Effect of the colloidal zirconia on corrosion resistance of low-cemented alumina mixes against steel slag

Journal of Asian Ceramic Societies, 2021
The corrosion resistance of the low-cement alumina base refractory against the slag of the electric arc furnace using zirconia was studied. Colloidal zirconia was replaced at the expense of the calcium aluminate cement by 1, 2, and 4 wt.% (C1, C2, and C4)

Porous Bioglass Scaffold for Orthopedics Applications

Medžiagotyra, 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

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

, 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 ...

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

, 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 ...

Designing corrosion resistant systems with alternative cementitious materials

Cement, 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 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.

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

, 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 ...

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

, 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.
