This paper studied the influence of cooling regimes on the residual mechanical properties of ECC (Engineered Cementitious Composites) after high temperatures. The ECC specimens were heated to different temperatures (200, 400, 600 and 800 ℃) and cooled in different regimes (cooling in air and quenching in water). The residual mechanical properties were tested. The results indicated that the specimens quenching in water gained better mechanical properties than the one cooling in air and the influence of cooling regimes increased with temperature. The micro structural characterization was examined before and after exposure to fire deterioration by using scanning electron microscopy (SEM) and mercury intrusion porosimetry (MIP) test. The results from the micro test explained the mechanical property variation of post-fire specimens.
