Experimental investigation of M30 grade lightweight concrete using sintered aggregate

Lightweight concrete (LWC) is gaining traction in contemporary construction due to its reduced density and enhanced thermal characteristics. Among various LWC types, sintered aggregate-based concrete is notable for its capability to lessen weight while satisfying strength standards. Although earlier studies, such as the one by Saha, Guntakal, and Selvan (2018) that investigated the properties of lightweight concrete by varying different parameters, have analyzed various lightweight aggregates, research on the combination of sintered and conventional aggregates in M30 grade concrete remains scarce. This study seeks to examine how varying proportions of these aggregates influence the mechanical properties of M30 lightweight concrete, aiming to find an ideal mix that offers a balance between strength, durability, and weight reduction. For this investigation, three distinct mix proportions were formulated using both sintered and traditional aggregates. Following standardized methods, the concrete samples were tested for compressive strength to ensure accurate and reliable outcomes. By studying the effects of sintered aggregates on concrete performance, this research aims to identify the most efficient mixture. The results from this study could significantly contribute to the development of lightweight structural concrete, especially for uses such as deck slabs and precast components. By decreasing the overall dead load of structures without sacrificing strength, this method provides a sustainable and effective solution to meet the needs of modern construction.
