This paper investigates the mechanical and shrinkage behaviour of concrete with recycled cement (RC) thermoactivated from waste cement paste and waste concrete. Overall, compared to ordinary Portland cement (OPC), for the same water/binder ratio, the mechanical strength and ultrasonic pulse velocity were not significantly influenced by the incorporation of RC. The …

Table 1 shows that as the percentage of ordinary Portland cement in the composite slurry increases (from 10 to 90%), the initial fluidity changes accordingly; after first decrease, it gradually increases. When the proportion of Portland cement reaches 90%, the pumping period could reach 28 min. The initial setting time and the final setting time also tend …

(2) A quadratic model for the minislump of the cement pastes mixed with Na-Mnt was developed statistically. The optimal conditions for ct-PCE dispersion performance in Na-Mnt-incorporated cement paste were a side-chain ratio ((AA + AM):APEG) of 4:9, a monomer ratio (AA:AM) of 9:8, an initiator dosage of 2.9% and a synthesis temperature of 81°C.

Another two patents in 1976 and 1977 succeeded to reduce the cement content less than 3% by using dispersants such as sodium tripolyphosphate in amounts (0.01–0.05 wt.%) and fine matrix, . They replaced part of the cement with sub-micrometer particles ranging from 0.1 to 0.01 μm which could easily be dispersed without forming a gel or a sol.
