance zones were proposed for estimating the modulus of elasticity based on porosity at the stress levels of 2.2 and 2.8 MPa, i.e., lower, average, and upper. These performance zones provide designers with more information based on the variability and heterogeneous distribution of porosity in a pervious concrete section for risk-based assessments. While more research is required for comprehensive characterization of pervious concrete, the modulus of elasticity equation in the lower performance zone might provide an initial performance assessment of pervious concrete until its components can be better characterized.
