Abstract:

This report outlines an experimental plan designed to quantify the effect of elevated temperature on the mechanical properties of high-strength concrete. The experimental program will examine the influences of the following factors: (1) different steady-state test methods, (2) rates of heating, (3) water-to-cementitiou materials (w/c) ratios (and implicitly compressive strengths), (4) inclusion or absence of silica fume (and implicitly paste density). These effects will be studied through 148 test combinations developed using a full factorial experimental design. The highest strength concrete to be tested is 95 MPa, and the lowest strength is 28 MPa.
