Cement Brand and Preparation Effects Cement-in-Cement Mantle Shear Strength [PDF]

open access: yesHIP International, 2014
Creating bi-laminar cement mantles as part of revision hip arthroplasty is well-documented but there is a lack of data concerning the effect of cement brand on the procedure. The aim of this study was to compare the shear strength of bi-laminar cement mantles using various combinations of two leading bone cement brands. Bi-laminar cement mantles were

Cement-Polymer Composites for Oilwell Cementing [PDF]

open access: yesOil & Gas Science and Technology - Revue de l'IFP, 2009
The selection of an optimal cementitious material is critical to maintain zonal isolation for the lifetime of oil & gas or gas storage wells not only for primary cementing but also after well abandonment. Polymer powder/cement composites present good mechanical and durability properties since polymer latex promotes improved adhesion and flexibility to ...

The sponge effect and carbon emission mitigation potentials of the global cement cycle

open access: yesNature Communications, 2020
Cement plays a dual role in the global carbon cycle like a sponge: its massive production contributes significantly to present-day global anthropogenic CO2 emissions, yet its hydrated products gradually reabsorb substantial amounts of atmospheric CO2 ...
