  • Carbonation of concrete

    Carbonation is a slow and continuous process that progresses from the outer surface moving inwards. Over the lifecycle of concrete, carbonation will result in the reabsorption of around a third of the CO2 emitted when making cement, significantly reducing the whole-life CO2 footprint of both the cement and the concrete for which it is used.

  • Siliceous Vs. Carbonate Concrete Hunker

    The strength of carbonate concrete tends to be greater than that of siliceous concrete when both are subjected to extreme heat. The Portland Cement Association indicates that the strength of siliceous concrete begins to wane at about 800 degrees F and its strength is cut by more than half once it reaches a temperature of 1,200 degrees F. Carbonate concrete will retain most of its strength all

  • Carbonate vs. siliceous aggregate Concrete Engineering

    Feb 24, 2004· Carbonate aggregates are generally from sedimentary rock formations. On the side of a core, look at the exposed coarse aggregate. Scratch it with the point of a pocket knife blade. If it scratches without gouging, it is relatively hard and is more likely to be a siliceous material. Carbonate aggregates will gouge under knifepoint.

  • FAQs Pete Lien

    Limestone is calcium carbonate mined from the ground and crushed for various end uses. When high calcium limestone is burned or calcined in a lime kiln, quicklime (calcium oxide) is produced. Quicklime can then be reacted with water to produce hydrated lime (calcium hydroxide). Quicklime has a much higher available calcium carbonate equivalent
