Research And Development Services And Related Consultancy Services - Fe 08.0280/2024/Igb - Increasing The Durability Of Grinding Textures By Applying For Strength -Enhancing Inorganic Products In A New Building. In The Course Of Improving The Sustainability And The Environmental Effects Of Our Traffic Routes, Noise Reduction Is Becoming Increasingly Important. The Concrete Construction Has Been Developing Noise -Reducing And At The Same Time Gripy Surface Textures For Years. A Good Noise Reduction Can Be Demonstrably Achieved By An Acoustically Effective Grinding Texture Of The Concrete Surface. Especially Immediately After The Production, These Surfaces Have High Noise Reduction Values, Which, However, Decrease During Use. The Predominant Reason For This Is The Mechanical Stress Due To The Traffic, Since The Lines Of The Texture Wear Through The Strong Mechanical Stress. While The Decorative Resistance, Which Is Sufficient In The Surface In The Surface, Have An Adequate Wearing Resistance, Experience Has Shown That The Muzzle Matrix On The Top Level Is The Weak Point. The Aim Of This Research Project Is Therefore To Improve The Durability And Thus The Noise -Mediating Effects Of Grinding Textures On New Concrete. For This Purpose, The Various Possibilities Of An Additional Consolidation Of The Grinding Stand By Chemically Effective Substances, As Are Known From Other Applications For Remuneration Of Cement -Bound Areas, Are To Be Examined In Terms Of Laboratory Technology. The Focus Is On The Application On Surfaces Of Routes With A Newly Produced Concrete Ceiling With Grinding Texture. In The Case Of Positive Results, An Expansion Of The Application To Existing Routes With Subsequent Grinding Is Conceivable. As A Result, An Assessment Of The Use Of Strength -Increasing Substances With Regard To Permanent Noise Reduction, Material Parameters And Environmental Aspects Should Be Carried Out. In The Event Of Positive Results, Further Examinations And Initial Practical Applications Can Be Planned And Designed.
