Cellular Concrete is a cementitious paste of neat cement or cement and fine sand with a multitude of micro/macroscopic discrete air cells uniformly distributed throughout the mixture to create a lightweight concrete. It is commonly manufactured by two different methods. Method A, …
A: (Kelly) Lightweight concrete does not necessarily require the use of expensive or unusual additives. It is basically concrete that has replaced the standard heavy gravel aggregate with a lightweight substitute, such as crushed volcanic stone, perlite or vermiculite.
Lightweight concretes can be produced with an over-dry density range of approximately 300 to a maximum of 2000 kg/m 3, with corresponding cube strengths from approximately 1 to over 60 MPa and thermal conductivities of 0.2 to 1.0 W/mK. These values can be compared with those for normal weight concrete of approximately 2100–2500 kg/m 3, 15 to greater than 100. MPa and 1.6–1.9 W/mK.

Lightweight Concrete can be applied on exterior and interior surfaces. The most popular product for interior surfaces is LightWeight Gypsum Concrete (GypCrete). For Exterior surfaces, such as decks, balconies, or roof pads, cement-based Lightweight Concrete is the best choice! – Finish Floor – Slope Control – Long Term Durability – High PSI
Concrete is considered to be lightweight is the density is not more than 2200kg/m 3 (the density of normal weight concrete is assumed to be between 2300kg/m 3 and 2400kg/m 3) and a proportion of the aggregate should have a density of less than 2000kg/m 3. Lightweight concrete can be specified using the notation LC for the strength class, e.g ...
Lightweight concrete, similar to normal weight concrete, is a mixture of water, Portland cement or Ordinary Portland Cement (OPC), and aggregate. It is classified as structural or nonstructural concrete depending on strength and compression rating, generally determined by the type of aggregate material used in the concrete mix.
The light-weight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used, which make the concrete weigh less. The lightweight aggregates used are usually expanded shale, clay, or slate materials that have been fired in a rotary kiln to give them a porous structure, similar to volcanic rock.
