Carbonation resistance of fly ash concrete

, 2015
Based on systematic analysis, evaluation and synthesis of a 30 000 strong data matrix generated from 213 studies from 33 countries published since 1968, this paper details the extent of research that has been undertaken and discusses the effect of fly ...

Climate conditions on the South‐Iberian Palaeomargin during the latest Pliensbachian to early Toarcian: A mineralogical and geochemical study from hemipelagic deposits

Sedimentology, EarlyView.
ABSTRACT The integrated analysis of lithofacies, mineralogy and geochemistry of the hemipelagic marine succession exposed in La Cerradura section (South‐Iberian Palaeomargin) provides new information to characterise the palaeoenvironmental conditions during the latest Pliensbachian to early Toarcian, including the Jenkyns Event.

Mid‐infrared spectroscopy applied to a multi‐level cave system (Montmaurin, SW France): An innovative method for assessing sediment provenance

Sedimentology, EarlyView.
ABSTRACT Deciphering sediment provenance is essential to understand depositional patterns and dynamics. This question is particularly important in archaeological contexts to constrain the sedimentological history of unearthed material—an information critically needed, for example, to estimate the age of the deposits—or to apprehend sediment movement ...

Spatial and temporal evolution of a coastal erg margin: the Middle Jurassic Page Sandstone, southern Utah, USA

Sedimentology, EarlyView.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...

Insect‐resistant soybean genotypes accumulate rutin and its O‐methylated derivative narcissin, a more potent flavonol targeting Anticarsia gemmatalis digestive and detoxification enzymes and reducing larval survival

Journal of the Science of Food and Agriculture, Volume 106, Issue 10, Page 5921-5933, 15 August 2026.
Abstract BACKGROUND Soybean underpins Brazil's agricultural, yet its sustainability is threatened by lepidopteran pests such as Anticarsia gemmatalis. Although insect‐resistant cultivars have long been associated with the constitutive accumulation of quercetin‐derived flavonols, the biochemical mechanisms underlying this resistance remain poorly ...

Optimization analysis of a coupled carbonation-moisture transport model using COMSOL

Case Studies in Construction Materials
Concrete porosity, surface microcracks, and material properties significantly influence carbon dioxide diffusion, leading to inconsistent carbonation depths even under identical mix proportions or environmental conditions.

Economic Assessment of Ocean Alkalinity Enhancement Through Electrodialysis: The Role of Carbon Credits in Comparing Solar Energy and Thermal Waste Technologies

Advanced Sustainable Systems, Volume 10, Issue 6, June 2026.
This study evaluates the economic feasibility of an Ocean Alkalinity Enhancement (OAE) plant with an annual CO2 removal capacity of 878 tonnes. The project is profitable only under scenarios with high carbon credit prices, while medium and low‐price scenarios yield a negative net present value.

A review on carbonation in cement composites and its impacts on durability and potential for CO₂ sequestration

Journal of Materials and Engineering Structures
Carbonation is a key process affecting the durability, strength, and environmental impact of concrete. While it refines pore structure and enhances strength, it also lowers alkalinity, leading to reinforcement corrosion risks.
