![]() To determine the specific gravity and absorption of coarse aggregate, the following tools are needed: Needed Equipment and Materials Tools for ASTM C128 (Specific Gravity and Absorption of Fine Aggregate) The ratio of the aggregate particle density to the water density is another way to state it. Relative density, also known as specific gravity or the absolute volume of the aggregate, is the ratio of the mass of an aggregate to the mass of a volume of water equal to the volume of the aggregate particles. What is relative density or specific gravity? In addition, the purpose of ASTM C128 is to find the absorption of fine aggregate, where absorption is the process by which water is drawn into and tends to fill the permeable pores in a porous solid body. The aim of “Standard Test Method for Relative Density (Specific Gravity) and Absorption of Fine Aggregate” is to determine the bulk and apparent specific gravities of fine aggregate, which provide an indication of the quality of aggregates.ĭistinction is made between the bulk density of aggregates, which takes into account the volume of voids between aggregate particles, and the density of aggregate particles, as measured by Test Method C29/C29M. In this article, we discuss the methodology and test procedure described in ASTM C128 to conduct the experiment related to the specific gravity and absorption of fine aggregate.
