波特兰水泥是混凝土中所使用的主要粘合剂，其生产过程中大量的二氧化碳排放量造成了人们迫切需要寻找环保材料作为替代品。在大多数发展中国家，大量农业废弃物（如椰子壳）的可用性为探索如何将这些材料作为粘合剂组合物回收到混凝土中开辟了一条途径。大多数固体农业废弃物的燃烧会产生灰烬，灰烬可用于替代波特兰水泥作为混凝土中的粘合剂。本文介绍了椰壳灰对混凝土和易性、力学性能和隐含碳影响的实验研究结果。本文总共有五种混合物是用椰壳灰代替硅酸盐水泥制成的，最高可达20%。该论文的结果表明，可将椰壳灰掺入混凝土混合物中以减少其隐含碳。当用椰壳灰代替20%的硅酸盐水泥时，隐含碳减少了约15%。将椰壳灰掺入混凝土混合物中还可以提高机械性能，最多可替代10%波特兰水泥。掺入10%椰壳灰替代波特兰水泥的混合物的压缩、拉伸和弯曲强度比不含椰壳灰的对照混合物高12%、10%和9%。
