A Comparative Study on Zn and Zn-Y Coatings on 42CrMo Steel by Pack Cementation Process
International Journal of Electrochemical Science, 2017 Zn and Zn-Y coatings on 42CrMo steel were prepared by pack cementation process at 360°C, 370°C, 380°C, 390°C and 400°C for 4 h, respectively. The purpose of this work was to comparatively study the differences on the microstructure and corrosion behavior

Elastic moduli of cemented sphere packs
Mechanics of Materials, 1999 Abstract We present a method for estimating the effective elastic moduli of a dense random pack of identical elastic spheres with elastic binder (cement). The cement concentration in the pore space varies from a few percent (where it fills the space at grain contacts) to 100%.

Influence of packing and dispersion of particles on the cement content of concretes [PDF]
Revista IBRACON de Estruturas e Materiais, 2017 Abstract Due to environmental issues, the concrete chain seeks to reduce CO2 emissions. However, growing demand from developing countries causes the increase of CO2 emissions in production to exceed decreases generated by industrial actions, such as improving kilns and clinker replacement. New strategies are important.
