In the mixtures, basaltic-pumice (scoria) was used as lightweight aggregate. A control lightweight concrete mixture made with lightweight basaltic-pumice (scoria) containing normal Portland cement as the binder was prepared. The control lightweight concrete mixture was modified by replacing 20% of the cement with fly ash.

Seismic Performance of Lightweight Concrete Structures

Feb 06, 2018  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.

Lightweight concrete is not a new material; in fact it has been observed since 7000 B.C. At that time it was made with local materials such as quick lime, water, and stone aggregates. Lightweight high performance concrete of today is still made with approximately the same materials: portland cement, water, lightweight aggregates, and sand.

What is Lightweight Concrete? Most of the lightweight concrete mix is made with lightweight aggregates. Lightweight concretes strengths are generally in the range of 0.3 N/mm2(44 psi) to 40 N/mm2( 5800 psi) and cement content in the range of 13 lb/ft3 (200 kg/m3). The density of aggregate plays a vital role in the strength of lightweight concrete.
