Rakennuslaasteja

Rakennuslaasteja, commonly referred to as construction mortars, are essential materials used in building and renovation projects. They are typically composed of a binder, such as cement or lime, a filler material, like sand or crushed stone, and water. The proportions of these ingredients are carefully controlled to achieve specific properties suitable for various applications.

The primary function of rakennuslaasteja is to bind building units together, such as bricks, stones, and blocks, forming a stable and cohesive structure. They also serve to fill gaps between these units, providing a uniform surface and improving insulation. Mortars can also be used for rendering and plastering walls, creating decorative finishes, and for grouting tile joints.

Different types of rakennuslaasteja exist, each tailored for distinct purposes. Cement-based mortars are known for their strength and durability, making them suitable for load-bearing applications and exterior work. Lime-based mortars are more flexible and breathable, often preferred for historic buildings and internal finishes. Ready-mixed mortars are also available, offering convenience as the components are pre-blended and only require the addition of water. The setting and hardening process of mortar involves a chemical reaction, typically hydration, where water reacts with the binder to form a solid matrix. Proper mixing, application, and curing are crucial for ensuring the performance and longevity of mortar in any construction project.
