Bulk specific gravity is involved in most key mix design calculations including air voids, VMA and, indirectly, VFA. Correct and accurate bulk specific gravity determinations are vital to proper mix design.
Jul 30, 2024 · Bulk Specific Gravity (BSG) is crucial in affecting material density and mix design calculations for engineering applications. This blog post explores BSG’s importance, how to measure it, factors influencing it, and its applications in engineering.
The bulk specific gravity is the ratio of the weight of a given volume of aggregate, including the permeable and impermeable voids in the particles, to the weight of an equal volume of water ( Kandhal et al., 2000; Prowell and Baker, 2004; Sholar et al., 2005 ).
Aug 5, 2024 · Enter the SSD Weight, Weight in Water, and Bulk Specific Gravity to calculate the Oven Dry Weight. The advanced version of this calculator allows you to calculate the Adjusted Bulk Specific Gravity by incorporating the Total Dry Weight, Apparent Specific Gravity, and Absorption percentage.
The bulk specific gravity (SSD) is defined as the ratio of the SSD mass of the particles to the mass of a volume of water equal to the gross volume of the particles (i.e., the volume including the permeable pores), so.
Summary. The mass of a coarse aggregate sample is determine in SSD, oven-dry and submerged states. These values are then used to calculate bulk specific gravity, bulk SSD specific gravity, apparent specific gravity and absorption. Figure 5 shows major coarse aggregate specific gravity equipment.
• Apparent Specific Gravity - Gsa A / (A - C) • Bulk Specific Gravity - Gsb A / (B - C) • Absorption, % (B - A) / A Coarse Aggregate Specific Gravity Calculations - Example Problem
Aug 15, 2024 · To calculate the Bulk Specific Gravity (GSB), the formula is: \ [ GSB = \frac {DW} {SSD - WW} \] where: \ (GSB\) is the Bulk Specific Gravity, \ (DW\) is the oven dry weight in grams, \ (SSD\) is the saturated surface dry (SSD) weight in grams, \ (WW\) is the weight in water in grams.
Feb 1, 2024 · The formula for calculating bulk specific gravity (GSB) is as follows: Example Solve. Suppose we have an aggregate with a mass of 2000 grams and displaces 500 milliliters of water. Using the formula mentioned above: Thus, the bulk specific gravity (GSB) of the aggregate is 4. FAQ’s. Q: What is bulk specific gravity (GSB)?
AASHTO M 132 and ASTM E 12 define specific gravity as: “…the ratio of the mass of a unit volume of a material at a stated temperature to the mass of the same volume of gas-free distilled water at a stated temperature.” The commonly used “stated temperature” is 23° C (73.4° F).
