Nanostructure and Nanomechanics of Cement: Polydisperse Colloidal Packing [PDF]
Physical Review Letters, 2012 Cement setting and cohesion are governed by the precipitation and growth of calcium-silicate-hydrate, through a complex evolution of microstructure. A colloidal model to describe nucleation, packing, and rigidity of calcium-silicate-hydrate aggregates is proposed.

Sustainable Blended Cements—Influences of Packing Density on Cement Paste Chemical Efficiency [PDF]
Materials, 2018 This paper addresses the development of blended cements with reduced clinker amount by partial replacement of the clinker with more environmentally-friendly material (e.g., limestone powders). This development can lead to more sustainable cements with reduced greenhouse gas emission and energy consumption during their production.

Titanium diffusion coatings on austenitic steel obtained by the pack cementation method [PDF]
Journal of the Serbian Chemical Society, 2009 The surface of specimens made of 316L austenitic steel was modified by titanium diffusion. The diffusion coatings were obtained by packing in a powder mixture consisting of titanium powder, NH4Cl and Al2O3 powder. The procedure required high temperatures,

Multilayer-Forming Behavior of Cr Nitrides and Carbides for Thermoreactive Deposition
Metals, 2018 The effect of a nitride layer on the forming behavior of CrN and (Cr, Fe)7C3 multilayers for thermoreactive deposition (TRD) was investigated. Plasma nitriding followed by TRD (PN-TRD) produced a larger coating thickness than the case of direct TRD with ...
