  1. 1. Quality Control of Concrete Piles Based on Historical Data : Machine learning of concrete piles production line

    University essay from Karlstads universitet

    Author : Deco Josephson; [2021]
    Keywords : Dataanalys; Concrete; Concrete pile; Machine learning; Betong; betongpåle; betong bortslagning; Maskin inlärning.;

    Abstract : This master thesis investigates the parameters influencing the quality of concrete piles produced by NCC in Sweden. Furthermore, the thesis provides an in-depth review of the production and existing issues associated with concrete pile production. READ MORE

  3. 2. Indirect methods as quality control of cemented hydraulic fill : Renström mine, Boliden mineral AB

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Amanda Rask; [2019]
    Keywords : Backfill; CHF;

    Abstract : The Renström mine, Boliden Mineral AB, uses, among other methods, the Transverse long hole stoping method with backfill. The mine uses a cement-stabilized hydraulic fill (CHF), which is a mixture of enrichment sand, cement and water. The most important factor in relation to strength is the water cement ratio.

  4. 3. 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.

  5. 4. Prediction of early age and time dependent deformations in a massive concrete structure

    University essay from KTH/Betongbyggnad

    Author : Ali Aghili; Haris Ribac; [2018]
    Keywords : Early age concrete; hydration of cement; Storfinnforsen; ConTeSt; crack risk; temperature development; strain; mass concrete structures; measurement plan; Ung betong; hydratation av cement; Storfinnforsens kraftverk; ConTeSt; sprickrisk; temperatur; töjning; massiva konstruktioner; mätningsplanering;

    Abstract : 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. READ MORE

  6. 5. Determination of Shrinkage Crack Risks in Industrial Concrete Floors through Analyzing Material tests

    University essay from KTH/Bro- och stålbyggnad

    Author : Maitham Hamad; [2012]
    Keywords : Industrial concrete floors; laboratory tests; crack risk; free shrinkage; restrained shrinkage; creep;

    Abstract : The industrial concrete floor is a very important part of an industrial building, distribution center, storage or shopping mall, and it must have high quality surfaces for operation. To achieve the high quality we must know the problems and how to treat them. READ MORE
