The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m 3 (75-110 lb/ft 3). Here, the Standard test method for determining the bulk density of aggregates is given in ASTM C 29 (AASHTO T 19).

Solid density: The solid density is obtained by grinding rocks into small particles to exclude impermeable voids and then measuring the density of the small particles in a similar way as fine aggregate. (2) Bulk density: The bulk density is the ratio of the weight of rock over the bulk volume which includes the permeable voids. (3)

This test method covers the determination of bulk density ("unit weight") of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size.

Aggregates with a bulk density of less than 70 lb/ft 3 are classified as lightweight, while those with a density exceeding 130 ft 3 are considered heavyweight. The bulk density of aggregate particles is influenced by their size distribution; although aggregates of a single size can only be compacted to a limited degree, introducing smaller ...

Bulk Density: The bulk density of aggregate is determined by measuring the mass of the aggregate per unit volume, including the voids between particles. This is done by filling a container of known volume with …

The bulk density of aggregates used in normal-weight concrete is typically in the range of 1200 kg/m 3 to 1750 kg /m 3; for lightweight concrete mixes it is typically in the range of 560 kg /m 3 to 1120 kg /m 3; and for heavyweight concrete the bulk densities are typically more than 2100 kg /m 3 . The specific gravity and quantity of aggregate ...

3. Relative Density (Specific Gravity) of Aggregate. Relative density, often called specific gravity, is a ratio that compares the mass of an aggregate to the mass of an equal volume of water.This ratio helps determine how much heavier (or lighter) the aggregate is …

The unit weight is then obtained by dividing the bulk density by the volume of the aggregate. The unit weight of 12mm aggregate is an important factor in the design of concrete mixtures. It is used to calculate the amount of fine and coarse aggregates needed in a specific concrete mix, which directly affects the strength and durability of the ...

Bulk density refers to the weight of the aggregate per unit volume, while specific gravity is the ratio of the density of the aggregate to the density of water. The voids of an aggregate refer to the space between the particles and …

After that, weight the aggregate mass that is inside the container and divide it by the volume of container. This will give you the bulk density of the loose aggregates. Compacted Bulk Density. Compacted bulk density can be determined by filling the container in three layers and tamped each layer with a 16mm diameter rounded nosed rod.

G = Specific gravity of the aggregate. ϒ = Bulk density in kg/litre. Result. The bulk density is reported in kg/litre to the nearest 0.01 kg. The percentage of voids is reported to the nearest whole number. Mention whether the aggregate is (a) oven dry, (b) saturated and surface dry or (c) with a given percentage of moisture. Share this:

In addition, different bulk density values can cause different aggregate distributions of soil blocks. Because of the close relationship between the mechanical characteristics of soil blocks and aggregates, increasing bulk density (by increasing the number of aggregates in each unit volume of soil) may affect the soil blocks' strength.

Bulk density and % voids are important properties of coarse aggregates used in the field of civil engineering. These properties determine the quality and suitability of aggregates for use in …

This article will discuss the two main types of density associated with aggregates—Bulk Density and Relative Density—explaining their significance, calculation …

Bulk density of fine aggregates, also known as bulk unit weight, is the weight of the aggregate material in a given volume. It is usually expressed in kilograms per cubic meter (kg/m3) or pounds per cubic foot (lb/ft3). The bulk density is an important parameter in determining the suitability of aggregates for various construction applications.

Determination of unit weight or bulk density and void of aggregates. 1. Balance. 2. Cylindrical metal measure. 3. Tamping rod. Take the required amount of test sample form the bulk sample using any sample reduction method.

Properties of aggregates such as bulk density, specific gravity, voids, water absorption and its values are presented in this article. 1. Aggregates: Bulk Density, Specific …

Classification of Aggregates. The variability in density can be used to produce concrete of widely different unit weights, see Table (1). The most common classification of aggregates on the basis of bulk specific gravity is lightweight, normal-weight, and heavyweight aggregates. This section specifically address the different characteristics ...

The bulk density of normal weight aggregates varies from 1200 to 1750 kg/m 3 that produces concrete of normal density (2200–2400 kg/m 3). Lower density aggregates such as expanded shale, clay and slate are often used to produce lightweight …

The desired density is achieved through high-density aggregates such as iron oxides. Before getting into the process, some considerations will be taken into account, such as intended use, availability, physical and chemical properties, and cost. ... Aggregate Bulk Density, kg/m3 (pcf) Concrete Density kg/m3 (pcf) Fixed-water percent by weight ...

The bulk specific gravity (S) of the aggregate should also be known. Once the bulk density and bulk specific gravity have been determined, Equation 6 can be used to calculate the void content in the aggregate. The equation involves subtracting the bulk density (M) of the aggregate from the product of the bulk specific gravity (S) and the ...

In normal weight concrete, commonl y, the approximate bulk density of aggregate is between 1200-1750 kg/m 3. Aggregates with bulk d ensities less than 1120 kg/m 3 are called lightweight while aggregates weighing more than 2080 kg/ m 3 are regarded heavyweight.

Value of the bulk density of the aggregate depends upon the amount of effort used to fill the container as densely as possible, size distribution, shape and specific gravity. More graded the aggregate, greater is the bulk density. …

The bulk density of aggregates indicates the mass of aggregates within a unit volume, including the void spaces existing among them. It is generally ...

The bulk density or unit weight of an aggregate is defined as the mass of the aggregate per unit volume. it is expressed in kg/liter. What is the value of Coarse Aggregate Density? Most of the aggregates possess a …

There are two main measurements for calculating the density of aggregates for building professionals: bulk density and relative density. 1. Bulk Density. Bulk density, also known as apparent density, calculates the mass of the aggregate material per unit volume. The bulk density measurement includes the particles and also the empty spaces ...
