These and other factors meant that it took a year of testing before the new composition was successfully arrived at. The first four months were spent in the laboratory finding the best ratio of constituents, after which research shifted to Talinpu for exposure to the on-site atmospheric conditions and cooperation with the mixing plant.
種種特殊情況，使得這項結合爐石與飛灰、水泥的混凝土新配方，足足實驗了一年才成功。前四個月在實驗室中找出最佳混合比例；後來則搬到大林蒲現場配合當地溫度、濕度及預拌廠作業，再做實地演練。
