Mermer atölyelerinden kaynaklanan atıkların beton üretiminde ince ve kaba agregalara alternatif olarak kullanılması

The marble industry generates significant waste that negatively impacts the environment. Unfortunately, only a small portion is utilized in various applications. These vast quantities of waste, often dumped indiscriminately, can hinder soil porosity and permeability, leading to reduced water absorption. This can contribute to soil-borne diseases, particularly respiratory issues amongst nearby residents, while also polluting groundwater. Moreover, the visual impact on the landscape is undeniably detrimental. This study investigated the potential of utilizing waste from marble workshops as an alternative to traditional Libyan aggregates (ploughing and blasting) in varying proportions for regular concrete production. The research explored both coarse and fine aggregates derived from marble waste. Fine aggregate was incorporated at various ratios (10%, 30%, and 50%) into the standard concrete mix alongside local sand. The suitability of these aggregates was evaluated through comprehensive mechanical and physical testing, encompassing not only the aggregates themselves but also the resulting concrete's workability and compressive strength. The findings encourage the use of marble waste as both coarse and fine aggregate in regular concrete. Notably, the mechanical properties of the obtained aggregates met all relevant specifications. The concrete containing 50% coarse marble aggregate alongside blastingaggregates exhibited a higher compressive strength than the reference mix crafted with local aggregates. Similarly, the concrete incorporating 30% fine marble aggregate displayed greater compressive strength compared to the standard formulation using local sand. Based on these promising results, we recommend further exploration of utilizing marble workshop waste as an alternative to traditional aggregates within the boundaries established by this research.
