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.
