SAND

There are two kinds of sand which may be procured for mortar, as follows:

A. Pit sand or bank sand.

B. River or lake sand.

The difference between these two types of sand is as follows:

The river sand is generally free from any clay content. The grains are less angular and in general it is less desirable for use in mortar.

Pit or bank sand usually has a small clay or loam content which must be washed from it in order to get the particles of sand clean. The particles of sand are angular and somewhat rough and therefore make it much more desirable for mortar making.

Sand which is used for the hearth and also for the area around the fireplace should have a small proportion (approximately 10 to 15 percent) of clay content, in order that there may be some cementing quality in this mixture— otherwise the sand will not pack and become firm under foot, especially around the fireplace.
