Single-parameter concrete carbonation model for varying environmental exposure conditions

Carbonation-induced reinforced steel concrete corrosion is a prominent concern related to engineering design and maintenance. The Durability Index (DI) approach was developed in South Africa to address this concern and enhance the durability performance ...

Carbonation of High Strength Concrete

, 2011
High strength concrete consisting of binary and ternary blended cementitious systems based on ordinary Portland cement, pulverised fuel ash and silica fume were investigated for carbonation. PFA up to 40% was used and to these blends 0, 5, 10, and 15% SF

models for modeling of chloride ion ingress and concrete carbonation: Levels of assessment of input parameters

, 2020
Degradation processes affecting structural materials, such as chloride ion ingress, concrete carbonation, and the subsequent corrosion of reinforcement, are limiting factors for the service life of reinforced concrete structures and/or structural ...

Optimizing feather hydrolysate via machine learning for microbial recycling of waste concrete fines

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The concrete industry faces significant challenges from CO2 emissions and the disposal of waste concrete fines (WCF). Microbially induced calcite precipitation (MICP) can bind WCF into bioconcrete, but the high cost of commercial culture media hinders its application.

Resistance of blended concrete containing an industrial petrochemical residue to chloride ion penetration and carbonation [PDF]

, 2014
In this study, the resistance of blended concrete containing catalytic cracking residue (FCC) to chloride ion penetration and carbonation was examined. FCC was added at the levels of 10%, 20%, and 30% as partial replacement for cement. Concretes with 10%

One Hundred Years of the German Soil Science Society (DBG) 1926–2026: Origins, Facts, and Background of an Eventful History

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT On its 100th anniversary in 2026, the German Soil Science Society (DBG) is looking back not only on an eventful history with traditions and impressive achievements but also with painful interruptions and ruptures. One curious fact is that the DBG was initially founded as the national section of the International Soil Science Society (ISSS ...

Carbonation Depth Model and Prediction of Hybrid Fiber Fly Ash Concrete

Advances in Civil Engineering, 2020
The concrete is weakly alkaline, the alkalinity of the concrete will be reduced after being carbonized, and the protective effect of the concrete on the steel bar will be weakened, even leading to corrosion of the steel bar.
