Fine Aggregate Specific Gravity Set includes pycnometer with conical mold and tamper. Pycnometer is 1 qt () threaded glass jar with a rubber gasketed brass top tapered to 3/8 in ( mm) hole at top.

Determine the total mass of pycnometer, specimen, and water. Remove fine aggregate from pycnometer, dry to constant mass at 230 plus or minus 9 degrees Fahrenheit. Determine mass of pycnometer filled to calibration capacity with water at plus or minus 3 degrees Fahrenheit.

The Specific gravity of coarse aggregate was determined as It was 13% reduce from standard value which is in the range from to The Specific gravity of fine aggregate was also accurate. Aggregate Crushing value test: This test was performed as per IS: 2386 (Part IV) 1963. The crushing value of RCA was 20%.

The maximum volume of asphalt which a mix can contain is the volume of the voids in mineral aggregate (VMA) plus the volume of asphalt absorbed into the aggregate. ) may be determined by the following formula: = absorbed asphalt, section = bulk dry specific gravity of the total aggregate, section

Calculations for Fine Aggregate: Obtain: A = weight of ovendry specimen in air, g. B = weight of pycnometer filled with water, g. S = weight of the saturated surfacedry specimen, g. C = weight of pycnometer with specimen and water to calibration mark, g.

Z1 = mass of the pycnometer containing wet sample and water, g. G = saturated surfacedry specific gravity. Y = mass of pycnometer filled with water (calibration), g. Note 2—It is not necessary to weigh out a definite quantity of wet aggregate when the percentage of free moisture is calculated from the formula.

water and fine aggregate together, the sample was spread out on a on a flat nonabsorbent surface and exposed to room temperature air, and was stirred frequently to secure homogeneous drying.

The specific gravity of the soil solids at the test temperature shall be calculated from the density of the soil solids and the density of water at the test temperature or from the mass of the oven dry soil solids; mass of pycnometer, water, and soil solids at the test temperature; and mass of the pycnometer and water at the test temperature.

6. Record the weight of the pycnometer with fine aggregate and water filled to calibration level as "Weight of sample immersed in water" (C), to the nearest g. CALCULATIONS . 1. Calculate bulk specific gravity (saturated surface–dry basis) as follows: Bulk specific gravity (saturated surface–dry basis) = A / (B – C)

Two procedures – bowl and pycnometer / volumetric flask – are covered. The first 11 steps are the same for both. 1. Separate the particles of the sample, taking care not to fracture the mineral particles, so that the particles of the fine aggregate portion are not larger than mm (1/4 in.).

mark, g Remove the fine aggregate from the pycnometer, dry C = mass of pycnometer filled with specimen and water to in the oven to constant mass at a temperature of 110 6 5 °C calibration mark, g (230 6 9 °F), cool in air at room temperature for 1 6 1⁄2 h, and R1= initial reading of water level in Le Chatelier flask, mL determine the mass.

Specific Gravity Absorption of Fine Aggregate Set. The specific gravity set includes the pycnometer jar and conical mold with tamper. Used for the determination of bulk and apparent specific gravity and absorption of fine aggregate. The stainless steel conical mold is 40mm ID at the top, 9mm ID at the bottom, and 75mm high.

Whenever the slab thickness is 150mm, the bar diameter shall be 10mm for normal spacing.(It can be 8mm at very closely spaced). Slab thickness can be 10mm,110mm,120mm,125mm,150mm, etc.

ILLINOIS TEST PROCEDURE 27 SIEVE ANALYSIS OF FINE AND COARSE AGGREGATE Effective Date: March 1, 2013 Revised Date: January 1, 2017 January 1, 2017 Manual of Test Procedures for Materials 34 For all sieves that are considered overloaded and split in more than one increment.

the pycnometer must be reproducible within cm. NOTE 1: The top of the pycnometer must be flat and level. If it is not, grind it flat by rubbing the lip of the pycnometer in a circ ular motion on a piece of emery cloth laid on a flat surface. C. Glass Plate – A flat and level glass plate to be used as a calibration

The fine aggregate angularity test determines the loose uncompacted void content of a fine aggregate material. The void content information derived from this test gives you an indication of the effect fine aggregate will have on stability and voids in the mineral aggregate.

Gravity Flask (Phunque Flask) Key element in a method for conducting specific gravity/absorption determinations for aggregate. H3400Specific Gravity Flask (Le Chatelier) For determining density of powdered materials — limes, slag and hydraulic cement.
