Civil engineering structures are part of our cultural heritage. The story of who we are can be told, in part, by what we have built. There have been pivotal moments in civil engineering design history wherein a master engineer creates a pioneering structure. One major example is Anton Tedesko’s 1936 Hershey Ice Arena, the first large-scale thin shell concrete roof in the United States. Tedesko ...

An investigation on the effect of sisal fiber partially replaced cement with Groundnut Shell Ash in Concrete was carried out. Sisal 3.5cm length which forms 1% mix by weight groundnut shell ash as a partial replacement for used preparing concrete specimen. Compressive strength test out using 0%, 5%, 10%, 15%, 20%, 25% and 30% at different curing ages 7, 14, 21 28 days. It observed that 7 14days...

We evaluate several features of capacity planning approaches used in practice and make concrete suggestions for practitioners. We run four experiments to determine the eeects of large vs. small time buckets, the cost implications of using heuristics, frequent vs. less frequent forecasting and planning, and joint optimization of tool and oor-shell expansions vs. sequential optimization. We use i...

Calcium carbonate and calcium-magnesium carbonate in the form of limestone, dolomite, marl, chalk, and Oyster shell are one of the most widely utilized non-metallic materials in the industrial world. The largest use of limestone or calcium carbonate is in the cement industry where it is used as a source of CaO and also in the concrete industry where it is used as the primary coarse aggregate. F...
