Investigating the feasibility of producing sustainable and compatible binder using marble waste, fly ash, and rice husk ash: A comprehensive research for material characteristics and production

Results in Engineering, 2023
This research aims to develop a new marble-based binding material for evaluating its strength blended with rise husk ash and fly ash. Newly developed marble-based cement was prepared by burning waste marble powder and clay.

THE EFFECT OF GROUND GLASS WASTE ON PROPERTIES OF HARDENED CEMENT PASTE AND MORTAR

Ceramics-Silikáty, 2020
The article addresses the effect of finely ground waste glass on the properties of hardened cement paste and mortar. Cement mixtures were formulated by replacing 0 %, 5 %, 10 %, 15 %, 20 %, 25 %, and 30 % of cement with ground waste glass.

Damage Localisation in Fresh Cement Mortar Observed via In Situ (Timelapse) X-ray μCT imaging [PDF]

Cement and Concrete Composites, 2024, 154, 105736, ISSN 0958-9465
This paper presents the outcome of a study focused on the evolution of internal damage in fresh cement mortar over 25 hours of hardening. In situ timelapse X-ray computed micro-tomography ({\mu}XCT) imaging method was used to detect internal damage and capture its evolution in cement mortar hardening.

On Slow Dynamic Elasticity at short times [PDF]

arXiv, 2023
It has been reported that slow dynamic nonlinear elastic relaxations, widely thought to proceed in proportion to the logarithm of time since mechanical conditioning ceases, recover at a diminished rate at early times, with a time of transition that varies with the grain size of the material.

Silicosarcoidosis: Histologic and Clinical Features of an Occupational Granulomatous Disease

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Sarcoidosis is a multisystem inflammatory disease of unknown etiology. Growing evidence indicates that occupational exposure to respirable crystalline silica (RCS) is associated with an increased incidence of sarcoidosis. Yet a diagnosis of sarcoidosis rarely prompts investigation to identify preventable exposures.

Sustainable Pathways for the Synthesis of Calcium Sulfate Hemihydrate

Angewandte Chemie International Edition, EarlyView.
Calcium sulfate hemihydrate (bassanite) plays a key role in construction as a hydraulic binder. Due to its instability in water, industrial production primarily relies on thermal dehydration of gypsum. This review examines alternative, potentially more sustainable methods for the synthesis of bassanite, including gypsum conversion at lower temperatures
