Landfill suitability and 24 recyclability Due to its extreme durability, polymer

Application-orientated ACO materials concrete helps to avoid waste. It can be added to the recycling process and is classified under waste code 170107 ACO polymer concrete – (mixtures of concrete, clay bricks, tiles one idea ahead and ceramics) in accordance with the The special material composition and state-of-the-art production “European Waste Register Regulations” technology give polymer concrete its outstanding properties. for mineral waste. ACO polymer concrete products have high strength values and a low weight. ACO polymer concrete is waterproof, allowing water to dry quickly, frost damage is eliminated. The smooth surface of ACO polymer concrete allows water and dirt particles to run off quickly and is easy to clean. Polymer concrete is also resistant to aggressive media without requiring additional coatings and can be used versatilely and durably even under extreme conditions. ACO materials
