Shotcrete system allows mix optimization, shorter cycle times, waste minimization. In one case study, the addition of 3.6 kg/m3 (6.1 lb/yd3) of TYTRO RC 430 allows reducing cementitious content by 33 kg/m3 while achieving equivalent later age strength. Reducing 33 kg/m3 (55.6 lb/yd3) of ordinary Portland cement would result in a reduction of 0.033 metric tonne CO2. If this approach is applied on a middle-size project with a shotcrete production volume of 6500 yd3 (5000 m3), the carbon dioxide emissions of the project would be reduced by 165 metric tons CO2 as a result of reducing the cement content by 7% with the addition of 0.8% of TYTRO RC 430 by total cementitious materials content.
