Cements based on kaolinite waste [PDF]

, 2018
The cement industry involves high-energy consumption that generates high CO2 emissions into the atmosphere. Environmental concerns can be addressed by replacing parts of Portland cement clinkers with pozzolanic materials in mortars and concrete.

Significance of fineness of pozzolans in determining pozzolanic reactivity

CEMENT
This paper presents the quantification of the pozzolanic reactivity of pozzolans examined in terms of compressive strength, bound water and electrical resistivity. The pozzolans studied included natural pozzolans, glass pozzolans and fly ash that were ground to four fineness levels or median particle sizes (d50) of approximately 3, 5, 10 and 15 µm ...

Transformation of a Silicate Material for Carbon Negative Magnesia‐Based Cement via Electrochemistry

Advanced Science, Volume 12, Issue 42, November 13, 2025.
The transformation of a magnesium trisilicate material via water electrolysis into precursor phases necessary for magnesium‐based M‐S‐H cement is explored. The dissolution of the material mediated electrochemically is monitored, and the analysis of the resulting phases indicate their suitability as effective precursors for M‐S‐H cement.

Thermally treated granite slurry waste as a mitigating agent for sisal fiber mineralization in fiber‐cement composites

International Journal of Applied Ceramic Technology, Volume 22, Issue 5, September/October 2025.
Abstract This study explores the use of thermally treated granite slurry waste to mitigate the mineralization of sisal fibers in fiber‐cement composites. Granite waste was thermally treated at 600°C and 900°C, and the treated materials were analyzed using X‐ray fluorescence (XRF), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric ...

Nano‐Pozzolanic Reaction Empowering Sustainable Construction with Hydrogel

Advanced Sustainable Systems, Volume 9, Issue 6, June 2025.
Nanoclay (NC) hydrogel can provide multifunctionality to building structures by chemically bonding to the surface of cement materials without the need for special adhesives or supports. This study shows that cement structures with attached NC hydrogel exhibit excellent thermal insulation effects and support successful plant growth.

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.
