Experimental and Numerical Compressive Strength of a Pervious Concrete

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.
