Abstract

In the realm of modern construction practices, the demand for innovative materials capable of meeting structural requirements while mitigating the inherent limitations of traditional building materials has been escalating. Concrete, a quintessential component in construction, has undergone extensive adaptations to address these challenges. One significant area of development is lightweight concrete, which presents an alternative to conventional concrete due to its reduced density and enhanced structural efficiency. The necessity for lightweight concrete arises from various factors, including the need to alleviate excessive structural dead loads, enhance seismic resistance, and expedite construction processes. However, while artificial lightweight aggregates have historically dominated this field, escalating production costs and environmental concerns have spurred a reinvigorated interest in natural alternatives, particularly perlite. This research endeavours to delve into the realm of perlite-based lightweight concrete, seeking to optimize its mechanical strength, durability, and structural performance for widespread application in the construction industry.
