Astm C128 Specific Gravity And Absorption Of Fine Aggregate Pdf __hot__ Jun 2026

Fine aggregate’s specific gravity and absorption directly affect concrete mix design, workability, and strength. ASTM C128 provides a pycnometer method to measure:

ASTM C128 was successfully performed. The fine aggregate tested meets typical concrete aggregate requirements. Specific gravity values are necessary for absolute volume calculations in mix design.

is the ratio of the mass of a unit volume of material to the mass of an equal volume of water. ASTM C128 defines three types:

ASTM C128 prescribes strict formulas based on the masses obtained.

Specific gravity is the ratio of the density of an aggregate to the density of water. In the context of ASTM C128, there are three primary types of specific gravity calculated:
