Development of assembled permanent formwork using ultra high toughness cementitious composites

Development of assembled permanent formwork using ultra high toughness cementitious composites The present investigation shows new development on assembled permanent formwork using ultra high toughness cementitious composites with low permeability and high crack resistance. A bidirectional keel formwork is designed to act as surface cover to prevent corrosion of steel reinforcements for structures under aggressive environment. Main attention is focused on mechanical aspects of a reinforced concrete specimen made with permanent formwork in this article. The flexural behavior of specimen is measured with four-point bending test and experimental results are then presented. A method is proposed to predict the load capacity and displacement of specimen and theoretical prediction shows a coincidence with test results. Furthermore, a series of design details and suggestions are discussed. The results of this investigation show that specimen made by ultra high toughness cementitious composite assembled permanent formwork presents higher load-carrying capacity and more ductile behavior compared with reinforced concrete specimen. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advances in Structural Engineering SAGE

Abstract

The present investigation shows new development on assembled permanent formwork using ultra high toughness cementitious composites with low permeability and high crack resistance. A bidirectional keel formwork is designed to act as surface cover to prevent corrosion of steel reinforcements for structures under aggressive environment. Main attention is focused on mechanical aspects of a reinforced concrete specimen made with permanent formwork in this article. The flexural behavior of specimen is measured with four-point bending test and experimental results are then presented. A method is proposed to predict the load capacity and displacement of specimen and theoretical prediction shows a coincidence with test results. Furthermore, a series of design details and suggestions are discussed. The results of this investigation show that specimen made by ultra high toughness cementitious composite assembled permanent formwork presents higher load-carrying capacity and more ductile behavior compared with reinforced concrete specimen.
