Basalt Fibers Mu Carbonation Resistance ti Nja
I. Mechanism of anti-carbonation action: multi-scale synergistic optimization
1. Pore be ati idinamọ kiraki
Basalt awọn okun ṣe idiwọ awọn dojuijako isunki ṣiṣu ni kutukutu (30% -50% idinku ni iwọn) ati dina awọn ipa ọna kaakiri CO₂ nipasẹ pinpin apapo onisẹpo mẹta. Awọn ọja hydration ipon ti ipilẹṣẹ ni wiwo matrix fiber-matrix le dinku ipin ti awọn pores ipalara (> 100 nm) lati 18.6% si 12.3%, dinku idinku agbara ni pataki.
2. Hydration awose ati Kemikali amuṣiṣẹpọ
Okun dada roughness nse igbega CSH jeli orisirisi awọn iparun, isare awọn hydration lenu, 28 ọjọ hydration ìyí pọ nipa 8% -12%. Nigbati idapọ pẹlu awọn admixtures nkan ti o wa ni erupe ile (fun apẹẹrẹ, fume silica), ipa eeru eeru folkano pọ pẹlu ipa idinku fifọ-fipa dinku porosity lapapọ nipasẹ 40%, ati ipin ti awọn pores ti ko lewu (
II.Engineering iwa ati aje anfani
1. Road aye significantly tesiwaju
Ga-išẹ Okun Basalt idapọmọra nja iwadi ati idagbasoke nipasẹ Yangzhou University, rutting resistance pọ nipa 20% -40%, rirẹ wo inu resistance pọ nipa 2-8 igba, itọju ọmọ tesiwaju lati 3-5 years to 6-8 years, gun-igba itọju iye owo ifowopamọ gidigidi dinku.
2. Imudara iṣẹ ti nja ti a tunlo
Iwadi fihan pe nigba ti nja apapọ ti a tunlo (RAC) ba ti dapọ pẹlu awọn okun basalt 2 kg/m³, ijinle carbonation dinku nipasẹ 41% ni akawe pẹlu kọnkiti ti a tunlo lasan, ati pe resistance carbonation ti o dara julọ jẹ aṣeyọri pẹlu 50% iwọn aropo apapọ atunlo.
III. Awọn aṣa iwaju ati awọn italaya
1. Olona-oko iwadi iwadi
Nilo lati ṣawari siwaju si iṣẹ ṣiṣe igba pipẹ labẹ isọdọkan-iyọ-iyọ-iyọ, data alakoko fihan pe oṣuwọn carbonation ti nja okun labẹ awọn akoko 0.5 fifuye ipari jẹ ṣi 28% kekere.
2. Integration monitoring oye
Gbigbe ti carbonation-sensing fiber opitika ati nẹtiwọọki okun, ipasẹ akoko gidi ti iwaju carbonation (ipe ± 0.1 mm), pese atilẹyin data fun itọju idena.
Basalt okun pese ojutu ipele pupọ fun resistance carbonation nja nipasẹ iṣapeye microstructure ati imudara iṣẹ ṣiṣe Makiro. Pẹlu ilọsiwaju ti eto boṣewa ati imotuntun imọ-ẹrọ, ohun elo rẹ yoo faagun lati awọn opopona ati awọn afara si imọ-ẹrọ omi ati awọn aaye miiran, igbega agbara ti awọn amayederun si akoko tuntun.
