13 Μαρ 2014 · The variation of thermal, mechanical, deformation, and spalling properties with temperature for different types of concrete are presented. Variation in thermal conductivity of normal strength ...
8 Φεβ 2021 · This paper presents a critical review on the thermal and mechanical properties of concrete and its constituents exposed to a range of elevated temperatures. The effect of temperature on different types of cements, coarse aggregates, fine aggregates and secondary additives have been discussed.
1 Νοε 2020 · The thermal and mechanical properties of coarse aggregates, cement mortar, and cement concrete specimens of varying mix proportions were studied after exposure to a range of high temperatures.
13 Μαρ 2014 · Thermal properties that govern temperature dependent properties in concrete structures are thermal conductivity, specific heat (or heat capacity), and mass loss. These properties are significantly influenced by the aggregate type, moisture content, and composition of concrete mix.
paper aims to define the thermophysical properties of a high-strength concrete, compare the discovered performance with the conventional concrete properties.
1 Νοε 2018 · Thermal conductivity, specific heat and thermal diffusivity are deemed thermo-physical properties of concrete. Thermal conductivity is the most important thermal property that affects heat transfer by conduction through concrete [6] .
Thermal expansion properties are important to the fire performance of concrete structures in two ways: The conductivity of concrete is determined by the conductivities of its constituents.
