Possibilities of using the ultrasonic wave transmission method to estimate initial setting time of cement paste [PDF]
, 2008 In this paper, the applicability of the ultrasonic wave transmission method to estimate the initial setting time of an arbitrary cement paste is discussed. Ultrasonic pulse velocity measurements were fully automated and measured continuously.

Modifying admixtures to cement compositions produced from local raw materials
MATEC Web of Conferences, 2018 Durability of hardened cement paste depends on chemical and mineralogical composition of Portland cement. The main factor for hardened cement paste is higher content of calcium aluminate and free calcium hydroxide, binding of which into water-insoluble ...

Solidification/stabilisation of soil contaminated with metal: a review [PDF]
, 2008 Solidification/stabilisation (S/S) is generically defined as a chemical and physical alteration technique of reducing the mobility as well as solubility of contaminants in wastes in order to convert them into chemically inert form.

Reduction of water content in calcium aluminate cement with/out phosphate modification for alternative cementation technique [PDF]
, 2018 Cementation of the secondary aqueous wastes from TEPCO Fukushima Daiichi Nuclear Power Plant is challenging due to the significant strontium content and radioactivity, leading to a potential risk of hydrogen gas generation via radiolysis of water content.

Engineering Reports, Volume 8, Issue 4, April 2026.Barley husk ash (BHA), an agricultural byproduct rich in pozzolanic oxides, was optimized as a sustainable cement substitute. Statistical modeling and experimental validation confirmed 22.75% BHA as the optimal replacement, enhancing mechanical and durability performance while advancing eco‐efficient construction practices.

Spinel Aluminate‐Based Heterojunctions as Photocatalyst: A Review
ChemistryOpen, Volume 15, Issue 4, April 2026.Spinel aluminates (MAl2O4; M = Zn, Mg, Ca, Sr) serve as robust platforms for designing heterojunction photocatalysts. Their stable lattices, tunable band structures, and efficient charge transport enable improved light‐driven carrier separation, significantly enhancing pollutant degradation efficiency in advanced photocatalytic systems.

Phase evolution behaviour of dolomite-alumina system [PDF]
, 2014 Magnesium Aluminate Spinel Refractories are usually prepared by sintering from Calcium Aluminate Cement and Synthetic Mag-Al spinel. But the high cost of electrofused or sintered spinels is a hindrance and hence a suitable alternative is required ...
