unit weight of aggregate

METHOD OF TEST FOR UNIT WEIGHT OF AGGREGATE

weight of the aggregate required to fill the measure. (5) Repeat the above steps until a total of three weight determinations are obtained, which do not differ by more than 1 %. F. CALCULATIONS. 1.Calculate the average net weight of aggregate required to fill the measure. 2.Calculate the unit weight of the aggregate from the following formula:

2. Normal Weight Aggregate: Produces concrete with unit loads ranging from 23 to 26 kN / m3 with a specific gravity between 2.5 and 2.7. It has crushing strength at 28 days between 15 to 40 MPa. Commonly used aggregates i.e. sand and gravel; crushed rocks such as granite, basalt, quartz, sandstone and limestone. 3. Heavy Weight Aggregate:

Density of Aggregate Bulk and Relative Density Civil

If the volume is unit then, Bulk Density= Mass. Unit in kg/m 3 or lb/ft 3. In this definition, the volume is that contains both the aggregates and the voids between aggregates particles. The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m 3

Aggregate Base Density Data Earthwork/grading

Jun 09, 2005· Several sources state that "most natural" aggregates have particle densities between 150 and 181 (lb/ft^3). In the Civil Engineering Reference Manual (CERM), under chapter 48, "Properties of Concrete and Reinforcing Steel" Pg. 48-2, "Aggregate" states that, "Most sand and rock aggregate has a specific weight of approximately 165 (lb/ft^3).

Classification of Aggregates

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.

Concrete Aggregates: Effects and Classification Civil

Normal-weight aggregate: An aggregate with a unit weight of 1520–1680 kg/m3 is classified as normal-weight aggregate. Sand, gravel, and crushed rock belong to this category and are most widely used. Concrete made with this type of aggregate has a bulk density of 2300–2400 kg/m3. It is the main concrete used to produce important structural
