1. 1. Applied Modeling of Moisture Phenomena in Concrete

   Författare :Marcin Stelmarczyk; Andrzej Cwirzen; Hans Hedlund; Klaas van Breugel; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; Modeling degree of hydration; Modeling chemically bounded water; Modeling moisture sorption; Modeling moisture transport; Hysteresis; Byggmaterial; Building Materials;

   Sammanfattning : This thesis contains new and improved calculation models, based on applied research merging numerical modeling and material research, in the areas of hydration and chemical binding of water, sorption of moisture and transport of moisture in concrete. The proposed model for hydration and chemical binding of water is based on general kinetics modeling and calculates degree of hydration directly, without using of equivalent time of maturity.

   Sammanfattning : Conventional drug administration technologies display poorcontrollability, and lead to high plasma concentrations andshort duration times, which frequently lead to adverse effects.Controlled release technology aims at predictable andreproducible delivery of an active substance over an extendedperiod of time, yielding optimal response and prolongedefficiency, and thus offering considerable improvement of manytreatments.
