Abstract. The properties of self-leveling mortars (SLMs) in the fresh and hardened state are strongly affected by their formulation. In this study, the influence of three different quartz sands (different physical characteristics) was investigated in SLMs, as well as the replacement of these sands by crushed basalt filler.

Due to its physical and chemical characteristics sand is mainly used in the construction and glass industry. The analytical evaluation of the chemical composition and therefore the aptness for the intended uses make the comminution of quartz sand a prerequisite. FRITSCH offers a wide spectrum of suitable mills for this.

The physical (workability, fresh density), mechanical (compressive and flexural strength) and thermal (thermal conductivity) of different crushed sand concrete made are analyzed and compared to the respective controls. The use of rubber waste in crushed sand concrete contributes to reduce the bulk density and performance of sand concrete.

Sand is composed of all kinds of rocks and minerals, so its chemical properties greatly vary. Most sand is made of quartz, which is largely silicon oxide. Physically, sand is made up of tiny, loose grains of rocks or minerals that are larger than silt but smaller than gravel. Quartz is a very hard mineral, ranking a 7 on the Mohs hardness scale
