Table 6 Performance of concrete under a no climate change scenario.
No climate change | Design strength (MPa) | Real strength (MPa) | Slump (mm) | Carbonation depth (mm) | CO2 emissions from materials (kg/m3) | CO2 uptake (kg/m3) | Net CO2 emissions (kg/m3) | CO2 uptake ratio |
|---|---|---|---|---|---|---|---|---|
Mix1: design strength of 25Â MPa | 25.00 | 35.45 | 177.73 | 30.00 | 118.82 | 14.36 | 104.46 | 0.121 |
Mix2: design strength of 35Â MPa | 35.00 | 35.45 | 177.73 | 30.00 | 118.82 | 14.36 | 104.46 | 0.121 |
Mix3: design strength of 45Â MPa | 45.00 | 45.00 | 197.96 | 23.46 | 145.05 | 12.37 | 132.69 | 0.085 |
Mix4: design strength of 55Â MPa | 55.00 | 55.00 | 217.84 | 17.39 | 178.63 | 10.33 | 168.30 | 0.058 |
