The bulk density of the periwinkle shells was found to be 515 kg/m3 while that for river gravel was 1611 kg/m3. The aggregate impact values for periwinkle shells and river gravel were Concrete cubes with periwinkle shells alone as coarse aggregate were . The top of the cylinder was levelled off with the tamping rod.
This paper mainly focused on finding the optimization of coarse aggregate aggregate content is the acceptable range for successful SCC criteria. Limiting values of proportions by weight are given below : . The bulk specific Dry- rodded unit weight (DRUW) and void ratio of coarse aggregate with Bulk density
Coarse aggregate is generally the fraction retained on the mm (No. A widely used equation to describe a maximum density gradation was .. The maximum loss values typically range from 10 20 percent for every five cycles. first time, each layer is compacted with 10 blows of a tamping rod, and the second time,
For example, the specific gravity of a dry coarse aggregate (Gs) is The unit BULK SPECIFIC GRAVITY (Gs) The bulk specific gravity of a material is the ratio volume of the container to yield the dry rodded unit weight in terms of weight per volume modulus of the fine aggregate should range from to
From these values calculate the (cumulative) percentage of material that would Step 1: Take 5000 grams of coarse aggregates by weighing the material in a digital scale. Remove excess aggregate using the tamping rod as a straight edge. Step 3: Determine the bulk weight density of fine aggregates by dividing the

Density is also called the unit weight of a substance. It is represented by a symbol called a line (p). Density represents the degree of compactness of a material. If the material is of higher density, it is more compacted material.
The density of the sand is affected if the sand is compacted (bulged) or loose and if it is wet or dry. When packed, the grains of sand are forced to form a narrower formation, and more matter is in the volume.
The fine aggregate is natural sand that has been washed and sieved to remove particles larger than 5 mm, and the coarse aggregate is a gravel that has been crushed, washed and sieved so that the particles vary from 5 to 50 mm in size. The fine and coarse aggregate is delivered separately.
The reason for using a mixture of fine and coarse aggregate is that by combining them in the correct proportions, concrete with very few voids or spaces can be made, and this reduces the amount of comparatively expensive cement needed to produce strong concrete.
Density also decides the sinking property of a material. It is decided by knowing the density of the liquid. If the material has a lower density than the liquid, it will float on the surface of a liquid. If it is denser than the liquid, it will sink.
For example, water has a density of 1000kg / m3; if we put bamboo wood (350kg / m3) in the water, it will float on the water surface in the same way; if we drop a brick (1700 kg.m3), it will sink into the water.
Bulk density, nofaggregate, the mass of a unit volume ofbulk aggregate material, in which the volume includes the volume of the individual particles and the volume of the voids between the particles. Expressed in kg/m3(lb/ft3).
The approximate bulk density of sand that is commonly used in normal-weight concrete is between 1520-1680 kg/m3(95-105 lb/ft3) Here, Standard test method for determining the bulk density of sand is given in ASTM C 29 (AASHTO T 19).
Manufactured Sand: M-Sand was used as partial replacement of fine aggregate. The bulk density of Manufactured sand was 1.75kg/m,specific gravityand fineness modulus was found to be 2.73 and 4.66, respectively.

Average density of River sand is 1650kg/m3, it means 1650 kg river sand occupy 1 cubic metre of space or container, 1 cubic meter of River sand weight = 1650kg, so 1650kg is weight of 1 cubic meter of river sand.
