Uphando malunga nokuchasana nokugqwala kwekhonkrithi ye-basalt fibre
Ukugqwala kwekhonkrithi yenye yezona zinto ziphambili ezibangela ukuwohloka kokuqina kwekhonkrithi, kwaye iingxaki zokugqwala kwekhonkrithi zibangela ilahleko enkulu kwezoqoqosho minyaka le. Ukuze kuncitshiswe ilahleko kwezoqoqosho ezibangelwa kukugqwala kwekhonkrithi, kubaluleke kakhulu ukufunda ngokumelana nokugqwala kwekhonkrithi. I-Basalt Fiber ikhonkrithi.
Okwangoku, uphando malunga nokumelana nokugqwala kwekhonkrithi yefayibha ye-basalt lubandakanya ukuntywiliselwa kweesampuli zekhonkrithi kwizisombululo ezahlukeneyo zokugqwala kangangexesha elithile kunye nokuhlalutya ukumelana nokugqwala kwekhonkrithi yefayibha ye-basalt ngokusebenzisa iimvavanyo. Izifundo zovavanyo zifumanise ukuba amandla okuxinzelela kunye namandla okugoba kwe ifayibha yebasalt ukwehla kwekhonkrithi njengoko uxinzelelo lwesisombululo esirhabaxa lusanda, kwaye luyancipha ngokwanda kwexesha lokugqwala kwisisombululo esirhabaxa soxinzelelo olufanayo. Ukongezwa kweefayibha ze-basalt kunokuphucula amandla okuxinzelela kunye nokugoba kwekhonkrithi kwindawo erhabaxa. Nangona kunjalo, ukongeza inani eligqithisileyo leefayibha ze-basalt kuya kukhokelela ekunciphiseni amandla okuxinzelela kunye nokugoba kwekhonkrithi. Abanye abaphandi babeke iisampuli zekhonkrithi ze-basalt fiber kwisisombululo se-sodium sulfate kangangeentsuku ezingama-90 kwaye bafumanise ukuba ukongezwa kweefayibha ze-basalt kunokuphucula ngempumelelo ukumelana nokuqhekeka kwekhonkrithi, ngaloo ndlela kwandisa ukumelana kwayo nokugqwala. Phantsi kwezi meko, ukumelana nokuqhekeka okungcono kakhulu kufezekisiwe ngomxholo womthamo wefayibha ye-basalt oyi-0.1%. Kwangaxeshanye, iisampuli zekhonkrithi ze-basalt fiber zafakwa kwisisombululo se-sodium chloride kangangeentsuku ezingama-90, iintsuku ezili-180, kunye neentsuku ezingama-270. Uthelekiso lubonise ukuba ukongezwa kwe imicu ye-basalt inokuthintela uphuhliso lweentanda zakuqala kwikhonkrithi, kwaye njengoko ixesha lokugqwala lisanda, ukumelana kweentanda okungcono kufezekiswa nge ifayibha yebasalt umxholo womthamo we-0.1%. Ukongezwa kobungakanani obufanelekileyo beefayibha ze-basalt kunokunyusa ukumelana kwekhonkrithi nokugqwala okuvela kwi-sodium sulfate kunye ne-sodium chloride. Uvavanyo oluxinzelelweyo kwiisampuli ezifakwe kwisisombululo sokugqwala lufumanise ukuba ukongezwa kwe imicu ye-basalt inokuphucula amandla okuguqulwa kwekhonkrithi kunye namandla okuthwala aphezulu, kwaye isiphumo esihle kakhulu kumthamo wefayibha ye-basalt oyi-0.1%.
Ngamafutshane, ukongezwa kwe imicu ye-basalt inokuphucula ukumelana nokugqwala kwekhonkrithi. Nangona kunjalo, iimvavanyo zangoku zigxile kakhulu kwiimeko zokugqwala (ezifana nokugqwala kwe-sulfate okanye i-chloride), kwaye kufuneka ingxoxo engakumbi yophando malunga nezisombululo ezixutyiweyo zezinto ezimbini okanye ngaphezulu zokugqwala.
