Modeling of Physical–Chemical and Thermomechanical Properties of Glasses From Recycled Waste

open access: yesInternational Journal of Applied Glass Science, Volume 17, Issue 2, April 2026.
ABSTRACT This research focuses on understanding the high‐temperature phase evolution occurring during the vitrification of heterogeneous construction and demolition wastes (CDWs). The aim of this project is to transform this widely distributed and mostly unused waste stream into a homogeneous, engineered, glass‐based material with predictable ...

Incorporation of Coconut Fibers Into Clay‐Based Mortars: A Study on Mechanical and Microscopic Behavior

open access: yesInternational Journal of Ceramic Engineering &Science, Volume 8, Issue 2, March 2026.
Clay‐based mortar reinforced with coconut fibers showed improved flexural strength and promising mechanical performance, despite shrinkage‐induced cracks. The study highlights the potential of using waste and natural fibers in eco‐efficient mortars, emphasizing the importance of curing and moisture control.

An Ensemble Machine Learning Method for Alkali‐Activated Concrete Mix Ratio Analysis and Optimizing Experimental Results

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
In this study, we discovered a combined learning algorithm of MLP–RF for predicting the composition of concrete and achieved favorable results in the inversion experiment. ABSTRACT In the field of civil engineering, the analysis of the composition of alkali‐sprayed concrete is of great significance for material research. However, there are currently no

The sulphate resistance of the portland cements and their grinding fineness degree: analysis of their relation

open access: yesMateriales de Construccion, 1994
This work has demonstrated the great influence that the specific surface of a Portland cement has on its qualification as a high or low resistance to sulfate ion attack - SIA, by means of the accelerated method ASTM C 452.

Circular Alkali‐Activated Cements Based on EAF Slags and Biomass Bottom Ash Using Rice Husk Ash–Derived Sodium Silicate

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
ABSTRACT This study investigates sodium silicate (SS) solutions derived from rice husk ash (RHA) dissolved in 8 M NaOH as sustainable activators for alkali‐activated cements (AACs), compared with commercial SS. AACs were produced using a 50:50 blend of electric arc furnace slag (EAFS) and biomass bottom ash (BA). The effects of NaOH/RHA ratio (6.6–2.8)

Reactivity Evolution of Mechanochemically Activated Laterite Used as a Supplementary Cementitious Material

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
ABSTRACT The use of laterite soil with high Al and Fe content has been investigated as a novel supplementary cementitious material (SCM) to replace traditional mineral materials for clinker substitution. High‐energy ball milling was used to mechanochemically activate laterite and change its reactivity.

The pyrogenic mediator prostaglandin E2 elicits warmth seeking via EP3 receptor‐expressing parabrachial neurons: a potential mechanism of chills

open access: yesThe Journal of Physiology, Volume 604, Issue 5, Page 2110-2130, 1 March 2026.
Abstract figure legend During infection, prostaglandin E2 (PGE2) is produced and elicits warmth‐seeking behaviour and involuntary febrile responses by acting on prostaglandin EP3 receptors (EP3Rs) in two distinct brain sites. PGE2 acting on EP3Rs on neurons in the external lateral part of the lateral parabrachial nucleus (LPBel) augments cold sensory ...

A comparative study on the clinical success of restorations with MTA and gray Portland cement in permanent molar perforations

open access: yesمجله دانشکده دندانپزشکی اصفهان, 2010
Introduction: A large number of materials have so far been applied to restore tooth perforations. Gray MTA is now the material of choice for such purpose.
