Engineering statistical models for carbonation depth

European Journal of Environmental and Civil Engineering, 2022
Based on generalized linear models and gamma degradation processes, two models predicting the natural carbonation of reinforced concrete (R.C) structures are proposed. They include the main factors influencing the carbonation process (material, environmental and curing factors) and their effects are evaluated from a large sample of natural carbonation ...

Depth profiles of carbonates formed during natural carbonation

Cement and Concrete Research, 2002
Abstract The depth profiling of carbonates formed during a natural carbonation of mortars with one face exposed directly to rain and the opposite face sheltered have been measured. The amount of carbonates formed on mortars sheltered from rain is generally higher.

Carbonate Compensation Depth: Relation to Carbonate Solubility in Ocean Waters

Science, 1974
In situ calcium carbonate saturometry measurements suggest that the intermediate water masses of the central Pacific Ocean are close to saturation with respect to both calcite and local carbonate sediment. The carbonate compensation depth, located at about 3700 meters in this area, appears to represent a depth above which waters are essentially ...

In-depth modifications of implanted amorphous carbon films

Applied Physics A Solids and Surfaces, 1994
Amorphous carbon films (a-C:H) and nitrogen incorporated carbon films [a-C:H(N)] deposited by a self-bias glow discharge have been implanted with 70 keV nitrogen ions at fluences of 0.6, 1 and 2×1017 N/cm2. The in-depth modifications caused by ion implantation were determined by means of nuclear techniques, such as Rutherford Backscattering ...

Pore Structural Changes and Carbonated Depth of Carbonated Steel Slag

Advanced Materials Research, 2011
Steel slag and carbon dioxide were used as raw materials to prepare building material by carbonation. Effects of forming pressure on carbonation of steel slag and carbonated depth were studied by pore structural changes before and after carbonation and carbonated region.
