1. Simulation of Hardening of the MahanaKhon Tower Mat Foundation
Master-uppsats, KTH/BetongbyggnadSammanfattning : Cement hydration is the result of a series of simultaneous chemical reactions occurring during the production of concrete. An excessive amount of heat is generated, which consequently may give rise to thermal stresses and cause early age cracks in concrete that may affect its structural integrity, and load bearing capacity.

2. Alternative methods to prevent thermal cracking in concrete
M1-uppsats,Sammanfattning : In the construction industry, concrete is the most common material, because of its good properties such as compressive strength and endurance. Concrete is a composition of several different materials where one of the main components is cement. When the hydration process starts, large amount of heat is generated. LÄS MER
3. Prediction of early age and time dependent deformations in a massive concrete structure
Master-uppsats, KTH/BetongbyggnadSammanfattning : The heat development that occurs due to the hydration of cement is important to consider during casting of massive concrete structures. By using computer programs that are based on finite element methods (FEM), simulations can be performed on the heat- and strength development. LÄS MER
4. Thermal cracking of a concrete arch dam due to seasonal temperature variations
Master-uppsats, KTH/BetongbyggnadSammanfattning : Concrete dams located in northern regions are exposed to large seasonal temperature variations. These seasonal temperature variations have resulted in cracking in thin concrete dams. Continuous monitoring and evaluation of existing dams are important to increase the knowledge about massive concrete structures and to ensure dam safety. LÄS MER
5. Temperature reduction during concrete hydration in massive structures
Master-uppsats, KTH/BetongbyggnadSammanfattning : Concrete is one of the most used building materials in the world because of its good properties. However, cement which is one of the main components in concrete, produces a high amount of heat during the hydration process. The generated heat leads to temperature rise inside the structure. LÄS MER
