Precast Concrete Elements

Lattice-girder floor slabs and double-wall elements have been successfully used in building and industrial construction for decades. These precast elements of 50 – 70 mm thickness serve as permanent formwork for the subsequently added in-situ concrete creating a monolithic structure. The high prefabrication level allows the construction period to be significantly minimized. The main goal is the...

Optimization of Precast Prestressed Concrete Bridge Girder Systems

60 A practical approach to the optimal design of precast, prestressed concrete highway bridge girder systems is presented. The approach aims at standardizing the optimal design of bridge systems, as opposed to standardizing girder sections. Structural system optimization is shown to be more relevant than conventional girder optimization for an arbitrarily chosen structural system. Bridge system...

Foam Concrete Precast Elements in Composite Concrete-GFRP Plate Girders

This paper is focused on using foam concrete as structural element in polymer-concrete composite plate girders. Trial mixes of foam concrete and different proportions of foam agent were considered to obtain the suitable mix that can be used as structural element in composite girders system. Details of the experimental investigations on foam concrete precast slabs and polymer-concrete composite ...

Iodine deficiency in industrialized countries.

The recent report of poor iodine status in the UK is a wake-up call to health authorities in industrialized countries who have been slow to grasp that iodine deficiency (ID) is not confined to developing countries. Australia, New Zealand, Belgium, Norway and now the UK are all mildly iodine deficient. In the US, iodine intakes have fallen, and it is uncertain whether status is adequate in pregn...

Productivity Growth in Industrialized Countries

USA. We have benefited from conversations with James F. Burgess, Jr. and David C. Wheelock. We are grateful for financial support from the Belgian Government (" Projet d'Actions de Recherche Concertées, PARC no. 93/98–164), and from the Management Science Group, US Department of Veterans Affairs. We alone, of course, are responsible for any remaining errors in the current text.
