LIGHTWEIGHT CONCRETE FOR CONSTRUCTION
There is a wide range of applications for lightweight concrete. Structural lightweight concrete gets its reduced weight from Poraver® and it is used for components and wall and floor elements. Depending on the formulation, the compressive strength of regular concrete according to DIN 1045 can be achieved. Load-bearing parts can be designed with slimmer dimensions since the dead weight of the overlying component parts determine their dimensions. This offers a new degree of design freedom in building construction, civil engineering and bridge construction.
LIGHTWEIGHT AGGREGATE FOR PLASTER AND DRY MORTAR
Poraver® is the preferred lightweight aggregate for dry mortar and construction chemical products. The innovative lightweight filler with its positive characteristics meets even the most demanding product requirements. Poraver® is ideally suited for combination with lime, cement and other binders. Its spherical grain shape and low density optimize the formulation as well as the material properties of your products.
LIGHTWEIGHT PANELS WITH
Poraver® is the ideal basis for various types of panels. The low weight, high rigidity and easy processing in particular have made high-quality lightweight panels, kitchen worktops, acoustic panels and facade carrier boards with Poraver® very popular. Panels with Poraver® can do even more: They are not sensitive to heat and cold, highly resistant to humidity and they have very good acoustic properties.
MINERAL CASTING, POLYMER CONCRETE AND THERMOSET
The terms “mineral casting” and “polymer concrete” are sometimes used synonymously. A grading curve which also contains coarse aggregates (larger than 4 mm) is used below for polymer concrete. In mineral casting, rather fine and high-quality fillers are used. This also yields a variety of applications.
Conventional mineral casting and polymer concrete structural components generally have rather high densities (2000 – 2300 kg/m³) because of their mineral fill. When Poraver® is used, the thickness of such building components can be reduced by up to 70 %.
FUNCTIONAL RESIN FILLER
Poraver® is a suitable replacement for traditional resin fillers such as Calcium Carbonate and other engineered mineral filler systems. Poraver®’s various size ranges and choice of grades gives thermoset product engineers great flexibility when designing and formulating resin mixtures and slurries.
FILLS FROM EXPANDED GLASS
Poraver® expanded glass is purely mineral and poses no environmental or health-related risks and is ideal for fills with sustainable characteristics. Compared to expanded polystyrene, PORAVER® is non-combustible and unproblematic in later disposal. The spherical granules are very lightweight and yet pressure-resistant. They are free of harmful materials such as VOC or fibres, stable over the long term, can be easily processed and do not offer a breeding ground for pests and mold. Poraver® granules can be used as loose bulk thermal insulation and as cement- or resin-bound fill for pressure loading requirements.
Our lightweight Poraver® expanded glass is an ideal 3D printing material. The small spheres have only 20 % of the weight of sand and can be used in the common additive production process with 3D powder bed printers with a variety of binders, in selective laser sintering (SLS) or for the concrete 3D printing (contour crafting). With its low density and high strength, Poraver® promises a significant reduction in the weight of printed shapes and large parts. Areas of application include prototyping, the production of components as well as direct mold making. Poraver® is also particularly suitable as an aggregate for the 3D printing of concrete. Entire buildings can be easily produced in this way with integrated insulation.
CELLULAR COMPOSITES/SYNTACTIC FOAMS
Automotive engineering calls for materials with a light weight and high strength along with predefined deformation properties. Innovative mineral foam composites with Poraver® expanded glass granules in a plastic or metal matrix meet this requirement and are used as a support core in hybrid crash absorber structures or in lightweight chassis. This is based on the use of fillers with a high pore volume which function as placeholders in a matrix and which thus make a low-density material possible.
PAINTS AND WALLPAPERS
Poraver®, as a structural grain, gives modern wall paints something extra. A variety of surface appearances and textures are possible, depending on the grain size. The coatings made with Poraver® can be easily applied using a wipe, brush or spatula technique. Because of its stable, lightweight and round grain, Poraver® is ideally suitable for this application as a texture component. Wallpapers can also be finished with white or colored Poraver® to create distinctive surfaces.
