Rubblettes

Rubblettes are a type of concrete aggregate created from the crushing and screening of waste concrete, brick, and other suitable demolition materials. This material is often referred to as recycled concrete aggregate (RCA) or crushed concrete. Rubblettes are typically produced by demolition contractors and aggregate suppliers as a sustainable alternative to virgin aggregates, such as crushed stone or gravel.

The process of creating rubblettes involves breaking down demolished concrete and masonry into smaller pieces. These pieces are then sorted and screened to remove contaminants like wood, plastic, and metal. The remaining material is crushed to specific sizes to create different grades of rubblettes suitable for various applications.

Rubblettes find application in several construction areas. They are commonly used as a base or sub-base material for roads, pavements, and building foundations. Their load-bearing capacity and drainage properties make them a cost-effective and environmentally friendly choice for these purposes. They can also be incorporated into new concrete mixes, reducing the demand for quarried aggregates and diverting waste from landfills. The use of rubblettes contributes to a more circular economy in the construction industry.
