本研究旨在找出印度尼西亚废能利用作为碱激活砂浆粘结剂的贡献。在之前的一项研究中，研究人员调查了日本由 F 级粉煤灰/GGBFS/微硅粉制成的砂浆。加入 GGBFS 是为了缩短/标准化凝结时间，加入微硅粉是为了提高砂浆性能。然后，利用印度尼西亚丰富的废料（即 C 级粉煤灰）制作立方砂浆样本，继续进行这项研究。与日本的 F 级粉煤灰膏相比，印度尼西亚的 C 级粉煤灰膏的凝固时间非常快。喷砂作为印度尼西亚丰富的废料，被替换为C级粉煤灰，以延长浆体的凝固时间并改善砂浆样本压缩测试的标准偏差。另一方面，喷砂废料的添加具有负面影响，因为它降低了砂浆样本的抗压强度。
This research is to find out the contribution of waste energy utilization in Indonesia as a binding agent of alkali-activated mortar. In a previous study, researchers investigated mortar made from class F fly ash/GGBFS/micro-silica in Japan. The inclusion of GGBFS is to shorten/normalize the setting time and microsilica is to improve mortar performance. This research is then continued by using abundant waste material in Indonesia, namely class C fly ash, by making cubic mortar specimens. Setting time of class C fly ash paste from Indonesia is very fast, in contrast to that of class F fly ash paste from Japan. Sandblasting as abundant waste material in Indonesia is substituted to class C fly ash to lengthen the setting time of paste and to improve standard deviation of a compressive test of mortar specimens. On the other hand, the addition of sandblasting waste has a negative effect, because it reduces a compressive strength of mortar specimens.
