Solid Precast Concrete, pre-stressed slab

Product information

The solid precast concrete, pre-stressed, slab has many advantages. The built in tension of high-strength multi wire strands in combination with the thickness of the slab leave room for plumbing as well as creating a sturdy construction without the need of post

shores. This allows for a shorter construction time as well as a safer work environment.

The solid pre-stressed slabs come in lengths up to 10 meters and widths up to 3,2 meters. If the customer wish, the products can be completed with conduits for electrical wires or plumbing. This, however, is not included in the EPD.

All products are manufactured indoors, which ensures a high and even quality throughout the year.

Since each product is custom made new drawings are made before the production process starts. The products are optimized for each project. In this phase of the project, the customer has the opportunity to make choices that affects the entire lifecycle of the building, e.g. reference service life, product dimension etc.

Raw materials are purchased and transported to the factory. The raw material that has the biggest impact on the climate is the production of cement. During the production, in the cement factory, a process called calcination is taking place. During the calcination, CO2 is released from the limestone. The finished concrete, however, can retrieve some of this CO2 during its lifetime. Up to 1/5 of the CO2, which is released during the cement production, can be retrieved by the concrete. This is an important fact to consider when making a life cycle analyses for an entire building. It has not been considered in this EPD since it does not include the end of life perspective.

In the factory, a mold is prepared. It can be made of different types of materials such as steel or wood. This includes making the holes and openings that are needed for e.g. installations and windows.
