Building aggregate is added to concrete and cement mixes to reinforce compounds in building projects. Materials like crushed stone, gravel, sand, and slag are commonly used, and recycled materials like crushed concrete can also be used. The type of aggregate used depends on factors like the pressure the construction must withstand, the desired texture, and local building codes. Building professionals can recommend the ideal choice for any project, and aggregate can also be used for other applications like creating a foundation for railway tracks.
“Building aggregate” is a term used to describe materials that are added to concrete and cement mixes as a means of reinforcing compounds for use in different types of building projects. There are several types of materials or particulates commonly used, including crushed stone, gravel, sand and slag. In recent times, recyclable materials such as crushed fragments of older concrete have been used as building aggregate.
A number of different strategies are used in generating building aggregates for use in various projects. One approach is to mine natural resources to collect stones that can be pulverized or crushed, as well as to collect sand. Recycling street metal is another option, as is using the metal slag left over from various buildings and other types of businesses. Reclaimed concrete from building demolitions can also be crushed and used as aggregate in new construction projects.
While all forms of construction aggregate add strength and durability to the concrete used in the construction of sidewalks, walls, and even block for use in construction projects, the type of aggregate used will vary. Factors such as the degree of pressure the construction must withstand, the desired texture of the finished product, and even the climate during different seasons will all have an impact on the selection of particulate matter used for a given project. In some cases, local building codes will require the use of specific aggregates with certain types of construction, based on local weather conditions and other relevant criteria.
The selection of a particular construction aggregate or particulate often depends on the type of construction project involved. If the construction involves allowing the finished product to be permeable in any way, a rather coarse aggregate is likely to be used. When the goal is to produce a finer texture throughout the concrete, finely crushed stones or even pulverized sand are likely to be the medium of choice. Building professionals are usually familiar with what types of aggregate work best with specific applications and can recommend the ideal choice for any project.
Building aggregate can also be used in applications that do not involve mixing the product with concrete. For example, some forms of aggregate can be used to create a solid foundation for laying railway tracks or to stabilize an area of land for the purpose of pouring a building foundation. The choice of aggregate will depend on the application and the specific circumstances surrounding the construction project.
