Cement. The essential for every building, landscaping, refurbishment, new build, extension, plastering, paving, walling, retaining, drainage, groundworks, fencing, pointing.....lets face it, anything really involving building or making something.

 

Cement is a fine, soft, powdery-type substance. It is made from a mixture of elements that are found in natural materials such as limestone, clay, sand and/or shale. When cement is mixed with water, it can bind sand and gravel into a hard, solid mass called concrete.

Did you know? Four essential elements are needed to make cement. They are Calcium, Silicon, Aluminum and Iron. Calcium (which is the main ingredient) can be obtained from limestone, whereas silicon can be obtained from sand and/or clay. Aluminum and iron can be extracted from bauxite and iron ore, and only small amounts are needed.

Cement is usually grey. White cement can also be found but it is usually more expensive than grey cement.

Cement mixed with water, sand and gravel, forms concrete.

Cement mixed with water and sand, forms cement plaster.

Cement mixed with water, lime and sand, forms mortar.

Cement powder is very, very fine. One kilo (2.2 lbs) contains over 300 billion grains, although we haven't actually counted them to see if that is completely accurate! The powder is so fine it will pass through a sieve capable of holding water.

Tip: cement should be stored in a dry area. If it gets wet or damp the powder will turn into a hard lump.
