CONSTRUCTION AGGREGATE Meaning and
Definition
-
Construction aggregate refers to a category of coarse particulate materials that are used in the construction industry. These materials are commonly combined with cement or bitumen to provide bulk and stability to the final construction product. Construction aggregates are derived from various natural sources, including quarries, rivers, and crushed stone deposits.
The primary purpose of construction aggregates is to enhance the structural integrity of buildings and infrastructure projects. They are widely employed in the construction of roads, bridges, dams, airports, and other civil engineering works. Typically, construction aggregates are graded by size, ranging from fine particles like sand to larger gravel and crushed stone materials.
Construction aggregates play a crucial role in providing the necessary bulk and strength needed to support heavy loads and withstand compressive forces. This is achieved through the interlocking nature of the particles, which enhances the stability and durability of the construction material. Aggregates also improve the workability of concrete and asphalt mixtures, ensuring uniform distribution and reducing the amount of cement or asphalt required.
Due to their wide availability and cost-effectiveness, construction aggregates are extensively used worldwide. They are essential for constructing strong and durable structures, while also contributing to the overall economy and infrastructure development of a country. As a versatile material with various applications, construction aggregates are a fundamental component of the construction industry.
Etymology of CONSTRUCTION AGGREGATE
The word "construction" comes from the Latin word "construere", which means "to pile up" or "to build". It is derived from the combination of the prefix "con-" meaning "together" and "struere" meaning "to build" or "to arrange".
The word "aggregate" comes from the Latin word "aggregatus", which is the past participle of "aggregare", meaning "to add to" or "to gather". It is derived from the combination of the prefix "ad-" meaning "to" and "grex" meaning "flock" or "herd".
When these two words are combined, "construction aggregate" refers to a material that is added to the process of building or constructing something, and it is typically produced by gathering or piling up different materials or particles.
