Table 9.
Determination of energy consumption and CO2 emissions for 1 m3 of fibre concrete with RSF fibres.
| Concrete Component | Energy Consumption Factor (MJ/kg] | CO2 Emission (kg CO2/kg] |
Amount in 1 m3 (kg] | Energy Consumption (MJ] | CO2 Emission (kg CO2] |
|---|---|---|---|---|---|
| cement (kg] | 3 * | 0.3 ** | 320 | 960 | 96 |
| water (dm3] | 0.05 ** | 0 ** | 160 | 8 | 0 |
| sand 0/2 (kg] | 0.1 ** | 0.007 ** | 801 | 80.1 | 5.607 |
| gravel 2/8 (kg] | 0.1 ** | 0.007 ** | 681 | 68.1 | 4.767 |
| gravel 8/16 (kg] | 0.1 ** | 0.007 ** | 454 | 45.4 | 3.178 |
| fibre RSF (kg] | 0 **** | 0 **** | 50 | 0 | 0 |
| SUMA |
1161.6 (MJ] |
109.55 (kg CO2] |
(*)–(**) according to Table 8. (****) zero energy consumption and zero CO2 emission value were assumed for RSF fibres constituting waste during rubber recovery.
