Possibilities of the use of isoperibolic calorimetry for assessing the hydration behavior of cementitious systems

Possibilities of Use of Isothermal and Isoperibolic Calorimetry to Study the Effect of Zinc on Hydration of Cement Blended with Fly Ash

“…The main differences in results are caused mainly by the measurement conditions since in the case of isothermal calorimetry the measurement is performed under exactly defined conditions, while the isoperibolic measurements proceed under real conditions. The combination of those two methods brings an important information about the course of particular reactions (isothermal calorimetry) and the comparison with the process in real environment (isoperibolic calorimetry) [20].…”

“…For the calculation of total released heat the subsequent numerical data integration is performed. Data required for this calculation was gained from the device calibration [20]. The hydration heat is evolved during the hydration and the sample heats up.…”

“…During isoperibolic calorimetry the same heating occurs as during the hydration under real conditions. For the study of hydration reactions, it is therefore advantageous to use a combination of both these calorimetric methods [20].…”

Concrete for Construction of Hydrotechnical Structures

“…і за оригінальними методиками (оцінка тепловиділення при гі-дратації цементів методом напівадіабатич-ної калориметрії) [9][10].…”

Determination of the bond strength of treated wood strands embedded in a cement matrix by means of a pull-out test

“…Reinforcing concrete with fibres inhibits crack initiation and growth, hence increasing fracture toughness of concrete (Issa et al 1996). Conventional test methods (Jorge et al 2004) of inorganic bonded wood composites measure the compatibility between wood and cement by measurement of the hydration characteristics (Alberto et al 2000;Wei et al 2000a, b;Brandstetr et al 2001;Karade et al 2003), as well as testing mechanical properties of cured composites (Lee and Hong 1986;Wei et al 2003).…”
