Unfortunately the article above confuses lightweight aggregate concrete for aerated autoclaved concrete (AAC). AAC is not used to precast structures nor is it moisture cured using pre-wetted …

Due to their porous nature, lightweight aggregates have been shown to exhibit thermal properties that are advantageous when used in building materials such as lightweight concrete, grout, mortar, and concrete masonry units. Limited data exist on the thermal properties of materials that incorporate lightweight aggregate where the pore …

Product Information Lightweight Aggregate Overview Lightweight is an extruded, expanded clay product. Light in nature (25% lighter than stone aggregate), it is often used in high-rises, parking decks, or other …

The less weight of light weight concrete is due to the usage of fine and course lightweight aggregate. When the complete aggregate is replaced with lightweight aggregate, the weight decreases the concrete density of by approx. 10 kilogram per cubic meter. For Example, 1 square foot of 1.5-inch thick normal concrete weighs about 18 pounds.
