compressive strength at elevated temperatures and electrical resistivity of Seashell/Lumashell-based concretes

The first aim of this study was to assess the behavior of shell-based concretes developed using Seashell/Lumashell powders as cement replacement with the dosage of 0, 2.5, 5, 10, 15, 20 and 25% by weight. The investigated mechanical properties included the compressive strength (CS) at different elevated temperatures (0, 200, 400, 600 and 800 °C) and water porosity (WP) and electrical resistivity (ER) at room temperature.
