Abstract:
The presence of cracks in concrete is a concern because they can reduce the mechanical properties and durability of concrete. The presence of a single crack in concrete and its effect on strength and durability has been studied extensively, but the influence of multiple small cracks or microcracking density as it relates to serviceability is not as well understood. An experimental study was conducted to quantify the relationship between cracking parameters (width, depth, and density) and the strength, stiffness, and durability of concrete. It was found that the density of microcracks is an important factor to take into account for durability, as it can impact serviceability.
