expansion

Search the forum,
Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions.Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, molecules begin to vibrate and move more, usually creating more distance between themselves. Substances which contract with increasing temperature are unusual, and only occur within limited temperature ranges (see examples below). The relative expansion (also called strain) divided by the change in temperature is called the material's coefficient of linear thermal expansion and generally varies with temperature. As energy in particles increases, they start moving faster and faster weakening the intermolecular forces between them, therefore expanding the substance.

    Advice on expansion gaps

    Evening all, i have my floor ready to tile and have an expansion gap all round the perimeter. So, when I come to the gaps do I fill them with silicone and close the gap up with the tile on top? At the minute I have 5mm all round the edge of my insulation and SLC. Thanks in advance, Dan

    pipe expansion gap

    Hi I've laid a ceramic tile floor, however I'm concerned that a tile is too close to a water pipe that is coming out of the floor. There is a gap of around 1.5mm between the tile an pipe. The room is 1.5metres squared. Is this likely to be a problem? If so what's the best method to cut the tile...
