Aggregates comprise around 70% of concrete composition and are presented in two forms: (1) fine and (2) coarse. Fine aggregates are usually made of sand or crushed stone, whereas coarse aggregates can be up to 1.5 inches in diameter. One digs up sand or natural gravel from a lake, river, or seabed and then processes the aggregate.
Aggregate is classified into two general sizes: coarse grained and fine grained. Coarse aggregate is rock retained on a 3/8-inch (#4 U.S. sieve). Fine aggregates pass the 3/8-inch sieve and are retained on a #200 U.S. sieve. 6. Fine Aggregate. Fine aggregate consists of natural sand, manufactured sand, or a combination.
Fine aggregates are usually sand or crushed stone that are less than 9.55mm in diameter. Typically the most common size of aggregate used in construction is 20mm. A larger …

H) Weight of fine aggregate= E x Volume of Fine Aggregate x Specific Gravity of Fine Aggregate x 1000 = 0.693 x 0.46 x 2.517 x 1000 = 802.36 kg/m³. Mix Proportion by …
fine aggregate loosely in the mold, filling it until overflowing occurs, and heaping additional material above the top of the mold. Lightly tamp the fine aggregate into the mold with 25 light drops of the tamper. Each drop should start about 0.2 inch above the top surface of the fine aggregate.

Crusher dust is a fine material formed during the process of comminution of rock into crushed stone or crushed sand. This dust is composed by particles which pass 75 μm BS sieve.
Fine-grained concrete, also known as sand concrete, is defined as the concrete in which the coarse aggregate is replaced by sand or any filler material. The maximum size of fine aggregates used in fine-grained …
Sand is a commonly used construction material that is used as a fine aggregate in concrete and mortar. The density of sand can vary depending on its composition and moisture content but typically ranges from 1,400 to 1,600 kg/m³ or 1.4 to 1.6 g/cm³.
Fine gravel sand, also commonly known as fine aggregate, consists of small granules that typically range in size from 0.075 mm to 4.75 mm. It is finer than …

Fine aggregate – Is a natural sand kind that has been sieved and washed to remove particles that are larger than 5 mm; Coarse aggregate – Is gravel that has been crushed, washed, and sieved so that the particles from 5 to 50 mm in size are removed. The coarse and fine aggregate is delivered separately.
Concrete aggregates are composed of geological materials such as gravel, sand and crushed rock. The size of the particles determines whether it is a coarse aggregate (e.g. gravel) or a fine aggregate (e.g. sand). The resulting concrete can be used in its natural state or crushed, according to its use and application.
Definition of Fine Aggregate. Fine aggregate is the essential ingredient in concrete that consists of natural sand or crushed stone. The quality and fine aggregate density strongly influence the hardened properties of the concrete. The concrete or mortar mixture can be made more durable, stronger and cheaper if you made the selection of …
Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness modulus. Fine aggregate means the aggregate which ...
The sand equivalent test (Figure 1) is a rapid field test to show the relative proportions of fine dust or clay-like materials in fine aggregate (or granular soils). The term "sand equivalent" expresses the concept that most fine aggregates are mixtures of desirable coarse particles (e.g., sand) and generally undesirable clay or plastic ...
Fine-grained concrete, also known as sand concrete, is defined as the concrete in which the coarse aggregate is replaced by sand or any filler material. The maximum size of fine aggregates used in fine-grained concrete is 10 mm. ... As per several studies, the replacement of coarse aggregate with fine sand in concrete reduces the strength by 25 ...
Fine aggregate is on of the major constituents of concrete which can influence concrete mix design substantially. Various factors such as fine aggregate fineness modulus, moisture content, specific gravity, and silt content affect the mix proportions of concrete. ... The overall fineness of sand is given by factor called fineness modulus, and ...
Aggregates less than 4.75 mm in size are called fine aggregates; sand falls under the fine aggregate and crushed stone or metal under the coarse aggregates. Here we will learn about fine aggregates, types of fine aggregates & much more. Introduction to fine aggregates: See more
The sand fineness module (fine aggregate) is an index number describing the mean size of sand particles. By doing sieve analysis with normal sieves, it is measured.. The accumulated percentage kept on each sieve is applied and the sum of the fine aggregate is subdivided by 100. To find the fine aggregate fineness modulus, we require 4.75mm, …
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.
According to ASTM C33, aggregates that are less than 4.75 mm are designated as fine aggregate. For this study, locally available well-graded river sand free from deleterious materials used as a fine aggregate. Various tests were performed to investigate the quality of the fine aggregate as per the ASTM standard. Figure 2 shows …
Crushed stone sand is a type of fine aggregate that is produced by crushing granite, limestone, or basalt. This type of sand is commonly used in the construction of pavements, bridges, and buildings. The particles in crushed stone sand are angular, which helps to improve the strength and durability of the concrete and mortar mixes.
Fine aggregate is basically any normal sand particle that comes from the land through the mining process. Fine aggregates comprise regular sand or any squashed stone particles that are 1/4″ or smaller. This item is frequently alluded to as 1/4″ short as it alludes to the size, or evaluation, of this specific aggregate.
