Parametric study on the effect of temperature on properties of engineered cementitious composites using induction furnace slag as a partial replacement for river sand

This paper studies the effect of temperature on Engineered Cementitious Composites (ECC) properties using induction furnace slag (SS) as a partial replacement for river sand (RS). Replacement percentages are between 5 and 65%, with an increment of 15% by dry weight of RS having various particle sizes (2.36 mm, 1.18 mm and 0.6 mm). The cubes are subjected to various temperatures (200, 400, 600 and 8000C) in a muffle furnace. After heating, visual observations and strength deterioration of RS and SS ECC are assessed. The extent of postfire damage is determined using the UPV test. SEM and XRD are used to identify the changes in the microscopy morphology and the chemical compositions. It is clear from the test findings that with SS partially replacing RS, the heat insulation capacity of ECC is enhanced. Based on test results, the ECC up to 50% SS as an RS alternative performs better at all temperature exposures.
