Abstract
The disclosure provides a method and a system for processing concrete granulate for subsequent recycling of the concrete granulate. In the method, a container of the system is filled with concrete granulate, said container being gas-tight at least in some regions. Subsequently, gas comprising CO2 is fed, continuously or noncontinously, according to a level of CO2 absorption by the concrete granulate in the container, said level being determined by means of at least one sensor. After a predefined CO2 saturation of the concrete granulate has been detected, the concrete granulate, which have been enriched with CO2, are removed.
Claims20
A method for processing concrete granulate for subsequent recycling of the concrete granulate, comprising the following method steps:
- a. Filling an at least partially gas-tight container with concrete granulate;
- b. Supplying a volume flow of gas comprising CO2 into the container as a function of a measure of an occurred CO2 absorption by the concrete granulate in the container, the measure of the occurred CO2 absorption being determined via at least one sensor;
- c. Determining whether a predefined CO2 saturation of the concrete granulate has been reached and, if not, continuing with method step b;
- and
- d. In response to a determination that the predefined CO2 saturation of the concrete granulate has been reached, removing the concrete granulate enriched with CO2 for use in producing recycled concrete.
