The input at the top of the SC2 in the video shown is traditional pre-crushed concrete rubble with Norwegian granite 4-30 mm of high concrete quality. So an input without crushing sand !! As mentioned earlier, the capacity found is approximately 40 tons per hour.
Aforementioned huge reduction is only possible if the concrete rubble with SmartCrusher released cement hydrate new Sulpho calcium aluminate (No. 3) cement is processed. Without SmartCrusher released materials but manufactured from new marl, Sulpho Calcium aluminate cements (No. 3) only score a reduction of 600Kton / year (versus 1440kton / year with SmartCrusher).
This report assumes that all the cement in concrete rubble finished reacting (hydrated) which is proved not so. If this was taken into account then both economic and ecological benefits could have been twice as much.
The CO2 reduction costs will increase with €101,- per ton! This winning combination is completely omitted in subsequent CE Delft report, probably under the influence of the "traditional market".
The reported time table (until 2050) is almost entirely driven by C2CA. The forecast is that in 2016 the SmartCrusher is operational. The prognosis is that it is autonomous operational in 2019.
If back then the concrete rubble was created with a Portland cement A and a water / cement ratio wcf 0.4 then the degree of hydration is up to 60%. Meaning, the SmartCrusher could obtain a minimum of 40% new cement from that concrete rubble.
