Behavior of calcium aluminate cement (CAC) in the presence of hexavalent chromium

Cement and Concrete Composites, 2016
Abstract Chromium forms part of numerous processes and its unsafe disposal increases the risk of pollution of soils and aquatic systems, especially hexavalent chromium. This paper deals with the behavior of calcium aluminate cement (CAC) in presence of Cr6+ (0.5, 1.0 and 2.5%) as potassium dichromate (K2Cr2O7). The efficiency of CAC to immobilize Cr6+

Effect of particle size of calcium aluminate cement on volumetric stability and thermal shock resistance of CAC-bonded castables

Journal of Alloys and Compounds, 2019
Abstract The distribution and size of in-situ CA6 is related to CAC particle size in CAC-bonded corundum-based castables and would influence the properties of the castables. In order to investigate the influence of CAC particle size on the properties of CAC-bonded castables, CAC was milled for 2 h to reduce particle sizes.

Strain hardening behaviour of PE fibre reinforced calcium aluminate cement (CAC) – Ground granulated blast furnace (GGBFS) blended mortar

Construction and Building Materials, 2020
Abstract Calcium aluminate cement (CAC) is regarded as an effective protective coating material for concrete sewerage pipes to prevent bacterial induced acid corrosion. However, the conversion process occurred in pure CAC mortar limited its application for structural purpose.
