What are the good properties of sand

Crushed sand: characteristics and price

Crushed sand is a popular, but also very expensive building material. Its costs are often more than double that of normal building sand. The reason for this is the special and useful properties of the crushed sand. It is precisely these properties that make it an indispensable building material, especially in road construction and horticulture. We tell you what crushed sand is, how it differs from normal construction sand and what you can best use it for.

What is crushed sand?

Crushed sand or crushed gravel belongs to the group of broken minerals. It does not arise naturally, but is the result of rock crushing. Due to the artificial production, crushed sand has a different grain shape. This form of broken aggregate has a size of 0 to about five millimeters. Up to a size of 0.25 millimeters one speaks of fine crushed sand. Because the grains of crushed sand are so small, it is often called crushed sand. The artificial production also results in other physical and static properties for crushed sand.

What is crushed sand used for?

As a bulk material, crushed sand has many different areas of application. For example, it is used in road construction. There it is added as an aggregate, i.e. as an asphalt addition, and thanks to its irregular and often angular shape, it reinforces the stability of the sand.

Crushed sand is also popular in horticulture due to its irregularity. For example, it is often used as joint sand when building terraces or paths. The advantage over normal sand is that crushed sand makes it difficult for weeds and other unpleasant plants to pave their way through it. Although it does not completely prevent the plants from growing, it slows it down significantly.

In parks, crushed sand is often applied as the top layer, which is then shaken up and then forms a stable, long-term floor covering. Here, too, it also prevents weeds from growing.

Crushed sand is also used in equestrian sports, where crushed sand is used to fill riding arenas or riding tracks. Because: crushed sand is considered to be particularly non-slip and is therefore ideal for equestrian sports.

Crushed sand: what is the difference to normal construction sand?

Crushing sand and construction sand are fundamentally different. On the one hand, crushed sand has a much coarser and more uneven grain than regular construction sand. On the other hand, crushed sand can be larger than construction sand: If the diameter of crushed sand is up to five millimeters, construction sand is usually no larger than two millimeters. In addition, crushed sand is used differently than construction sand. Crushed sand is often used as joint sand or aggregate, whereas construction sand can also be incorporated into plaster thanks to its finer texture.

This is how crushed sand is processed

If crushed sand is used as joint sand, it should definitely be wet or damp during processing. This has the effect that the sand seeps into the joints more easily. First apply a thin layer of crushed sand and then apply the covering (such as paving, stones or slabs) on it. Then fill the joints with crushed sand and then wait until the sand hardens. From now on the underground is safe to walk on.

How is crushed sand made?

Crushed sand can be made either from natural stone or from rubble. So it is not a naturally occurring building material, but arises when larger stones are broken out of rocks. Basalt, granite or sometimes rubble serve as the basis for crushed sand.

Crushing sand: it has these properties

Due to its many good properties, crushed sand is a very popular and unfortunately also expensive building material. In building construction, among other things, crushed sand is used for slip resistance, for stronger static cohesion, is permeable to water, slows the growth of weeds and other plants and prevents ants from removing the sand.

How expensive is crushed sand?

Crushed sand is usually more expensive than normal types of sand. You can buy the building material in all hardware stores, gravel works or directly from sand dealers. The crushed sand is then usually sold in large containers and billed per cubic meter. A cubic meter of crushed sand costs between 36 and 90 euros. In terms of kilo prices, 25 kilos of crushed sand is around 3.80 euros. In contrast, 25 kilos of regular building sand cost just 1.60 euros, around half.

Why is crushed sand so expensive?

The price for crushed sand is often more than twice as high as for normal construction sand. This is due to the fact that the building material has to be manufactured artificially and at great expense. In addition, crushed sand has a higher density than construction sand - in other words: The weight that has to be transported is much higher than that of construction sand. But there are also cheaper types of crushed sand. If the building material was made mechanically from rubble that had already been sorted, the costs would be significantly less for crushed sand made from natural stone.

When calculating the costs of your construction project, it is important that you calculate the exact weight of the sand from the density of the crushed sand - this is the only way to know how much crushed sand you will need and pay for in the end.
