Capturing Carbon's Potential: These Companies Are Turning

May 29, 2019· Montreal-based Carbicrete, an X Prize finalist, is replacing cement with ground steel slag, then curing it with CO2, which becomes a solid and binds the slag granules together into concrete. This technology eliminates the production of 2kg of CO2 per concrete block and injects 1kg of CO into each block, so it is considered carbon negative.

Methods for improving volume stability of steel slag as

Nov 25, 2008· Suitable methods for enhancing the volume stability of steel slag utilized as fine aggregate were determined. The effects of steam treatment at 100 °C and autoclave treatment under 2.0 MPa on the soundness of steel slag sand were investigated by means of powder ratio, linear expansion, compressive and flexural strength. DTA, EDX, XRD and ethylene glycol methods were employed to
