Rissweiten

Rissweiten, also known as crack width, refers to the width of a crack in a material, most commonly discussed in the context of concrete structures. It is a critical parameter for assessing the durability and serviceability of a structure. The measurement of crack width is typically done using specialized tools such as crack comparators, crack gauges, or digital imaging techniques. The acceptable Rissweite is often stipulated in building codes and standards, with stricter limits imposed for structures exposed to aggressive environments or those with high aesthetic requirements. Factors influencing Rissweite include the type of loading, material properties, environmental conditions, and the presence of reinforcement. Excessive Rissweiten can lead to ingress of water, aggressive chemicals, and de-icing salts, which can accelerate corrosion of reinforcing steel and lead to further material degradation. Therefore, monitoring and controlling Rissweiten is an important aspect of structural health monitoring and maintenance.
