Mix cement with quartz sand

Quartz sand is mainly used by model makers, who pour decorative objects from appropriate concrete. However, there are areas where home improvement and craftsmen mix cement with quartz sand. For example, when grouting concrete or washed concrete slabs or for producing certain cement floors.

Mix cement with different aggregate

By mixing cement with other substances different building materials are produced. Typical building materials made of cement would be:

  • concrete
  • mortar
  • tile glue

Another area of ​​application would be cement floors. It does not necessarily have to be a cement floor according to the relevant standards. The biggest difference in the mentioned building materials, which are mixed with cement, are in the size of the surcharges. Thus, the maximum cross-section of the mortar aggregate is 4 mm.

Mix cement with fine quartz sand

In contrast, quartz sand has an even smaller grain size. This is in most of the offered quartz sand packages between 0.1 to 0.3 mm, but there are also grains that reach to about 2 mm.

Especially with filigree components can therefore achieve a particularly smooth, homogeneous surface with quartz sand. This is also the reason why cement is usually mixed with quartz sand in the manufacture of decorative items. There are also special quartz sand cement floors. These are made of white cement with quartz sand. However, these floor coverings are trowelled on an existing screed.

Properties of cement with quartz sand

The problem with mortar or glue that results when only fine quartz sand is mixed with cement is the much larger surface of the sand. This has a significant influence on the strength of the resulting mortar. But the surface is smoother.

In addition, of course, it's also a cost factor. The larger surface of quartz sand requires significantly higher cement requirements. In the production of decorative objects, a mixing ratio of the cement of 1: 2 is often stated. This is of course a significant cost factor.

Cement quartz sand mixture for dry grouting

In addition, quartz sand is also used for grouting. For example, with grout, only that this is usually still tempered to achieve greater flexibility with plastic granules. Craftsmen and do-it-yourselfers, however, make grouts from cement and quartz sand. But then no mixing water is added.

The cement-quartz sand mixture is used in grouting of washed concrete slabs and other concrete blocks laid outdoors. The cement is simply turned into the joints with the mixing ratio 1: 8 with quartz sand. In principle, this "mortar" then has similar properties as lean concrete on a larger scale: a high compressive strength.

Tips & Tricks

Immediately remove excess cement cross-sand mixture from the surface of the concrete blocks. These would lead to irregular discoloration. After stopping the mixture, you can also water the joints.
