A review of accelerated carbonation technology in the treatment of cement-based materials and sequestration of CO2

FERNANDEZBERTOS, M, SIMONS, S, HILLS, C, CAREY, P·2004·Journal of Hazardous Materials

Abstract

Moist calcium silicate minerals are known to readily react with carbon dioxide (CO2). The reaction products can cause rapid hardening and result in the production of monolithic materials. Today, accelerated carbonation is a developing technology, which may have potential for the treatment of wastes and contaminated soils and for the sequestration of CO2, an important greenhouse gas. This paper reviews recent developments in this emerging technology and provides information on the parameters that control the process. The effects of the accelerated carbonation reaction on the solid phase are discussed and future potential applications of this technology are also considered.

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • For dry carbonation of cement-based composites, a slight positive pressure of CO2 seems desirable.

    “Therefore, for dry carbonation of cement-based composites, a slight positive pressure of CO 2 seems to be desirable [31,54].”
  • Too high moisture content prevents CO2 from penetrating into the inner part of samples, compromising CO2 diffusion and overall carbonation effect.

    “It is believed that too high moisture content prevents CO 2 from penetrating into the inner part of samples [31,87,91,94,95], therefore compromising CO 2 diffusion and overall carbonation effect.”
  • RM is generally carbonated via a direct process route at ambient temperatures and pressures and a sequestration capacity of 0.04-0.05 tCO2 per t RM has been reported.

    “RM is generally carbonated via a direct process route at ambient temperatures and pressures 162,166,167 and a sequestration capacity of 0.04-0.05tCO 2 per t RM has been reported (Table 5).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
