Ifayibha yebasalt eqoshiweyo yi-fiber yeminerali engaphiliyo enobude obungaphantsi kwe-50mm enqunyulwe kwizinto ezisisiseko ze-basalt fiber kwaye ingasasazwa ngokulinganayo kwikhonkrithi. Ngokwendlela esetyenziswa ngayo, ingahlulwa ibe yikhonkrithi ifayibha enganyangekiyo ziintanda (BF), ifayibha yokuqinisa eqinileyo (BZ) kunye nefayibha engaqhekekiyo kwi-mortar (BSF).
Ikhonkrithi yefayibha yebasalt eqoshiweyo yenzelwe ukongeza iifayibha zebasalt ezinqunqiweyo eziqhubekayo okanye ezingashukumiyo kwikhonkrithi ngomlinganiselo ofanelekileyo, nangendlela efanelekileyo, ukuphucula ukuqina kunye namandla okuxinana kwekhonkrithi, ngelixa igcina amandla okuqala okuxinzelela esakhiwo sekhonkrithi, ukuze iqinise ikhonkrithi kwaye yandise ubomi benkonzo yeprojekthi.
Ukubonakala kwefayibha yebasalt eqoshiweyo kugcwalisa umsantsa ngokwezinto ezisetyenziswayo kunye neendlela, kwaye kudlala indima enkulu ekukhuthazeni ukuqina kunye ukuqiniswa kwekhonkrithiIndima yayo ekuqiniseni nasekuqiniseni ikhonkrithi ibonakala kwezi zinto zilandelayo:
(1) Imisonto ye-basalt enqunqiweyo ingayisebenzisa ngokupheleleyo indawo yayo yomphezulu kunye neenzuzo zobungakanani, ukuze ithintele ii-micro-cracks ukuze zingadibani, kwaye iziphumo ziyamangalisa. Kwangaxeshanye, iyoyisa iintsilelo zezinye ii-synthetic fibers ezifana noxinano oluphantsi, amandla aphantsi okutsalwa kunye ne-elastic modulus, njengokutsalwa lula xa ii-cracks zisanda, nto leyo enokuthintela ngempumelelo ukwanda kwee-micro-cracks ezikhoyo kunye nokubonakala kwee-cracks ezintsha. Ukunyibilika, ukungangeni kwamanzi kudlale isiphumo esithile.
(2) Ukongeza ekubeni ifana nefayibha yentsimbi, ifayibha yebasalt eqoshiweyo inokusebenzisa imodulus yayo ephezulu kunye namandla okutsalwa okuphezulu okukodwa ukuthintela ukwanda kwemifantu, kwaye inokuthintela nemifayibha yentsimbi ukuba ibotshelelwe lula ngexesha lokuxukuxa, nto leyo engayilungelanga ipompo. Inkqubo yokwakha iyinkimbinkimbi.
(3) I-basalt fiber eqoshiweyo yi-nitrocellulose eqhelekileyo, enokuhambelana kwendalo, kwaye ngenxa yokuba ifana ngobuninzi nesamente kunye nesamente, ubuninzi buphakathi kwe-2.63-2.8g/m³; ukusebenza kakuhle, ii-basalt fibers eziqoshiweyo zingasasazwa ngokulinganayo emva kokuba zifakwe kwisakhiwo sesamente.
(4) Umphezulu wefayibha ye-basalt eqoshiweyo utshintshiwe, kwaye luhlobo "lwefayibha engasebenziyo", enokumelana okuhle kakhulu nobushushu obuphezulu, ukumelana nokugqwala kunye nokumelana nempembelelo. Ingagcina uzinzo kubushushu obuphezulu kunye nendawo egqwalisayo ephezulu, kwaye inokuphucula ukumelana nokuguquguquka kwe-matrix yesamente. Ke ngoko, ifayibha ye-basalt eqoshiweyo inokuqhelana nendawo engqongo kuzo zonke izigaba zokuxuba, ukuthulula, ukujiya kunye nokusetyenziswa kwesamente, kwaye iphucule ukuqina kwesamente.
