摘要

这篇综述论文侧重于利用各种海贝灰，包括毛蚶、蛤蜊、牡蛎、软体动物、长春花、蜗牛和绿贻贝的贝壳灰，作为水泥的部分替代品。其目的是促进环境的可持续发展，缓解与全球变暖相关的问题。众所周知，水泥生产的各个阶段都会对环境产生重大影响，包括粉尘和气体造成的空气污染，以及采石和碾磨过程中的噪音和振动。建议的解决方案之一是采用改性水泥，改性水泥是指设计用于匹配或超越波特兰水泥性能的胶凝材料，同时掺入回收材料和废料，从而减少对原材料的需求，促进建筑业的可持续发展。在混凝土中利用海贝灰作为水泥的部分替代品，有可能节省大量能源，并具有显著的环保优势。以往的研究探讨了用海贝灰替代物生产的混凝土的化学和机械性能，包括比重、化学成分、抗压强度、抗拉强度和抗折强度。结果表明，海贝灰在水泥中的最佳替代比例为 4-5%。

Review on Seashell Ash as Partial Cement Replacement

The review paper focuses on utilizing various sea shell ashes, including cockle, clam, oyster, mollusc, periwinkle, snail, and green mussel shell ash, as partial replacements for cement. It aims to promote environmental sustainability and mitigate the issues associated with global warming. Cement production is known to have significant environmental impacts across all stages, including air pollution through dust and gases, as well as noise and vibration during quarrying and milling processes. One proposed solution is the adoption of modified cement, which refers to cementitious materials designed to match or surpass the performance of Portland cement while incorporating recycled and waste materials, thereby reducing the demand for raw materials and promoting sustainability in construction. Utilizing sea shell ash as a partial replacement for cement in concrete has the potential to yield substantial energy savings and offer significant environmental advantages. Previous investigations have explored the chemical and mechanical properties of concrete produced with sea shell ash replacements, including specific gravity, chemical composition, compressive strength, tensile strength, and flexural strength. The results indicate that the optimal replacement percentage for sea shell ash in cement lies within the range of 4–5%.
