Heijmans creates circular concrete circle in Amsterdam
Published on May, 23rd 2022• The Concrete Agreement visits frontrunners from the concrete industry and concrete construction. This time Simone Bel van Betonhuis is present at Heijmans. She examines the pouring of circular concrete at the new underpass at Contactweg in Amsterdam. This project draws the attention of Betonhuis through the application of this innovative circular concrete mixture in a reinforced concrete construction component that separates the road from the cycle path. Betonhuis is working together with the Concrete Agreement to further develop frontrunner stories.

The SmartCrusher 2.0 at work
Published on December, 13th 2021• An impression of the SmartCrusher 2.0 at work. The pre-crushed concrete rubble goes into the SmartCrusher, resulting in the gravel and the sand-cement fraction.

The new SmartCrusher SC 2.0
Published on December, 15th 2020• In close consultation with "launching customer" Fa. Rutte (SCP and Urban Mine) from the Megapool Amsterdam, SmartCrusher BV has put the finishing touches to the SlimBrekers 2 / SmartCrushers 2 (SC2) (or SmartLiberator as it is called at Rutte).

The SC2 is intended to free all fractions from traditional pre-crushed concrete rubble, and that at approximately 40 tons per hour.

After several test runs, the latest SC2 has been found ready for the market!

Betoniek - Reclaiming cement from concrete
Updated December, 9th 2020• We can reuse concrete rubble by granulating and packing it as a sand and gravel substitute. You can also use modern techniques a very fine fraction rich in cement stone recovered. For this fraction to be sustainable and circular applications, ideally as a binder in concrete. The The question here is: can we use cement or a cement substitute make it?

Without mentioning the leader SmartCrusher, we can already answer a few questions; Yes, new reactive binder can be made in the powder phase. This means that it can be done at a much lower temperature and without having to grind.

It is interesting to read that the main cement mineral Aliet C3S is already formed from cement hydrates between 800°C and 900°C. This means that the cement can be made active in the powder phase.

It should be noted that the research, described in this Betoniek, is on recycling of "modern concrete" from after 2000. In contrast to the concrete described in Betoniek March 1983 (in Dutch) nowadays the cement used is much finer ground. Today's cement is more like the cement "pc-B" in Betoniek 1983, fig 4. For this reason the harvested, non-hydrated cement is lower. Fortunately, most concrete rubble is from long before 2000 and, if dried concrete is processed, a lot of "new cement" can be released. And with the rule of thumb: one kg of Portland cement = one kg of CO2, that is a huge difference.

Microwave heating
Published on October, 5th 2018• Re-cementing pure cement hydrates from the SmartCrusher is mainly a matter of heating, and thus a matter of energy. Chemically speaking, hardly anything has changed over the years. From pure cement hydrates this can be done with 30% to 50% less energy compared to CaCO₃ (Marl) and with at least 80 less CO₂ in existing cement kilns.

In the case of fully electrical processing, for example in a number of Microwave furnaces, this can amount to almost CO₂ free new cement! Several Microwave ovens then also form a Gridleveler to match supply and demand of wind and solar energy.
