As a responsible service provider, we see it as our duty not only to give the best for our customers and employees. Ethically correct and transparent business processes, the protection of the environment and regional social commitment are also important components of our corporate identity. Fly ash Fly ash tweaks concrete for high performance Our hard coal fly ash is very much in demand among our customers from the construction materials industry. Fly ash can be put to many different uses. Fly ash can bring its strengths fully to bear above all in the production of concrete and cement. In the concrete, the fine round particles of fly ash act like small ball bearings, improving the water demand. The concrete is easier to work and, in the case of shotcrete and high performance concrete, can be better compacted. The strength of the concrete is also significantly improved because the fly ash particles fill out the cavities in the concrete. Furthermore, the pozzolanic reactivity, i.e. the continued reaction of the fly ash with the calcium hydroxide from the cement and water in the concrete, has a positive long-term effect on the strength and resistance of the concrete. Due to this ongoing reaction, which usually continues for years, the concrete becomes increasingly more compact, stable and durable. This makes it more resistant, for example against the effects of acid or sulfate. Fly ash thus lends the concrete properties that are required especially for bridges, tunnels, cooling towers, sewers and foundations. To ensure its quality, we have the material properties of the fly ash regularly examined in our Construction Materials Laboratory. How is fly ash produced? Downloads Project "Überseequartier" Bottom ash Environmentally friendly lightweight aggregate Light, versatile in use and climate-friendly – bottom ash is an easy to use construction material which is used mostly in the production of concrete goods, in horticulture and landscaping, and as filling material in road building. The individual grains have a porous structure that gives them material characteristics similar to other natural and artificial lightweight aggregates. This combines with a high level of environmental compatibility: The use of bottom ash conserves natural resources; moreover, no additional energy is consumed to produce it. On top of that, bottom ash is easily recycled. With interim storage, an average material moisture level of 20 to 25 percent can be attained. How is bottom ash produced? FGD gypsum Ecologically valuable and versatile A variety of environmentally friendly gypsum construction materials of the highest quality are made with FGD gypsum from EP Power Minerals. As building material, gypsum can be rated favorably from a physiological viewpoint because it has a regulative effect on humidity. In Germany, gypsum is mainly used for interior finishing. Around 75 percent of gypsum output is used for plasterboard, building plasters like facing plaster, or filling compounds. The cement industry also uses gypsum as a curing retardant, and the ceramics industry uses it to make casting molds. How is FGD gypsum produced? Storage and Transport Solutions for Power Plant By-products Efficient logistics chains are the key to success for every project. Our customers always expect to receive their products on time and in the required quality and quantity. Therefore we do everything to ensure their security of supply. With flexible logistics strategies, a wide range of storage facilities and large silo capacities, we have the know-how and assets needed to move our products rapidly and reliably. On the one hand, this enables us to meet our disposal obligations towards our power plant customers. On the other hand, access to comprehensive silo capacities and transport routes enables us to ensure the best possible security of supply for our building materials customers - even in the months when the power plants tend to produce less fly ash and other power plant by-products. Compliance with all environmental and safety regulations is just as important to us as reliable deliveries to our customers. That is why we regularly check and optimise our logistics concepts. Our goal is to shorten transport routes, to link routes and, for example, to utilise vehicles in a well thought-out way so that the environment benefits most of all. In the last five years, this has reduced our emissions by 25 percent. Short transport routes Optimum capacity utilization Linking routes Use sources of partner companies Do you have any questions about our power plant by-products? Then please feel free to contact us.
