-correct amounts of IV fluids is determined using weight and not volume so the specific gravity of each fluid to be added needs to be programmed into the machine-data for most commonly used fluids is available in literature however in the case of some uncommon fluid the specific gravity has to be determined

The specific gravity stands for a dimensionless unit that defines the ratio of density of a substance to the density of water The density of water is 1000 kg/cubic meters at 4 Celsius In physics the weight of the substance differs from its mass The weight is the gravitational force that pulls any object to Earth

1 SPECIFIC GRAVITY AND ABSORPTION OF FINE AGGREGATES AASHTO T 84 GLOSSARY Absorption: The increase in mass due to water in the pores of the material Bulk Specific Gravity (also known as Bulk Dry Specific Gravity): The ratio of the weight in air of a unit volume of aggregate at a stated temperature to the weight in air of an equal volume

Following table shows unit weight of materials used at construction site Please note this is for reference purpose only and may vary from place and type of material We are thankful to Engineer Ravi Verma for submitting this very useful information to us If you also have any other formula and shortcuts which can be used on construction site

Structural Lightweight Aggregate All Rocks Are Not Created Equal: A Case Study of SLWA in Geotechnical Engineered Applications Imani Brodie Surratt E I Carolina Stalite Company About Stalite • Founded in 1961 in Salisbury NC • Manufacturing plant in Gold Hill NC • 700k tons of SLWA produced in 2016 • Largest facility in the world

FINE AGGREGATE SPECIFIC GRAVITY WORKSHEET North Dakota Department of Transportation Materials and Research SFN 2199 (7-2019) Pit Location Laboratory Number Owner Project Number Sampled From PCN Type of Material Submitted By Date Received Weight of oven dry sample grams (A) Weight of saturated surface dry sample in air 500 0

Density of concrete depends on the density of materials used water content while placing voids in the mix how good your placing and compaction is etc Normally this is between 2 35 to 2 5 tons per cum unless light weight air entrained etc

SPECIFIC GRAVITY OF COARSE AGGREGATE AASHTO T 85

Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water Water at a temperature of 73 4F (23C) has a specific gravity of 1 Specific Gravity is important for several reasons Some deleterious particles are lighter than the good aggregates

The coarse aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a coarse aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water It is similar in nature to the fine aggregate specific gravity test

EXPANDED SHALE CLAY AND SLATE LIGHTWEIGHT AGGREGATE GEOTECHNICAL FILL Jody Wall PE Reid Castrodale PhD PE Carolina Stalite Company Salisbury NC 2 2 Normal Weight Aggregate Relative density for rotary kiln expanded lightweight aggregates – Uniformity of specific gravity – Optimal gradation

identification of stone The specific gravity of aggregates ranges from 2 5 to 3 0 Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water Water at a temperature of 73 4'C (23'C) has specific gravity Specify gravity is important for several reasons

Oct 01 2016Specific Surface of Aggregate The surface area per unit weight of the material is termed as specific surface This is an indirect measure of the aggregate grading Specific surface increases with the reduction in the size of aggregate particle The specific surface area of the fine aggregate is very much more than that of coarse aggregate

1 2 This method determines (after 15h in water) the bulk specific gravity and the apparent specific gravity the bulk specific gravity on the basis of weight of saturated surfacedry - aggregate andthe absorption as defined in AASHTO M 132 1 3 The values stated i n SI units are to beregarded as the standard

SPECIFIC GRAVITY AND ABSORPTION OF COARSE AGGREGATE FOP FOR AASHTO T 85 Scope This procedure covers the determination of specific gravity and absorption of coarse aggregate in accordance with AASHTO T 85-10 Specific gravity may be expressed as bulk B = SSD mass and C = weight in water Bulk specific gravity

5 9 5 Bulk Specific Gravity 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) Bulk specific gravity of aggregate is important

The coarse aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a coarse aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water It is similar in nature to the fine aggregate specific
