The AD and wet states represent the variable moisture contents that will exist in stockpiled aggregates. The SSD state is the best choice as a reference state for the following reasons: It represents the "equilibrium moisture" state of the aggregate in concrete; that is, the aggregate will neither absorb water nor give up water to the paste.

HBM (Hydraulically Bound Material) is the generic name for a family of products, these include: Cement Bound Granular Material (CBGM) (BSEN 14227-1). CBGM is used in road, airfield, port, and other heavy-duty pavement construction projects. It is affordable and a great sustainable alternative to asphalt construction.
🕑 Reading time: 1 minuteProportioning of concrete is the process of selecting quantity of cement, sand, coarse aggregate and water in concrete to obtain desired strength and quality. The proportions of coarse aggregate, cement and water should be such that the resulting concrete has the following properties: When concrete is fresh, it should have enough workability […]
Medium workable concrete is useful for nearly all construction work. This type of concrete allows simplicity in mixing, transportation, placing, and compaction without losing homogeneity. This concrete doesn't show much segregation. The compaction factor of such concrete is about 0.92, and the water-cement ratio is 0.4 to 0.55.
The Recycled aggregates properties may be different accordingly types of concrete because the parent concrete was designed for its purposes such as permeable, durable and high strength concrete. Aggregate recycling is a simple process there is no complex method involved.

For the BGO concrete line, the choice fell on two LINEMIX 3500 ST stationary concrete mixing plants installed in parallel, while the aggregate side is based on the LINEMIX ST 5760 stationary SBM aggregate store. Both plant lines were precisely adapted to the customer's requirements.
aggregate, in building and construction, material used for mixing with cement, bitumen, lime, gypsum, or other adhesive to form concrete or mortar.The aggregate gives volume, stability, resistance to wear or erosion, and other desired physical properties to the finished product. Commonly used aggregates include sand, crushed or broken stone, gravel (pebbles), broken blast-furnace slag, boiler ...

SBM Mineral Processing has erected a high-performance stationary concrete mixing plant with two self-sufficient production lines and connected 6000 m³ high-silo storage for primary and secondary aggregates in an installation time of just under ten months.. The recycling centre for building rubble and mineral residues sits on a 3.6- hectare site with its own railway siding.
SBM is specialized in manufacturing crushing plants for aggregate such as jaw crusher, impact crusher, cone crusher etc. the newly designed sand making machine is a professional machine applied in producing artificial sand and manufactured aggregate.
Unlike concrete based on natural aggregates, recycled-aggregate concrete contains two types of cement paste: the "new" paste creating concrete strength and the "old" paste whose parameters – such as its composition, water/cement ratio and degree of carbonation – are unknown. In addition, such concretes contain the "old" aggregates whose origin and properties are usually unknown ...

Concrete production equipment becomes more sophisticated. Depending on what it is used for, the material, with its basic ingredients of aggregates, cement and water, can be blended into any amount of mixes with a variety of strengths and different densities. As the use of concrete has developed so too has the equipment used in its production ...
Aggregates. For a good concrete mix aggregates need to be clean hard strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete Aggregates which account for 60 to 75 percent of the total volume of concrete are divided into two distinct categoriesfine and coarse.

Exposed Aggregate Concrete: exposed aggregate gives you all the strength, durability and ease of maintenance that concrete gives while adding a textural element by exposing the aggregate. This is a very popular option for driveways as it has the added benefit of hiding stains due to its pebbled aesthetic and looks incredible.
Construction aggregate, or simply aggregate, is a broad category of coarse- to medium-grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates.Aggregates are the most mined materials in the world. Aggregates are a component of composite materials such as concrete and asphalt; the aggregate serves as ...
1 ACI Concrete Terminology A/F ratio — the molar or mass ratio of aluminum oxide (Al 2O 3) to iron oxide (Fe 2O 3), as in portland cement. Abrams' law — a rule stating that, with given concrete materials and conditions of test, the ratio of the amount of water to the amount of the cement in the mixture
The effect of using recycled concrete aggregates (RCA) on the basic properties of normal concrete is studied. First, recycled aggregate properties have been determined and compared to those of normal aggregates. Except for absorption, there was not a significant difference between the two. Later, recycled aggregates were introduced in concrete mixes. In these mixes, natural coarse aggregate ...

Aggregates. Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the ...
Aggregate serves as a reinforcement to add strength to composite materials such as concrete. Aggregates can be categorized into three groups: fine aggregate, coarse aggregate, or all-in aggregate. Fine aggregate, such as concrete or masonry sand is defined as material that mostly passes through a 4.75 mm IS sieve.
