1. 1. Modelling of a Heat Conduction Calorimeter Used in Cement Plant Automation

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Hassan Alzeidi; [2022]
   Keywords : Technology and Engineering;

   Abstract : A model is used to describe a system physically or mathematically and to give information about changes in the system variables. Physical knowledge about the system and its quantities can be useful to build a physical model obeying the laws of nature. READ MORE

3. 2. State of the Art Report on Cement Based Grout Properties and Dynamic Grouting

   University essay from KTH/Jord- och bergmekanik

   Author : Bowen Meng; [2021]
   Keywords : Dynamic grouting; filtration; rheology; grouting phase;

   Abstract : Dynamic grouting in rock mass has been studied since 1985 while desired penetration in rock masses with fine fractures is still a challenge because of uncertainty and complexity in the grouting process. This has attracted the attention of researchers in different countries and regions, especially in some Nordic countries such as Sweden. READ MORE

4. 3. Standardization and optimization of index for 28 day strength for cement made from standard clinker

   University essay from KTH/Kemiteknik

   Author : Anton Hermansson; [2020]
   Keywords : ;

   Abstract : This project regards the prediction of 28 day compressive strengths of cement. Using traditional multivariate analysis in combination with Artificial Neural Networks indexes have been developed which makes these predictions possible. READ MORE

5. 4. Simulation of Hardening of the MahanaKhon Tower Mat Foundation

   University essay from KTH/Betongbyggnad

   Author : Zakaria Kazi-tani; [2019]
   Keywords : Hydration; MahanaKhon tower; mat foundation; young concrete; temperature development; thermal stresses; cracking; fly ash; finite element analysis; COMSOL Multiphysics; Hydratation; MahanaKhon tower; bottenplatta; ung betong; temperaturutveckling; termiska spänningar; sprickbildning; flygaska; finita elementanalys; COMSOL Multiphysics;

   Abstract : 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.

6. 5. Alternative methods to prevent thermal cracking in concrete

   University essay from

   Author : Alexander Barchin; Navid Sedighi; [2019]
   Keywords : Massive concrete structures; heat development; cement hydration; temperature reduction; cracking; fly ash; ice; coarse aggregates; cooling methods; practical tests.; Massiva betongkonstruktioner; värmeutveckling; cementhydrataion; temperaturreducering; sprickbildning; flygaska; is; grov ballast; kylningsmetoder praktiska försök.;

   Abstract : 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. READ MORE
