Waya wachitsulo wokonzedwa kale ndi waya wachitsulo wapamwamba kwambiri wopangidwa ndi waya wopangidwa ndi chitsulo cha kaboni wambiri. Pambuyo potenthetsera ndi kukonza konkire wokonzedwa kale kuti akwaniritse zofunikira za konkire wokonzedwa kale. Kuchuluka kwa mpweya wa waya wachitsulo wamtunduwu ndi 0.65% mpaka 0.85%, ndipo sulfure ndi phosphorous zonse zili pansi pa 0.035%. Waya wachitsulo wokonzedwa kale wakhala akupangidwa m'mafakitale kuyambira m'ma 1920. Pambuyo pa zaka makumi ambiri akupangidwa, zinthu zingapo zoyenera kugwiritsidwa ntchito zosiyanasiyana zapangidwa.
Kuchokera pamalingaliro ofotokozera, mphamvu yokoka ya waya wachitsulo wolimbikitsidwa nthawi zambiri imakhala yoposa 1470MPa. Kwa zaka zambiri, mphamvu ya waya yasintha kuchoka pa 1470MPa ndi 1570MPa kufika pa 1670~1860MPa. M'mimba mwake wayayo inasinthanso, kuchoka pa 3 mpaka 5 mm kufika pa 5 mpaka 7 mm. Mafotokozedwe awa amatsimikizira kulimba ndi kugwira ntchito bwino kwa zipangizo zomwe zimalimbitsa nyumba za konkire.
Gulu limodzi la waya wokhazikika likuphatikizapo waya wokokedwa ndi ozizira, waya wowongoka ndi wofewa, waya wopepuka, waya wopepuka, ndi waya wopindika. Mitundu iyi imapereka mawonekedwe osiyanasiyana kuti ikwaniritse zosowa zosiyanasiyana. Mwachitsanzo, waya wachitsulo wopangidwa ndi ozizira umadziwika ndi malo ake osalala komanso mphamvu zake zokoka kwambiri. Waya wowongoka ndi wofewa umapereka kusinthasintha kwabwino komanso kugawa bwino kwa kupsinjika. Waya wopepuka umachepetsa kutayika kwa prestress. Waya wachitsulo wopindika umalimbana ndi dzimbiri, pomwe waya wachitsulo wopindika umathandizira kumamatira ku konkire.
Kapangidwe ka waya wachitsulo wokonzedwa kale kamapangitsa kuti azifunidwa kwambiri pantchito yomanga. Mphamvu yake yolimba kwambiri imatsimikizira kuti imatha kupirira katundu wolemera komanso kukana kusintha. Njira zopangira molondola zimatsimikizira kuti ndi zabwino komanso zodalirika. Ili ndi njira zosiyanasiyana zomwe zingagwiritsidwe ntchito kuti zigwirizane ndi zofunikira za polojekiti inayake. Waya wachitsulo wokonzedwa kale umagwiritsidwa ntchito kwambiri pa milatho, nyumba, njanji, ndi zomangamanga zamisewu. Kugwiritsa ntchito kwake kumathandiza kulimbitsa nyumba za konkriti, kuwonjezera mphamvu zawo komanso mphamvu zonyamula katundu.
Chifukwa cha kusinthasintha kwake komanso mawonekedwe ake abwino kwambiri, waya wachitsulo wopangidwa ndi prestress wakhala umodzi mwa mitundu ya chitsulo chopangidwa ndi prestress yomwe imagwiritsidwa ntchito kwambiri padziko lonse lapansi. Kwa zaka zambiri, kupanga kwake kwakhala kukuwonjezeka nthawi zonse kuti kukwaniritse zosowa zomwe makampani omanga akukulitsa. Mwa kukwaniritsa zofunikira zolimba zolimbitsa konkriti wopangidwa ndi prestress, waya wachitsulo uwu ukupitilizabe kugwira ntchito yofunika kwambiri pakuwonetsetsa kuti zomangamanga zosiyanasiyana padziko lonse lapansi ndi zotetezeka komanso zolimba.
Kugwiritsa ntchito
Monga makampani otsogola mumakampani opanga zinthu zachitsulo ku China, malonda achitsulo ndi zinthu zamtundu wa "Zana la bizinesi yabwino", makampani ogulitsa zitsulo ku China, "Mabizinesi 100 apamwamba kwambiri ku Shanghai". Shanghai Zhanzhi industry Group Co., Ltd., (yofupikitsidwa ku Zhanzhi Group) imatenga "Umphumphu, Kuchita Zinthu Mwanzeru, Kupanga Zinthu Mwatsopano, Kupambana" ngati mfundo yokhayo yogwirira ntchito, nthawi zonse imapitiliza kuyika zofuna za makasitomala pamalo oyamba.
