The specifiedpressive strength, cracking strength, and tensile strength of K-UHPC are as high as 180, 9.5 and 13 MPa, respectively. In order to ensure these target strengths, initial curing and high-temperature steam curing are rmended in sequence [].The initial curing is maintained at 20 °C for 12–48 h, with 24 h rmended, immediately after casting.
