1. Hardening concrete : measurments and evaluation of non-elastic deformation and associated restraint stresses
Abstract : If a structural member of hardening concrete is restrained to some degree against expansion and contraction during the heating phase of the hydration process and the subsequent contraction phase, stresses will be induced. The issue of primary interest is whether or not these induced stresses will lead to cracking. READ MORE

2. Concrete Structures Subjected to Fragment Impacts
Abstract : As concrete is commonly used for protective structures, how a blast wave and fragment impacts from an explosion affect the concrete is an important issue. Concrete subjected to explosive loading responds very differently from statically loaded structures. READ MORE

3. Structural Behaviour of Deteriorated Concrete Structures
Abstract : A growing concern for better assessment of existing concrete structures has revealed a need for improved understanding of the structural effects of deterioration. The two most common causes of deterioration in concrete structures are freezing of the concrete and corrosion of the reinforcement. READ MORE

4. Modelling of Concrete Subjected to Cyclic Loading
Abstract : The infrastructure of today depends heavily on concrete structures. Most of these structuresare subjected to repeated loads, known as fatigue or cyclic loads: the loads weakenthe structure. As this phenomenon is of high cost to society, a deeper understanding ofthe deterioration process of cyclic loading would be beneficial. READ MORE

5. Strengthening reinforced concrete structures with FRP composites
Abstract : Civil infrastructures made of reinforced concrete (RC) play an important role in the economic activities and services of society. However, signs of deterioration and functional deficiency are commonly found in existing RC structures. Thus, there is a great demand for upgrading the capacity and performance of existing concrete structures. READ MORE
