Uhlobo olutsha lwezinto zokuqinisa ikhonkrithi: Iifayibha ze-basalt ezimile okwehinji eziyi-12/35/50-millimeter zifezekisa ukusetyenziswa kwemizi-mveliso

Kwicandelo lezinto zokuqinisa i-concrete, itekhnoloji entsha ibangela utshintsho olukhulu kushishino. Inkampani ephambili yokuvelisa izinto ezintsha kutshanje ibhengeze ukuba imveliso yayo ephambili - efana ne-hinge ifayibha yebasaltenobubanzi obuziimilimitha eziyi-0.7 kunye nobude obuziimilimitha eziyi-12/35/50 - iphumelele kwimveliso yemizi-mveliso. Iya kusetyenziswa ikakhulu kwimveliso ephezulu. Izakhiwo zekhonkrithi, ukusombulula ngempumelelo ingxaki yokuqina kwexesha elide.

Ngokungafaniyo neefayibha zemveli ezigudileyo, olu lwakhiwo lukhethekileyo olufana neehinji I-Basalt FiberI-s inokwenza amanqaku amaninzi okubambelela koomatshini ngaphakathi kwi-matrix yekhonkrithi. Olu yilo luphucula kakhulu ukusebenza kokubopha phakathi kweefacial phakathi kweefacial kunye ne-matrix, kunciphisa kakhulu umngcipheko wokuba iifayibhile zitsalwe phantsi koxinzelelo. Idatha yovavanyo ibonisa ukuba amandla okuxinana kwale fayibha adlula i-1200 megapascals, kwaye i-elastic modulus ifikelela kwi-50 gigapascals. Ingathintela ngempumelelo ukwakheka kunye nokwanda kwee-microcracks ngexesha leplastiki kunye nezigaba zokuqina kwekhonkrithi.

Ngenxa yokuzinza okungokwemvelo kwelitye lentaba-mlilo, olu hlobo lwefayibha lunokumelana okuhle kakhulu ne-alkali, nto leyo eyenza ukuba ikwazi ukugcina ukuzinza kokusebenza ixesha elide kwiindawo ezinzima ezifana nobunjineli baselwandle, umgangatho wemizi-mveliso, kunye neziseko zophuhliso ezinemijikelo yokunyibilikisa rhoqo. Uvavanyo lokuqala lubonisa ukuba ukongeza iikhilogram ezi-3-5 zale fayibha nge-cubic meter nganye yekhonkrithi kunokunciphisa ukuqhekeka kwemifantu ngaphezulu kwama-60% xa kuthelekiswa nekhonkrithi ecacileyo, kwaye kuphindwe kabini ukumelana nokuchaphazeleka.

“Oku akusiyonto yokongeza nje kuphela, kodwa sisisombululo esibanzi sokuphucula esisekelwe kwinkqubo,” utshilo umlawuli we-R&D waseTshayina Beihai. “Ulwakhiwo olukhethekileyo lwejometri lweefayibha ezifana ne-hinge lutshintsha ukusasazwa koxinzelelo ngaphakathi kwikhonkrithi, nto leyo evumela iinjineli ukuba ziyile amacandelo amancinci ezinto, zinciphise ubungakanani bemivalo yokuqinisa, kwaye zandise ubomi besakhiwo.”

Okwangoku, le mveliso isetyenziswe ngempumelelo kwiiprojekthi eziphambili ezifana nodonga lwemijelo eYurophu kunye nokuphuculwa kwamazibuko eMbindi Mpuma. Amandla ayo abalaseleyo okumelana nokugqwala kunye nokulawula iimfanta aqatshelwe kakhulu luluntu lobunjineli. Ukusuka kwimbono yophuhliso oluzinzileyo, ukusetyenziswa kwamandla emveliso imicu ye-basalt iphantsi kakhulu kuneyeefayibha zentsimbi okanye zepolymer. Ngaphezu koko, izinto ezisetyenzisiweyo zininzi kwaye zivela kwindalo, nto leyo ehambelana nomkhwa wophuhliso lwezakhiwo eziluhlaza.

Ukuqaliswa kwale mveliso kuhambelane nexesha elibalulekileyo lokuphucula imigangatho yeshishini lekhonkrithi yehlabathi. Ihambelana ngokupheleleyo neemfuno zemigangatho yekhonkrithi eqiniswe ngefayibha yamazwe ngamazwe, inika iinjineli isixhobo esisebenzayo sokufikelela kwimigangatho ephezulu yokuqina kunye neenjongo zokunciphisa ikhabhoni.

Njengoko imiba yokuguga kweziseko zophuhliso zehlabathi ikhula kwaye iimfuno zophuhliso oluzinzileyo zisanda, ukwamkelwa kwetekhnoloji yekhonkrithi eqinisiweyo ngefayibha ephezulu akuseyonto intsha nje yobugcisa; ikwalukhetho olungenakuphepheka lophuhliso lweshishini. Olu tshintsho lubonisa ukuba isayensi yezinto zekhonkrithi ikhawulezisa ukuvela kwayo kubukrelekrele obukhulu, ukuqina okukhulu, kunye nobuhlobo nokusingqongileyo.

Siza kuqhubeka sihlola iinkalo ezinje ngoyilo lweefayibha ezikhethekileyo kunye nendlela yokwenza ngcono i-interfaces zekhonkrithi, ukukhuthaza ukuphuculwa kwemigangatho yoshishino kunye nophuhliso lwetekhnoloji, kunye nokubonelela ngezisombululo ezikhuphisanayo ngakumbi kwiiprojekthi zokwakha zanamhlanje.
