1. Fabricability of a high alloy tool steel produced with LPBF, with a focus on part geometry
Master-uppsats, Karlstads universitetSammanfattning : Additive manufacturing (AM) is a promising manufacturing process that provides that ability to fabricate components with complex geometries with relatively low lead times compared to other manufacturing processes. This allows for more freedom of design, as prototypes can easily be produced throughout the development process. LÄS MER
2. Bacteria - based self - healing mortar with bio - plastic healing agents : Comparative analysis on quantification and characterization of self-healing by various experimental techniques
Master-uppsats, KTH/BetongbyggnadSammanfattning : Crack formation in concrete structures due to various load and non-load factors leading to degradation of service life is very common. Repair and maintenance operations are, therefore, necessary to prevent cracks propagating and reducing the service life of the structures. LÄS MER
3. 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. LÄS MER
4. 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
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
