Advantages and Disadvantages of Lightweight Concrete ...

Apr 12, 2018· Specific types of lightweight aggregates make varying forms of lightweight concrete. These vary from lightweight aggregate concrete, foamed concrete, or Autoclaved Aerated Concrete (AAC). The aggregates used in AAC are extremely fine, even smaller than a grain of sand. This composition makes AAC highly suitable for precasting and reshaping.

Lightweight Aggregate (LWA) Minergy

Minergy LWA was also used to produce lightweight concrete masonry. Compared to conventional masonry units made with sand and stone, lightweight concrete masonry has higher fire ratings and higher Rvalues. Since lightweight concrete masonry is about 20 percent lighter than conventional masonry, it is easier to install and transport.

Understanding Different Types of Lightweight Concrete

LowDensity Natural Aggregate Concrete. Most lowdensity aggregates are volcanic in origin and include pumice, tuff, scoria, and cinders. Diatomite is also something used as the aggregate component of lightweight concretes. The advantage to these types of aggregate is that they often do not require processing apart from crushing or screening.

Lightweight Aggregates: How Do You Make the Right Decision ...

The use of lightweight aggregates may have an impact on the compressive strength of the concrete. Highly absorptive lightweight aggregate should be wetted at least 24 hours prior to use. It is not recommended that dry lightweight aggregate be directly batched and mixed because the aggregate particles can continue to absorb water from the mix.
