Carbonation behaviour of concrete considering the constituents of coarse aggregate

Tạp chí Khoa học và Công nghệ
This study investigates the carbonation behavior of recycled aggregate concrete (RAC) considering the constituents of coarse aggregate (CA). Coarse natural aggregate (CNA) was replaced with coarse recycled aggregate (CRA) at 0%, 20%, 40%, 60%, 80%, and ...

Accelerated carbonate weathering by immobilized recombinant carbonic anhydrase

Journal of CO2 Utilization
CO2 absorption in aqueous alkaline solutions promoted by carbonic anhydrase (CA) has received increased attention as a solution for post-combustion CO2 capture. In particular, accelerated weathering has emerged as an alternative approach for CO2 capture, mimicking nature’s way to sequestrate CO2. In this study, an evolved CA from Desulfovibrio vulgaris

Reliability-Based Analysis of Recycled Aggregate Concrete under Carbonation

Advances in Civil Engineering, 2018
Durability represents a crucial issue for evaluating safety and serviceability of reinforced concrete structures. Many studies have already focused on carbonation-induced corrosion of natural aggregate concrete (NAC) structures, leading to several ...

Accelerated carbonation test of concrete

, 2021
Embedded steel in reinforced concrete members is protected from corrosion by alkaline composition of the concrete which is provided mainly by the dissolution in the pore water of the Ca(OH)2. However, this positive property of the concrete may be lost in time due to carbonation of hydrated components of cement especially, Ca(OH)2 which is converted to ...

Impact of carbonation and fiber hornification on the performance of fiber-cements

Low-Carbon Materials and Green Construction
The present study evaluates the effect and advantages of the combined use of two treatments on fiber-cement composites: 1) accelerated carbonation on the cement matrix and 2) hornification of commercially used unbleached pine pulp (Pinus radiata D. Don).
