Abstract: Methods and apparatuses are provided for testing and quantifying structural durability characteristics of bridging materials. Embodiments include sieving bridging materials to create uniform batches having particles within a predefined range. Embodiments further include selecting a batch and drying the batch, separating the dried batch into dry samples, and selecting a test sample having an initial mass. Embodiments include sealing the test sample, a volume of liquid, and a rod in a cylindrical testing cell and rotating the cylindrical testing cell containing the rod such that the rod rolls in relation to an inner wall of the cylindrical testing cell and applies force partially crushing the test sample. Embodiments further include sieving a resulting sample to create a durable sample having particles within the predefined range and drying the durable sample.
