“…To minimize the harmful effects of elevated temperatures on concrete, suitable supplementary cementing materials (SCM) can be used. Various literatures showed that adding fly ash, slag, or silica fume significantly affect the performance of concrete and enhance its thermal properties [4][5][6][7][8]. On the other hand, the small size and tremendous properties of nanomaterials make them a good choice to be used as an additive to enhance the behaviour of cement mortar and concrete.…”

“…the degree of damage to concrete exposed to high temperatures. The strengthening of unfired cement paste results from the coexistence of the amorphous and crystalline C-S-H that binds particles into cohesive mass [48]. With rising temperature, a negligible and limited strength loss was observed at 300˚C and 450˚C then the strength loss markedly increases at the higher temperatures.…”

“…Concrete is a versatile construction material and offers numerous benefits, namely, strength, durability, economy, formability, and easy applicability. It is strongly argued that processes of concrete production are highly unsustainable, as cement production leaves an immense footprint on the environment due to intensive energy consumption, greenhouse gas emissions, and depletion of natural resources . The quest for finding cement alternatives and evolution of concrete technology has led to use of industrial byproducts as secondary cementitious materials (SCMs) commonly known as mineral admixtures.…”
