Isothermal Calorimetry Study of Blended Cements and its Application in Numerical Simulations

Xiong, X. (author), Van Breugel, K. (author)

Apparent activation energy (E) is generally used to consider the effect of temperature on the kinetics of cement hydration in the numerical simulation of cement hydration processes. This paper deals with an experimental study on the kinetics of Portland cement and blast furnace slag cement using isothermal Calorimetry at 20, 30, and 40°C. Two...

A novel Planar Magnetic Bearing and Motor Configuration applied in a Positioning Stage

Molenaar, A. (author)

This thesis presents the design and implementation of a fully contactless high precision magnetically suspended position stage with large planar stroke. This stage is the first which is suitable for practical application in vacuum. The underlying electromechanical working principles, modelling and analysis, the mechanical and electrical design,...

'Active' Thin Sections

De Rooij, M.R. (author), Bijen, J.M.J.M. (author)

Optical microscopy using thin sections has become more and more important over the last decade to study concrete. Unfortunately, this technique is not capable of studying actually hydrating cement paste. At Delft University of Technology a new technique has been developed using 'active' thin sections. This technique allows microscopic...
