Experimental Investigation on Color Change and Weight Loss of Steel Fibre Reinforced Concrete when Exposed to Elevated Temperature

Received Date:05 January 2024, Accepted Date:02 February 2024, Published Date:23 February 2024


Objectives: This study mainly focuses on different steel fibres content behaviour, when exposed to various temperature. Methods: In this experimental investigation, the prism specimen of size 500 x 100 x 100 mm with steel fibre content of 0% and 1.5% were exposed to temperature of 100 °C, 300ºC, 500 °C and 700 °C. The Temperature-Time graph was obtained as an outcome of the experiment. Color change and weight loss of specimens at different temperatures was assessed. Findings: The RSM weight loss prediction model has been proposed for specimen before and after exposure of temperature. Color changes at 100 °C, 300 °C, 500 °C and 700 °C was observed to be no color change, red, grey and whitish grey respectively. Mass loss of 0% steel fibre concrete prism at 100 °C, 300 °C, 500 °C and 700 °C was found to be 2.17%, 4.33%, 4.24% and 6.55% respectively. Mass loss of 0% steel fibre concrete prism at 100 °C, 300 °C, 500 °C and 700 °C was found to be 0.61%, 4.51%, 5.66%, and 6.27% respectively. Novelty: Very few studies have been conducted on the combination of color change and weight loss of the specimen. Weight loss prediction model is the novelty of this study. The RSM prediction model clearly indicates that the response values are 97.21% and 96.12%, where the model is fit for weight of specimen before and after exposure to temperature respectively.
