WebGradation. The four aggregates were tested for particle size and gradation by the wet sieve analysis ASTM C-117-67. The wet sieve analysis was used for an accurate account of dust and agglomerations of fines that may be found in highly textured kiln fired aggre gates. The gradation test data for these four aggregates are included in Table 1. WebThe grading of the different sizes of the fine aggregate falls within the upper and lower limits specified by ASTM C33/C33M -13 [6]. Therefore, the fine aggregate was well graded.
Web22 Jun 2024 · Coarse aggregate is a term used in construction to describe a type of material that is commonly used in the production of concrete. It is typically made up of various materials such as gravel, crushed stone, and recycled concrete. The size of the coarse aggregate can vary, but it is typically between 3/8 inch and 1.5 inches in diameter. WebSome lightweight shales (not used in HMA production) can have absorptions approaching 30 percent, while other aggregate types can have near zero absorption. Typically, aggregate used in HMA production will have an absorption between just above zero and 5 percent.
WebThis specification covers lightweight aggregates intended for use in structural concrete in which prime considerations are reducing the density while maintaining the compressive strength of the concrete. Procedures covered in this specification are not intended for job control of concrete.
