Research on the Cement-Based Smart Lost-Circulation Control Material with Cu-Zn-Al SMA
There were different heat treatments to Cu-Zn-Al shape memory alloy. Cement-based smart lost-circulation control material was prepared by the method of rolling agglomeration. And indoor simulation experiment was carried out. The results show that the heat treatment temperature is 800°C, the quenching medium is the boiling water; the leakage is decreased with the increase of the cotton fiber content. When the cotton fiber content is 4%, the leakage is the minimum; the best volume percent of the lost-circulation control material is 20% in the grout.
