Malinga ndi akatswiri, chitsulo chakhala chinthu chofunikira kwambiri pa ntchito zomanga kwa zaka zambiri, zomwe zimapatsa mphamvu komanso kulimba. Komabe, pamene mitengo yachitsulo ikupitirira kukwera komanso nkhawa yokhudza mpweya woipa wa carbon ikukwera, pakufunika njira zina zothetsera mavuto.
Basalt rebarndi njira ina yabwino kwambiri yomwe ingathetse mavuto onse awiri. Chifukwa cha makhalidwe ake abwino komanso kusamala chilengedwe, imatha kutchedwa njira ina yabwino m'malo mwa chitsulo chachikhalidwe. Yochokera ku miyala yamoto, zitsulo za basalt zimakhala ndi mphamvu yokoka yodabwitsa, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana zomangira.
Basalt rebar ndi njira ina yodziwika bwino m'malo mwa chitsulo chachikhalidwe kapena fiberglass yolimbitsa konkire ndipo ikupita patsogolo ngati ukadaulo watsopano ku UK. Kugwiritsa ntchito njira yatsopanoyi pamapulojekiti otchuka monga High Speed ​​​​2 (HS2) ndi msewu waukulu wa M42 kukukulirakulira m'mapulojekiti omanga pamene ntchito yochotsa mpweya woipa ikupita patsogolo.
- Njira yopangira imaphatikizapo kusonkhanitsabasalt ya phiri la volcano, kuiphwanya m'zidutswa tating'onoting'ono ndikuisunga kutentha mpaka 1400°C. Ma silicate omwe ali mu basalt amawasandutsa madzi omwe amatha kutambasulidwa ndi mphamvu yokoka kudzera m'mapepala apadera, ndikupanga mizere yayitali yomwe imatha kufika mamita masauzande ambiri. Kenako ulusiwu umakulungidwa pa spools ndikukonzedwa kuti ukhale wolimba.
Pultrusion imagwiritsidwa ntchito kusintha waya wa basalt kukhala ndodo zachitsulo. Njirayi imaphatikizapo kutulutsa ulusi ndikuuviika mu utomoni wa epoxy wamadzimadzi. Utomoni, womwe ndi polima, umatenthedwa kukhala wamadzimadzi kenako ulusiwo umamizidwamo. Kapangidwe konse kamalimba mwachangu, n’kusanduka ndodo yomalizidwa mumphindi zochepa chabe.
