Lightweight Concrete: Types, Properties, Merits Demerits

The main specialties of lightweight concrete are its low density (300 kg / m3 to 1850 kg / m3) and thermal conductivity. Due to lightweight and high strength to mass ratio their use results in lesser steel consumption. Here we will learn about Lightweight concrete, types of foam concrete, advantages disadvantages of lightweight concrete.

Lightweight Concrete - an overview ScienceDirect Topics

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.

Seismic Performance of Lightweight Concrete Structures

2018-2-6  Concrete structures are prone to earthquake due to mass of the structures. The primary use of structural lightweight concrete (SLWC) is to reduce the dead load of a concrete structure, which allows the structural designer to reduce the size of the structural members like beam, column, and footings which results in reduction of earthquake forces on the structure.
