2024613· It is important to avoid common errors such as incorrect sample amount and underestimating or overestimating tolerances. Determining Sample Size Choosing the right sample size is crucial for accurate test results and obtaining the necessary data for fine and coarse aggregate. For fine aggregate, use a minimum of 300 g.

Due to their characteristics, crushed granite with 20 mm maximum size was the common coarse aggregate referred to as Natural Coarse Aggregates (NCA). Recycled Coarse Aggregates (RCA): RCA has been taken out of waste concrete rubble, washed, and screened to no more than 20 mm. Water uptake was more in RCA (4.5 %) relative to NCA (0.5 %).
