SmartCrusher 0-2 versus Norm sand Strength development Smart Crusher sand and cement.
Published April 3, 2016 In November 2014 mortar tests have been carried out in cooperation with / at a concrete-products company regarding 0-2 mm material (sand and cement fractions), obtained by using the SmartCrushing technique from concrete aggregates of concrete paving stones. This 0-2 mm material (in a way SmartCrusher sand) has been compared with (pure) Norm sand 0-2mm.

In the section publications the report on the comparison can be found.

CyBe SmartCrusher bv and CyBe bv are discussing a cooperation based on “Cooperation without limitation”.
Published June 28, 2015 The underlying motivation for SmartCrusher bv is that, on its own, SmartCrusher bv can make the chain of “only” half of all the new concrete circular and, as a result, climate neutral (the prognosis for the quantity of new concrete required is roughly twice the projected quantity of concrete rubble being released). To accelerate closing the concrete cycle completely and reducing CO2 emissions in the process, a different way of concrete construction is required. This means that it must be possible in concrete construction to realise the same quality and quantity of constructions by using substantially less new concrete. As 3D concrete printing is in many respects one of the promising and innovative technologies to this end, SmartCrusher bv is keen to contribute to this. To learn more about 3D concrete printing, please visit www.cybe.eu.

Op On page 7 - table 1 under number 8 the SmartCrusher is mentioned. Page 21 - table 3 shows that with the SmartCrusher technique a reduction potential of 1440 kton/year CO2 and cost reduction of minus €101,- per ton CO2 are possible.

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 TU Delft report mainly describes the economic differences between C2CA TU Delft and the SmartCrusher technique from SmartCrusher BV. On page 29, these differences are graphically presented to provide an easy overview.

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.

This BETONIEK in Figure 4 on page 4 nicely shows how much unused cement can be obtained from concrete debris.

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.
