... materials in the concrete confirms the use of beach sand in the concrete mix. Unwashed beach sand was considered earlier to be the source of significant residual levels of salt in the original concrete. The composition of the original concrete included a high amount of cryptocrystalline silica, some...

... on a hard substrate abrade the polymer surface. In third-body abrasive wear, hard particles, such as silica (sand), plow through the polymer surface, removing material as it scrapes across the surface. Third-body abrasive debris can be generated in a two-body sliding system if the polymer scratches a harder...

... rate of carbon fiber–reinforced polyetherimide (CF/PEI) has been investigated using silica sand particles (200 ± 50 μm) at different impact angles and speeds. The study was conducted to compare the wear behavior of neat PEI and unidirectional CF/PEI ( Ref 29 ). It was observed that higher wear...
