Investigation of carbonation on the compressive strength development of Portland Limestone Cement (PLC) concrete

Discover Civil Engineering
Portland Limestone Cement (PLC) is increasingly promoted as a low-carbon alternative to Ordinary Portland Cement due to its reduced clinker content and associated environmental benefits.

Deterioration behavior and mechanism of concrete under different exposure conditions of sulfate attack and carbonation

Case Studies in Construction Materials
This study systematically investigated the deterioration behavior of concrete under different erosion patterns, i.e., single sulfate attack, single carbonation, and alternating cycle of sulfate attack and carbonation (alternating cycle).

Experimental and predictive assessment of carbonation behavior in concrete with integrated electronic waste fibers

Next Materials
Electronic waste fibers (E-fibers) are a type of electronic waste that significantly impacts the environment. This study examines the incorporation of E-fibers, at replacement levels of 10 %, 20 %, 30 %, 40 %, and 50 %, into concrete with the aim of ...

Numerical Simulation on Carbonation Depth of Concrete Structures considering Time- and Temperature-Dependent Carbonation Process

Advances in Materials Science and Engineering, 2018
In order to further understand the carbonation process of concrete structures, the time- and temperature-dependent diffusion process of CO2 in concrete is simulated based on the law of the CO2 mass conservation, and a two-dimensional mass transfer ...

Grey Correlation Analysis of Compressive Strength and Neutralization Depth in Fly Ash Concrete Under Acid Rain and Carbonation Environments

Buildings
This study investigated the effects of water-to-binder ratio (W/B), fly ash content, pH value, and SO42− concentration on the neutralization depth and compressive strength of fly ash concrete under acid rain erosion, as well as the influence of W/B ...

Similar Microbial Carbon Limitation with Soil Depth despite Decreasing Carbon Availability

Journal of Microbiology and Biotechnology
Carbon availability regulates the rate of microbial soil organic matter decay and respiration. However, it remains unclear how much carbon is available to microbes, and if soil organic carbon content influences microbial carbon limitation. Here, the Michaelis-Menten parameters (Vmax and km) were employed to estimate available carbon and the degree of ...

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.
