2. What is grading of fine aggregate? The grading of fine aggregate refers to the distribution of particle sizes within the aggregate. It is typically expressed in terms of percentages of various particle sizes like sand, silt, and clay, and is an important factor in determining the workability and strength of concrete. 3.

2023年11月22日  Depending upon the particle size, fine aggregates are described as fine, medium and coarse sands. Fine Sand; Fine sand is characterized by its relatively small particle size. Fine sand typically falls within the range of 0.075 to 2 millimetres. It is often sourced from natural deposits such as riverbeds or seashores.
