UHPC A Method For Producing UHPC Through Curing In Water And UHPC Manufactured Through Curing In Water
The present invention relates to a method for producing ultra-high performance concrete (UHPC). The method comprises the steps of: mixing cement, a mineral admixture, silica sand, and silica sand powder in a batch without water; adding a chemical admixture and water to the batch and mixing the same for 3-5 minutes; compressing the mixture in the batch at 20-40 MPa; curing the compressed mixture in the batch for 18-36 hours; transferring the cured mixture in the batch to an aquatic curing space; and performing underwater-accelerated curing on the batch mixture in curing water at a set temperature in the aquatic curing space, wherein the cement is contained in an amount of 100 parts by weight, the mineral admixture is contained in an amount of 30 parts by weight, the silica sand is contained in an amount of 110 parts by weight, the silica sand powder is contained in an amount of 39 parts by weight, the chemical admixture is contained in an amount of 2 parts by weight, and the water is contained in an amount of 25 parts by weight, and the set temperature is in the range of 180-210 ℃. According to the present invention, it is possible to quickly provide concrete with desired physical properties.
