超(chao)高性(xing)(xing)能(neng)混凝(ning)土，簡稱UHPC(Ultra-High Performance Concrete)，也稱作活(huo)性(xing)(xing)粉末(mo)混凝(ning)土(RPC，Reactive Powder Concrete)，是(shi)過去三十(shi)年(nian)中最(zui)具創新性(xing)(xing)的(de)(de)(de)水(shui)泥基工(gong)(gong)程(cheng)(cheng)材(cai)料，是(shi)實(shi)現(xian)工(gong)(gong)程(cheng)(cheng)材(cai)料性(xing)(xing)能(neng)的(de)(de)(de)大(da)跨(kua)越。UHPC堪稱耐(nai)久性(xing)(xing)最(zui)好的(de)(de)(de)工(gong)(gong)程(cheng)(cheng)材(cai)料，適當配筋的(de)(de)(de)UHPC力學(xue)性(xing)(xing)能(neng)接(jie)近鋼結構，同時UHPC具有優良的(de)(de)(de)耐(nai)磨、抗(kang)爆性(xing)(xing)能(neng)。因此(ci)，UHPC特別適合用(yong)于(yu)大(da)跨(kua)徑橋梁、抗(kang)爆結構(軍(jun)事工(gong)(gong)程(cheng)(cheng)、銀(yin)行(xing)金庫(ku)等(deng)(deng))和(he)薄(bo)壁(bi)結構，以(yi)及(ji)用(yong)在高磨蝕、高腐(fu)蝕環境。目前，UHPC已經在一些實(shi)際工(gong)(gong)程(cheng)(cheng)中應(ying)用(yong)，如風電(dian)混塔、大(da)跨(kua)徑人行(xing)天橋、公路鐵路橋梁、薄(bo)壁(bi)筒(tong)倉、核廢料罐(guan)、鋼索錨固加(jia)強板、ATM機(ji)保護殼等(deng)(deng)等(deng)(deng)。
