Ekhonkrithi
Ikhonkrithi (idla ngokufinyezwa iicl.) sisixhobo sokwakha, i-artificial conglomerate eyenziwe ngumxube we -binder, amanzi kunye ne -aggregates ecolekileyo nerhabaxa (isanti kunye negrabile) kunye nodibaniso, njengoko kuyimfuneko, lwezongezo kunye/okanye iiminerali ezongeziweyo. ziphembelela iimpawu zomzimba okanye zekhemikhali, kunye nokusebenza, kokubini [1] kunye nokuqina kwe-conglomerate.
Ngenkulungwane yamashumi amabini ananye isibophelelo esasisetyenziselwa ukwenza ikhonkrithi yisamente, kodwa kwixesha elidlulileyo iikonkrithi zazisenziwa ezazisebenzisa izibophelelo ezahlukeneyo ezifana ne -aerial okanye i-hydraulic lime. I-Gypsum ayifane isetyenziswe ukwenza ikhonkrithi "engalunganga".
Ikhonkrithi entsha iphonswa ngaphakathi kwifomwork kwaye idityaniswe kunye ne -vibrators, kodwa kukho iifomyula zanamhlanje zekhonkrithi ezibizwa ngokuba yi "self-compacting" (SCC), ezisisiseko kulwakhiwo lwangoku njengoko ziqinisekisa umgangatho olinganayo kunye nofanayo, awufuni ukungcangcazela. kwaye zihlanganiswe ngamandla omxhuzulane. I -samente, i-hydrating ngamanzi, isethi kwaye iyaqina, inika umxube ukuxhathisa okomatshini okufana nokufana nelitye .Isetyenziswa namhlanje ukwenza iindawo zesakhiwo kwaye yeyona nto isetyenziswa kakhulu emhlabeni.
