Properties of Andesite
Andesite is a fine-grained volcanic rock that typically forms from the cooling and solidification of magma or lava. It is part of the igneous rock family and is commonly found in the Earth's crust, often associated with volcanic activity.
The following table provides a list of andesite properties in both SI and US customary/Imperial units at normal temperature and pressure (NTP).

| Physical Properties | Metric |
|---|---|
| Density | 2400 - 2900 kg/m3 |
| Porosity | 10 - 15% |
| Mechanical Properties | Metric |
| Young’s Modulus (E) | 20 - 60 GPa |
| Thermal Properties | Metric |
| Thermal Conductivity | 0.6 - 1.26 W/m·K |
| Specific Heat Capacity (Cp) | 330 - 245 J/kg·K |
| Coefficient of Thermal Expansion (αL) | 7×10-6 1/°C |
Unless stated otherwise, all values are taken at room temperature (approximately 20°C or 68°F) and 1 atm pressure. (1 atm = 101,325 Pa)
