8th International Conference on Crack Paths Experimental and Numerical Compressive Strength of a Pervious Concrete Jonathan Duarte Oliveira a , Amanda Martins de Lima a , Luis Eduardo Kosteski a, *, Ederli Marangon a , Fernanda Bianchi Pereira da Costa a , Sabrina Vantadori b a MAEC, Federal University of Pampa, Alegrete Campus, Av. Tiaraju 810, 97546-550, Alegrete, Brazil. b Department of Engineering and Architecture, University of Parma, Parco Area delle Scienze 181/A, 43124, Parma - Italy Abstract The compressive strength of a specific mixture of pervious concrete is investigated both experimentally and numerically. The experimental campaign, performed at the Civil Engineering Laboratory of the Federal University of Pampa in Brazil, is performed to measure both the physical (density and porosity) and mechanical properties (compressive, tensile and flexural strengths and elastic modulus) of the material, whereas the numerical analysis is performed to simulate the mechanical behaviour under compression, by using the LDEM formulation implemented in the Abaqus/Explicit environment. The numerical results, both in terms of compressive strength and crack paths, are in a quite satisfactory agreement with the experimental ones. © 2025 The Authors. Published by ELSEVIER B.V.

Introduction According to the data provided by the Brazilian Institute of Geography and Statistics (IBGE (2021)), urbanization in Brazil has rapidly increased in recent decades, often without adequate planning, thus resulting in an increase of stormwater runoff, flooding, and depletion of underground reservoirs (Feng et al. (2021)). To mitigate such problems, a viable solution is the use of pervious concrete for road pavements, designed to restore the soil infiltration capacity. © 2025 The Authors.
