Structural Evaluation and Performance of Portland Cement Concretes After Exposure to High Temperatures

Structural Evaluation and Performance of Portland Cement Concretes After Exposure to High Temperatures

We evaluated the "residual" thermal conductivity of Portland cement concretes (with characteristic compressive strength at 28 days, f ck, of 20 MPa and 50 MPa) at room temperature after heat-treating at 180 °C, 300 °C and 600 °C. The description of the geometry of the structure was carried...
