The 30,000-tonne (33,000-ton) post-tensioned concrete silo built at Fisherman's landing neer Gladstone, Queensland, Australia, is part of a larger clinker cement plant. Cement clinker is charged to the silo at higher than ambient temperature. The method for predicting the maximum temperature differential between the inner and outer faces of the silo wall, for use in its structural design, is presented. A comparison is made with temperatures and differentials measured during subsequent operation of the plant. The level of clinker fill in the silo is found to have a significant effect on the maximum temperature differential.
