Uphando kwi-Corrosion Resistance ye-Basalt Fiber Concrete
Ukonakala kwekhonkrithi ngomnye woonobangela bokuwohloka kokuqina kwekhonkrithi, kwaye imiba yokonakala kwekhonkrithi ibangela ilahleko enkulu yezoqoqosho minyaka le. Ukunciphisa ilahleko yezoqoqosho ebangelwa kukuhlwa kwekhonkrithi, kubaluleke kakhulu ukufunda ukumelana nokudleka kwe-corrosion. IFayibha yeBasalt ikhonkrithi.
Okwangoku, uphando malunga nokuxhathisa ukubola kwekhonkrithi ye-basalt fiber ikakhulu kubandakanya ukuntywiliselwa kwesampulu zekhonkrithi kwizisombululo ezahlukeneyo zomhlwa kangangexesha elithile kunye nokuhlalutya ukuxhathisa kokubola kwekhonkrithi ye-basalt fiber ngokusebenzisa imifuniselo. Izifundo zovavanyo zifumene ukuba amandla oxinzelelo kunye namandla okuguquguquka kwe i-basalt fiber ukuhla kwekhonkrithi njengoko uxinaniso lwesisombululo esonakalisayo sanda, kwaye ziphinda zehla ngokunyuka kwexesha lokutya kwisisombululo esonakalisayo soxinaniso olufanayo. Ukongezwa kwe-basalt fibers kunokuphucula amandla okunyamezela kunye ne-flexural yekhonkrithi kwindawo engcolileyo. Nangona kunjalo, ukongeza inani eligqithisileyo lemicu ye-basalt iya kukhokelela ekunciphiseni kokuqina kwekhonkrithi kunye namandla okuguquguquka. Abanye abaphandi baye babeka iisampulu zekhonkrithi ye-basalt kwisisombululo se-sodium sulfate iintsuku ezingama-90 kwaye bafumanisa ukuba ukongezwa kwe-basalt fibers kunokuphucula ngokufanelekileyo ukuxhathisa ukuqhekeka kwekhonkrithi, ngaloo ndlela kwandisa ukuxhathisa ukubola. Ngaphantsi kwezi meko, ukuchasana kokuqhekeka okugqwesileyo kwafunyanwa ngomthamo we-basalt fiber volume ye-0.1%. Ngelo xesha, iisampuli zekhonkrithi ze-basalt zafakwa kwisisombululo se-sodium chloride iintsuku ezingama-90, iintsuku ezingama-180 kunye neentsuku ezingama-270. Uthelekiso lubonise ukuba ukongezwa kwe imicu yebasalt inokuthintela uphuhliso lweentanda zakwangoko kwikhonkrithi, kwaye njengoko ixesha lokukhula lisanda, okona kuxhathisa ukuqhekeka kuphunyezwa nge i-basalt fiber isiqulatho somthamo we-0.1%. Ukongezwa kwesixa esifanelekileyo se-basalt fibers kunokonyusa ukuxhathisa kwekhonkrithi kwi-corrosion kwi-sodium sulfate kunye ne-sodium chloride. Iimvavanyo ezicinezelayo kwiisampulu ezifakwe kwisisombululo esonakalisayo zifumene ukuba ukongezwa kwe imicu yebasalt inokuphucula umthamo we-concrete deformation kunye nomthamo wokugqibela wokuthwala, kunye nefuthe elihle kakhulu kumxholo we-basalt fiber volume ye-0.1%.
Isishwankathelo, ukongezwa kwe imicu yebasalt inokuphucula ukuxhathisa kwe-corrosion yekhonkrithi. Nangona kunjalo, imifuniselo yangoku igxile ikakhulu kwiimeko zokubola (ezifana ne-sulfate okanye i-chloride corrosion), kunye nengxoxo eyongezelelweyo iyafuneka kuphando lwezisombululo ezixubeneyo zezinto ezimbini okanye ngaphezulu ezonakalisayo.
