Overview the coarse aggregate angularity (caa) test is a method of determining the angularity of coarse aggregate (figure 1) coarse aggregate angularity is. The weight of polyethylene fibers used as replacement for coarse aggregate is the independent variable of the experiment this was measured through one. There is a general belief that crushed aggregates contribute higher strength in concreting compared to rounded aggregates contrary to this belief, our study. Aggregate is the component of a composite material that resists compressive stress and experiments and mathematical models show that more of a given volume can be filled with hard spheres if it is first filled with large spheres, then the.
