Mauermörtel

Mauermörtel is a plastic mixture used in masonry construction to bind building units together, such as bricks, stones, or concrete blocks. It serves multiple purposes: it distributes loads from the building units, seals the joints to prevent water and air penetration, and contributes to the overall stability and durability of the structure. The composition of mauermörtel typically includes a binder, aggregate, and water.

Common binders include cement, lime, or a combination of both (e.g., cement-lime mortar). Cement provides high strength and rapid setting, while lime offers plasticity, workability, and breathability. The aggregate is usually sand, which provides bulk and prevents shrinkage. Water is essential for the hydration of the binder, initiating the chemical reactions that harden the mortar. Additives can also be incorporated to modify properties like water retention, frost resistance, or color.

The preparation of mauermörtel involves thoroughly mixing the dry components with water to achieve a homogeneous, workable consistency. The mortar is then applied to the building units and compressed, filling the joints completely. As the water evaporates and the binder hydrates, the mortar hardens, creating a strong bond. The type of mauermörtel used depends on factors such as the building materials, structural requirements, and environmental conditions. Different mortar strengths and properties are specified by standards for various applications.
