詳細(xì)說明

DJ01公路橋梁預(yù)應(yīng)力孔道壓漿料

DJ-01 公路橋梁預(yù)應(yīng)力孔道壓漿料(簡稱:公路孔道壓漿料)是以優(yōu)質(zhì)水泥與多種有機(jī)和無機(jī)材料復(fù)合而成的壓漿材料。在施工現(xiàn)場按一定比例加水,并攪拌均勻后,用于后張預(yù)應(yīng)力孔道壓漿。產(chǎn)品漿體密實(shí),保護(hù)預(yù)應(yīng)力筋不受腐蝕;粘結(jié)牢固,保證預(yù)應(yīng)力筋與混凝土之間的粘結(jié)力,使預(yù)應(yīng)力有效傳遞。

廣泛適用于后張法預(yù)應(yīng)力橋梁孔道的壓漿施工,帷幕灌漿、錨固灌漿、空隙、空洞填補(bǔ)修復(fù)等領(lǐng)域。執(zhí)行標(biāo)準(zhǔn)《JTG/TF502011

一、產(chǎn)品優(yōu)點(diǎn)

低水膠比:水膠比僅為0.260.28

高流動(dòng)性:漿體的出機(jī)初始流動(dòng)度可達(dá)10S60min后流動(dòng)度仍保持在25S以內(nèi);

高穩(wěn)定性:漿體24h自由泌水率和3h鋼絲間泌水率均為0

高抗分離性:產(chǎn)品滿足歐洲標(biāo)準(zhǔn)ETAG013要求,仿真試驗(yàn)5m管零泌水、無缺陷;

絕濕微膨脹:漿體在預(yù)應(yīng)力孔道內(nèi)絕濕條件下仍能產(chǎn)生膨脹,補(bǔ)償漿體收縮,提高了硬化漿體體積穩(wěn)定性,保證壓漿質(zhì)量;

早強(qiáng)高強(qiáng):3d抗壓強(qiáng)度≥20MPa28d抗壓強(qiáng)度≥50MPa

高耐久性:28d電通量1000C,28d抗凍等級≥F500
