Fine aggregate; Coarse aggregate; Fine Aggregate When the aggregate is sieved through a 4.75mm sieve, the aggregate passed through it called fine aggregate. Natural sand is generally used as fine aggregate, silt and clay also come under this category. The soft deposit consisting of sand, silt, and clay is termed as loam.

The aggregates are broadly classified into two types based on the size, namely- fine aggregate and coarse aggregate. In this article, we discuss the properties of the standard aggregates used in the production of concrete …
Coarse aggregate is a term used to describe the larger-sized particles that form the bulk of concrete mixes. These particles are typically greater than 4.75 mm (0.187 inches) in diameter. Coarse aggregates are obtained from natural sources, such as quarries, or can be manufactured by crushing rocks or recycling concrete waste. ... and density ...
— The compacted bulk density of the coarse aggregate with six different proportions is listed in Table 5. When crushed aggregate 1 constitutes 20% of the total coarse aggregate, the maximum compacted bulk density of the coarse aggregate mixture (1532 kg/m 3) is obtained. Thus, the optimal proportion of the coarse aggregate is 20% …

Bulk Density Defined: Bulk density, or unit weight, signifies the weight per unit volume of an aggregate. It is essentially the mass per unit volume or density of the material. Meanwhile, voids in the unit volume refer to the spaces between particles in an aggregate mass that are not filled with solid minerals. Apparatus Required:

— Indeed, the performance of normal fine aggregate of 0–2 mm on the fresh property of RCA concrete was similar to the use of superplasticizer or additional water into the mixture. In addition, the 28-day compressive strength of mix N-RP was about 23% and 5% more than the N-RW and N-RS mixes, respectively.
Density of 10 mm aggregate is 1,620 kg/m3. Its means 1 cubic metre of 10 mm aggregate weight is 1,620 kg. Now Questions "what is weight of 1 cubic metre of 10 mm aggregate", their answer will be following: Ans. 1,620 Kgs is weight of 1 cubic metre (m3) of 10 mm aggregate. 1 cubic metre 40 mm aggregate weight in kg
— Coarse Aggregate; Fine Aggregate; 1)Coarse Aggregate. When the particles of an aggregate are retained on sieve # 4 (4.75 mm) and do not pass from them are known as coarse aggregates. It includes cobbles, gravels, and boulders. Coarse Aggregate is one of the main components of concrete. This chart shows the sizes of coarse aggregates.
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 …
— The coarse aggregate will have most of its particles remaining in the No. 4 fine sieve with a 4.75 mm (0.1870 in.) opening or in a larger sieve. ... The density of an aggregate can be calculated ...
Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). ... This is achieved by using OD aggregate. Additionally, the bulk density is required for the volume method of mixture proportioning.
