Apr 25, 2019 · Lightweight concrete is a mixture made with lightweight coarse aggregates such as shale, clay, or slate, which give it its characteristic low density. Structural lightweight concrete has an in-place density of 90 to 115 lb/ft³, whereas the density of regular weight concrete ranges from 140 to 150 lb/ft³. This makes lightweight concrete ideal ...
Lightweight concrete is a specialized concrete mixture made with lightweight coarse aggregates, and sometimes lightweight fine aggregates, instead of traditional aggregates. This type of concrete possesses an in-place density (unit weight) typically ranging from 90 to 115 lb/ft³ (1440 to 1840 kg ...

Jun 29, 2020 · Lightweight concrete aggregates. The main difference between lightweight concrete and other types of concrete is its composition. Specific types of lightweight aggregates make varying forms of lightweight concrete. These vary from lightweight aggregate concrete, foamed concrete, or Autoclaved Aerated Concrete (AAC).
There are some key considerations you need to keep in mind if you want to make the most out of your lightweight concrete. First and foremost, you need to think about the moisture content. Too much or too little moisture can seriously mess with the strength of your concrete. Secondly, don’t forget to add in some reinforcing fibers.
Apr 3, 2020 · Starting in the 1980s, engineers designed a material — high-performance concrete (HPC) — that did just that. “High-performance concrete developed in the 1980s when people realized that the capillary pores can be reduced in part by reducing the water-to-cement ratio,” says Ulm. “With the addition of certain ingredients as well, this ...
Lightweight Concrete. Definition: concrete of substantially lower density than that made using aggregates of normal density; consists entirely of lightweight aggregate or a combination of lightweight aggregate and normal-density aggregate; its equilibrium densities are generally between 70 and 120 lb/ft3 (1120 and 1920 kg/m3).-.
Feb 5, 2024 · Structural lightweight concrete (SLC) has been a popular building material for over a century, effectively employed to solve weight and durability issues. Industry professionals now recognize SLC as a strong, low-density mixture of cement, water, and various combinations of normalweight aggregates and lightweight aggregates.
