Properties of Artificial Lightweight Aggregates from Various Pozzolan Materials – A Review [PDF]

open access: yesArchives of Metallurgy and Materials
The use of lightweight aggregate can bring advantages to the construction field. Lightweight aggregate has been used due to its lower density and can reduce the dead load applied to the structural elements. Due to the number of natural resources, such as

Structural Lightweight Concrete Containing Recycled Lightweight Concrete Aggregate

open access: yesKSCE Journal of Civil Engineering, 2018
In this paper, Structural Lightweight Concrete (SLC) containing Recycled Lightweight Aggregate (RLA) is described. Damaged lightweight concrete was used as RLA by crushing it into fine particles, and used to replace fine limestone aggregate of up to 45% by weight.

Structural lightweight aggregate concrete with reduced density— lightweight aggregate foamed concrete

open access: yesInternational Journal of Cement Composites and Lightweight Concrete, 1980
In order to reduce the density of concrete for load bearing and stiffening structural members and to improve the thermal insulation properties and thus extend the scope of application for structural lightweight concrete, closed-texture lightweight concretes are required which, while possessing adequate compressive strength, have densities of less than ...
