Formwork blocks - overview and types of use

Under shuttering stones are specially made stones known that convince by their appearance and special use. Formwork blocks have a hollow core, inside there is one or more air chambers. These are open to the top and bottom of the stone. These formwork bricks are used more and more often in masonry or bricklaying, because their simple processing can convince more and more.

Formwork blocks can consist of different materials. The classic shuttering blocks are made of concrete or lightweight concrete. But even newer materials such as wood or polystyrene are being used more and more often. These stones convince by their excellent insulating properties.

The variety of shuttering stones

Formwork blocks are available in many forms and materials. The most common materials are concrete and lightweight concrete. The stones offer the classic properties of solid stones, but convince by their much simpler processing and their lighter weight. New materials such as polystyrene or polystyrene offer, in addition to the already mentioned properties of concrete shuttering blocks, an additional, particularly good insulation of the walls. Shuttering stones made of these materials are particularly light and can therefore be processed very well by inexperienced craftsmen with only a few previous knowledge. New on the market are formwork stones made of wood chips. In addition to simple processing and very good insulation, they also ensure a pleasant indoor climate all year round. Here, the positive properties of formwork blocks are optimally combined with the corresponding material. Properly constructed, formwork blocks can be used to build a house with passive house qualities.

The use of shuttering stones

Formwork blocks are a building material that is extremely easy to handle. Shuttering stones are particularly suitable for individual walls and cellar walls, but also for the entire house construction. A thick concrete foundation is not absolutely necessary. If the ground is stable enough, a simple concrete slab is also suitable for applying the first layer of formwork bricks. In the first layer, a layer of mortar should be used to connect the formwork blocks to the ground and to align the stones perfectly horizontally. For the other layers no mortar is needed. The stones are aligned with each other precisely by the integrated tongue and groove system. For load-bearing walls reinforcing bars can be inserted for added stability. Free-standing and load-bearing walls should already be filled with the first fluid concrete after reaching a height of about 50 centimeters. This procedure facilitates the introduction of the wall filling in the lowest layers.
