| Building on expansive soils requires arrangements that generally depend on the expansivity of the soil, but these arrangements often generate some important over costs. |
| They provide resistance to frictional wear, corrosion resistance, nonmagnetic characteristics and, in some alloys, low thermal expansivity at ambient temperatures. |
| The comparatively high thermal expansivity of aluminium leads to looseness unless the steel has a similar coefficient of expansion. |
| The local compression created by the electric field can be related to the expansivity modulus, K, by this expression. |
| This means that thermal expansivity will drive the phase separation process. |
| However, as will be shown below, the volume expansivity of certain fluids, such as hydrocarbon blends and silicone oils, is large enough to be of importance. |
