Types of Aggregates: A Comprehensive Guide

Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic cement concrete, or iron blast furnace slag, that is used with a hydraulic cementing medium to produce concrete or mortar. Aggregates are divided into two main categories: coarse-grained and fine aggregates. The aggregate of each type is further subdivided into many types and classified according to its size. The sieve analysis technique is used to determine the gradation of aggregates for use in particular applications and for other purposes. Aggregates are small fragments of rocks or minerals used in construction.

The four main types of aggregates are sand, gravel, crushed stone, and recycled or filled concrete. These materials are used in landscaping projects such as sidewalks, paths, and parking lots to hold ingredients together and harden them. Aggregate categories include gravel, sand, recycled concrete, slag, topsoil, ballast, type 1 MOT, and geosynthetic aggregates (synthetic products commonly used in civil engineering projects to stabilize terrain). MOT type 1 is a stone that meets MOT standards in terms of strength, size and composition for use as a compact subbase. There are also several aggregate suppliers available who can provide material to projects if needed.

Aggregates are used for their economic factor, to reduce cracks and most importantly to provide strength to the structure. Some of the more common types of aggregates include fine aggregates such as sand or crushed stone with a size of less than 9.5 mm in diameter; coarse-grained aggregates such as medium sand, fine sand, silt, clay and fine gravel; medium gravel; coarse-grained gravel; pebbles; cobblestones; and rocks. The properties of aggregates depend on the bedrock which can be igneous, sedimentary or metamorphic. For all your garden and construction needs contact Grabco and learn about all the different types of aggregates they offer. The use of the largest permissible maximum size of coarse-grained aggregates reduces cement and water requirements. All kinds of aggregate made from igneous rock, granite rock, sedimentary rock and metamorphic rock can be used for different purposes in the construction of pavements, roads, streets and buildings as well as interior and exterior design of homes.

Ready Mix Concrete Essex is a mixture of cement, aggregate, sand and water that forms solid materials suitable for road building or pavement construction. Once processed, aggregates should be handled and stored properly to minimize segregation and degradation and prevent contamination.
