The history of lightweight aggregates is the subject of another section. This discussion includes the development used by the Romans to construct the Coliseum (about AD 80) and the Pantheon (about AD ). The various types of lightweight aggregates produced in the United Kingdom, their manufacture, properties and applications are described. Note: Citations are based on reference standards.

Lightweight aggregate is a type of coarse aggregate that is used in the production of lightweight concrete products such as concrete block, structural concrete, and pavement. The Standard Industrial Classification (SIC) code for lightweight aggregate manufacturing is ; there currently is no Source Classification Code (SCC) for the industry. What is Lightweight Concrete? Lightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates. Structural lightweight concrete has an in-place density (unit weight) on the order of 90 to lb / .

Commercial Aggregates--Lightweight in Dallas, GA | The Blue Book Building and Construction Network. Lightweight concrete is typically manufactured with combinations of normalweight and lightweight aggregates. Using all coarse and fine lightweight aggregates in a concrete mixture can decrease the concrete density to less than 90 lb/ft3 3( kg/m). Structural . Lightweight aggregate(sometimes is called as low density aggregate) is a generic name of a group of aggregates for structural concrete, mortar, or plaster that weighs. This specification covers lightweight aggregates intended for use in structural concrete in which prime considerations are reducing the density while maintaining the compressive strength of the concrete. Procedures covered in this specification are not intended for job control of concrete.
Our lightweight aggregates from Lytag® are made from fly ash generated by coal fired power stations. Our technology heats the fly ash to 1,°C to create a hard pellet, with a honeycombed internal structure. Which can then be used as a superior, lightweight aggregate which is up to 50% lighter than natural 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 aggregates. Aggregates are the most mined materials in the world. Lightweight aggregates for concrete [Forrest Theodore Moyer] on hisn-alarum.com *FREE* shipping on qualifying offers. The use of lightweight aggregates can be very beneficial and cost effective. However, when producing concrete using lightweight aggregates, there are several things you should be aware of. Fluctuations in the gradation, specific gravity, absorption, and moisture content are of particular concern.
