摘要

In the modern era, extensive research is focused on discovering suitable alternatives to traditional cementitious materials to trim down the impression of carbon footprints in the atmosphere. Various materials including “fly ash, silica fume, ground granulated blast furnace slag, and metakaolin were being explored to partially or fully replace cement in concrete production.“ This study aims to evaluate the compressive strength and durability efficiency of alccofine as a partial replacement for binder in concrete mixes (M40). Cement has been partially substituted with alccofine at 0, 5, 10, 15 and 20%. After 28 days curing phase, all the samples underwent exposure to chloride and sulphate attack for 90 days. The compressive strength and weight of the sample were taken before the chloride and sulphate attack. Based on experimental outcomes, higher compressive strength and a lower loss percentage of compressive strength have been observed in samples with 15% of alccofine. Similarly, the weight loss percentage has been minimal in samples with 15% alccofine followed by 10% alccofine samples. Notably, it has been observed that 15% of Alccofine with cement yields superior performance compared to other mixes. The optimal percentage of alccofine replacement falls within the range of 10–15%. Furthermore, it has been established that the efficiency of alccofine displays excellent performance in terms of strength and endurance.
