The process using multiple waste streams to manufacture synthetic lightweight aggregate includes providing a mixture of aggregate wash and at least one of another waste stream, such as waste lube oil or sewage sludge The mixture is formed into pellets and subjected to various firing stages and temperatures in which the calcination and subsequent bloating occurs...

Construction aggregate

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 aggregat Aggregates are the most mined materials in the world...

US20040217505A1

The invention provides a simple, energy efficient and direct method of producing synthetic lightweight aggregate, in spheroidal, other regular shapes or even in crushed form, in a wide range of defined sizes and target densities by preparing appropriately batched and mixed slurry mixes of cement, sand, waste materials like fly ash and/or stone dust, additives, water and preformed stable foam ....

Advances in Materials Science and Engineering

In addition, during the production process of RA, mechanical crushing, particle collision, and sliding also produce microcracks in the aggregate, and these will result in an increase in the aggregate porosity and a decrease in the apparent relative density...

Performance assessment of core

The density of cold-bonded lightweight aggregates is significantly higher than that of sintered lightweight aggregat Since the sintering technique consumes an enormous amount of energy and emits a huge amount of pollutants, the implementation of a cold-bonded method, in manufacturing low-density lightweight aggregates, is very important from an economic and environmental perspective...
