Porous Bioglass Scaffold for Orthopedics Applications

open access: yesMedžiagotyra, 2016
This work aims to contribute for the development of bioglass scaffolds to be used in bone tissue regeneration. Starting from the classic quaternarian composition of the bioglass 45s5 it was added potassium oxide and magnesium oxide in order to obtain the

Setting control of completely recyclable concrete with slag and aluminate cements [PDF]

open access: yes, 2016
A completely recyclable concrete (CRC) is designed to have a chemical composition equivalent to the one of general raw materials for cement production. By doing so, this CRC can be used at the end of its service life in cement manufacturing without the ...

Effect of calcium aluminate cement variety on the hydration of Portland cement in blended system [PDF]

open access: yes, 2014
Two kinds of CACs with different monocalcium aluminate (CA) contents were used in the PC/CAC (PAC) mixtures. Effects of CA and CACs on the properties of PAC were analyzed by setting times and the compressive strength tests, and also by means of ...

Synchrotron Radiation Pair Distribution Function Analysis of Gels in Cements [PDF]

open access: yes, 2017
The analysis of atomic ordering in a nanocrystalline phase with small particle sizes, below 5 nm, is intrinsically complicated because of the lack of long-range order.

Designing corrosion resistant systems with alternative cementitious materials

open access: yesCement, 2022
Alternative cementitious materials (ACMs) may exhibit superior mechanical properties and durability to certain environments, and that also may be produced with relatively less environmental impact compared to traditional portland cement.

Influence of deflocculants on the cement hydrate phase formation and technological properties of CAC-bonded castables during the first heating process

open access: yesOpen Ceramics, 2023
The mechanism of growth and decomposition of calcium aluminate cement hydrate phases (CAH phases), which determine the drying behaviour of calcium aluminate bonded castables are not well understood.

A Scanning Transmission X-ray Microscopy Study of Cubic and Orthorhombic C₃A and Their Hydration Products in the Presence of Gypsum. [PDF]

open access: yes, 2016
This paper shows the microstructural differences and phase characterization of pure phases and hydrated products of the cubic and orthorhombic (Na-doped) polymorphs of tricalcium aluminate (C₃A), which are commonly found in traditional Portland cements ...

Calorimetric study of geopolymer binders based on natural pozzolan [PDF]

open access: yes, 2017
This paper investigates the kinetics of geopolymerisation in an inorganic polymeric binder based on a natural pozzolan. The heat released by the exothermic geopolymerisation reaction process is monitored under isothermal temperature conditions ...
