Carbonation of fly ash concrete

Magazine of Concrete Research, 1992
The carbonation of fly ash concrete is reported, with particular emphasis on the role of curing. Concretes with nominal strength grades C25, C35 and C45 and a range of fly ash levels (0–50%) were exposed to various treatments during the first 28 days; i.e.

Carbonation of concretes in the Mexican Gulf

Building and Environment, 2000
Abstract Carbon dioxide penetration into concrete leads to reinforcing depassivation and onset of the corrosion process. Thus, a deep knowledge on the parameters affecting such a process will allow definition of the most suitable mixture design to provide adequate durability.

Mechanical properties of carbonated concrete

Journal of the Chinese Institute of Engineers, 2003
Abstract In this paper, mechanical properties of carbonated concrete were studied. Com‐pressive strength, splitting tensile strength, elastic modulus, bond strength and hardness for carbonated concrete subjected to various carbonation conditions were evaluated.

Concrete carbonation in arid climate

Materials and Structures, 2002
Fifty-four different concrete mixes were exposed to hot arid weather in Kuwait to monitor their extent of carbonation. Various parameters affecting carbonation such as water/cement ratio, cement content, type of cement, type and dosage of admixture, water-curing period, type of coating, and the addition of silica fume or pulverized fuel ash were ...

Re-alkalisation of carbonated concrete — Effect on concrete properties

Construction and Building Materials, 1997
Abstract Electrochemical re-alkalisation of concrete involves application of a direct current between an externally applied anode surrounded in a sodium carbonate electrolyte and the internal reinforcing steel. It offers a means of rehabilitating reinforced concrete in which carbonation has progressed so far that the steel is at risk of corrosion ...

Concrete with Accelerated Naturally Carbonated Recycled Concrete Aggregates

Journal of Materials and Polymer Science
Recycled concrete tends to be increasingly investigated with respect to the environmental needs, such as resource depletion, circularity and lack of landfill disposal spaces. A naturally accelerated carbonation procedure by using atmospheric CO2 concentration level and a cyclic wetting and drying of the recycled concrete aggregates was applied.
