decreases with increasing elevated temperature. The vapor pressure occurs due to the evaporation of the adsorbed and capillary water when the temperature is between 25 and 200 °C and thereby it tends to reduce the strength of the concrete [ 12 ]. The

solvents and have excellent physiochemical properties such as low vapor pressure, good thermal stability, and tunable viscosity [ 24 , 25 ]. ILs result from the combination of organic cations and anions and are usually liquids at room temperature [ 26

partial agreement with the results of Snyder et al. [ 9 ]. They have observed the presence of CoSb, besides CoSb 2 as a product of CoSb 3 decomposition. Our result is probably an effect of higher Sb vapour pressure during the experiment. The Sb 4 vapour

alternatives to hazardous organic solvents because of their unique properties such as low melting temperature, high thermal stability, wide liquid phase range, non-flammability, and low vapor pressure [ 19 ], it still shows drawbacks such as toxic, complicated

. The properties of ILs and DESs can be designed by changing the composition of materials. Besides, they have almost no vapor pressure so there are less harmful to operators and environment. But according to the published literatures, some of the

cracks and explosive spalling. Lower porosity and dense microstructure are responsible for the poor behavior of MK concrete at elevated temperatures. Due to the vapor pressure in dense pore structure, explosive spalling was observed between 450 and 500 °C
