Strength and Durability Characteristics of Light Weight Concrete Mixes

Abstract

The history of Light Weight Concrete spans over two millennia, yet it still has ongoing upgrades in its technology. The paper consists of a retroactive approach, which shapes out thought in manifold practicalities, that have been covered by Light Weight Concrete, since the twentieth century. Even though Light Weight Concrete is well known, and has its applicative potential proven through multiple experiments and tests over the last century. Yet, today we witness precariousness and unpredictability in its use and applications. It is thus, Light Weight Concrete in its various forms and mixes have been studied in a wide lens, especially focusing on the present-day combinations, after great number of trial and error, and the practice of designing its mixes after the study of each of the mixes. A particular obstacle faced during the design of the Light Weight Aggregate Concrete had been to blend its mixes, during its production, as their properties often differ quite a lot from conventional concrete. Hence, those properties, which have potentially been part of anomalies and doubts, have been highlighted, such as the appellation and informatory data inferred from these experiments. The recurring issues related to the mix design, during the production of the Light Weight Concrete have been clarified and its unintended side effects or by-products have been briefly elaborated, by performing tests, on specimens of mix designs, that were cast as part of this project. A detailed scrutiny was made and its perspective was provided, based on the information given in the prevailing concrete benchmarks, related to the physical and structural features of moulded Light Weight Concrete and are addressed with regards to some unintended consequences seen. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.
