![]() The fine and coarse aggregate is delivered separately.Īs they need to be sieved, a prepared mixture of fine and coarse aggregate is more expensive than the natural all-in aggregate. 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 aggregate is an aggregation of non-metallic minerals obtained in the form of particles and can be processed and used in the construction of civil and road engineering.Īggregates Are Mainly Classified into Two Categories: This is compacted sand that is also almost saturated with water.Īlso, read: 10 Best Cement Companies In India Aggregate Density This is the sand that has been in a natural and naturally compressed environment that is now wet. Sand that has been packed manually or mechanically (compacted) It is sand in its undisturbed natural form, where it has been partially compacted by rain and gravity over time, but is now dry It is dry sand that has been moved or agitated to loosen the natural packaging process. The average density of the different sand conditions is as follows: When the sand is wet, the water is in the sand, also affecting the total matter in the volume. This sand has the Fineness modulus of 5.24. locally available River sand having a bulk density of 1.71 kg/m3 was used for the construction (specific gravity is 2.65). When packed, the grains of sand are forced to form a narrower formation, and more matter is in the volume. The density of the sand is affected if the sand is compacted (bulged) or loose and if it is wet or dry. The Density of Sand utility returns sand density based on sand conditions ( wet/dry in bulk / packaged). It is expressed in kg / m 3 or lb / ft 3 and shows the compactness of the construction material. The density of construction materials is their Mass per unit volume of materials. If the material is of higher density, it is more compacted material. Density represents the degree of compactness of a material. It is represented by a symbol called a line (p). Why Is Density Used to Identify a Material?ĭensity is also called the unit weight of a substance.What Is the Importance of Specific Gravity of Fine Aggregate?.What Is the Density of Lightweight Concrete?. ![]()
