Abstract
The concept of completely recyclable concrete (CRC) has been developed to close the loop. By adequately incorporating limestone aggregates and industrial by-products, the chemical composition should resemble the composiation of Portland clinker which enables the use of CRC as a raw material in Portland cement production. This paper investigates whether the chemical composition can be adjusted by partially replacing cement with pozzolanic fly ash. CRC mixtures were produced with 50 % ordinary Portland cement or blast-furnace cement. At the age of one month laboratory clinker and cement were produced from the CRCs. The resulting cement has a low compressive strength and hydraulic reactivity caused by a high belite content, so corrections were necessary. It is concluded that this paper that cement with hydraulic properties can be produced from CRC, but the chemical composition of all used concrete materials needs to be known for recycling without modification.
