Modelling The Addition Of Limestone In Cement Using Hydcem, Niall Holmes, Denis Kelliher, Mark Tyrer

Conference papers

Hydration models can aid in the prediction, understanding and description of hydration behaviour over time as the move towards more sustainable cements continues.

HYDCEM is a new model to predict the phase assemblage, degree of hydration and heat release over time for cements undergoing hydration for any w/c ratio and curing temperatures up to 450C. HYDCEM, written in MATLAB, complements more sophisticated thermodynamic models by predicting these properties over time using user-friendly inputs within one code. A number of functions and methods based on up to date cement hydration behaviour from the literature are hard-wired into the code along with …

On The Formation Of The Variational Equation Of Motion And Boundary Value Problems Of Thin-Walled Axisymmetric Shell Structures, A. Abdusattarov, F.E. Abduqodirov, N.H. Sabirov

Journal of Tashkent Institute of Railway Engineers

The article deals, on the basis of the Hamilton-Ostrogradsky variational principle, a system of differential equations of motion of axisymmetric shell structures with the corresponding boundary and initial conditions is derived. The boundary problem for cylindrical and spherical shell structures is formulated
