Influence and Mechanism Research of Hydration Heat Inhibitor on Low-Heat Portland Cement
Frontiers in Materials, 2021 A kind of microcapsule sustained-release–type hydration heat inhibitor (MSR) was prepared. The effect of MSR on semi-adiabatic temperature rise, setting time, and strength of low-heat Portland cement was investigated.

Chemistry–Methods, EarlyView.We present a scalable, low‐emission approach to transform waste into sustainable building materials via carbon mineralization and 3D printing. Calcium from recycled concrete reacts with CO2 to form CaCO3, which is combined with lignin and sawdust to create printable inks. The resulting 3D‐printed structures offer mechanical robustness and a closed‐loop

A review of the methods used to study biocompatibility of Portland cement-derived materials used in dentistry [PDF]
, 2006 Advanced restorative dentistry may necessitate the need for surgical intervention to the infected root apex. Once access to the root end is achieved, the root apex is resected and filled with a dental restorative material.

A Unique Relationship Determining Strength of Silty/Clayey Soils - Portland Cement Mixes [PDF]
, 2016 This technical note advances the understanding of the key parameters controlling unconfined compressive strength (qu) of artificially cemented silty/clayey soils by considering distinct moisture contents, distinct specimen porosities (η), different ...

The Depositional Record, EarlyView.Shallow‐marine mudstone of the Cretaceous Kaskapau Formation in the British Columbia foredeep preserves a 185 m thick record of OAE2. The organic carbon‐isotope and osmium‐isotope excursions can be correlated in detail with other Cenomanian–Turonian boundary sections around the world.

Modelling the effects of waste components on cement hydration [PDF]
, 2000 Ordinary Portland Cement (OPC) is often used for the Solidification/Stabilization (S/S) of waste containing heavy metals and salts. These waste componenents will precipitate in the form of insoluble compounds onto unreacted cement clinker grains ...
