Kuwedzera kugamuchirwa kwematekinoroji matsva uye zviwanikwa kwave imwe yemisika mikuru yezvigadzirwa zvekuvaka mumakore apfuura.Makambani makuru epasirese ezvekuvaka akatanga kupa zvinhu zvitsva uye hunyanzvi hwekugadzira modular mabhuroko ekuvaka kumaindasitiri ekuvaka pasirese.Zvimwe zvezvivakwa zvetekinoroji zvemhando yepamusoro zvakaita sekongiri yakasimba, kongiri inoshanda, mineral admixtures, condensed silica fume, high-volume fly ash kongiri zviri kuwedzera kufarirwa.Zvishandiso zvitsva izvi zvinotarisirwa kuwedzera mashandiro ezvigadzirwa uye kushanda nesimba, nekudaro kufambisa kukura kweindasitiri yezvivakwa zvekuvaka munguva pfupi iri kutevera.
Kuvaka chinhu chipi nechipi chinoshandiswa pakuvaka senge zvinhu zvekuvaka imba.Huni, simende, aggregates, simbi, zvidhinha, kongiri, ivhu ndiyo yakajairika mhando yezvinhu zvekuvaka zvinoshandiswa pakuvaka.Kusarudzwa kweizvi kunobva pakubudirira kwavo kwemari yezvirongwa zvekuvaka.Zvinhu zvakawanda zvinongoitika zvoga, zvakaita sevhu, jecha, huni nematombo, kunyange matavi nemashizha zvakashandiswa kuvaka zvivakwa.Kunze kwezvinhu zvinongoitika zvoga, zvinhu zvakawanda zvakagadzirwa nevanhu zviri kushandiswa, zvimwe zvakawanda uye zvimwe zvishoma.Kugadzirwa kwezvinhu zvekuvakisa iindasitiri yakadzikwa munyika dzakawanda uye kushandiswa kwezvinhu izvi kunowanzo kupatsanurwa mune chaiwo hunyanzvi hunyanzvi, sekuveza, pombi dzemvura, denga uye basa rekudzivirira.Chirevo ichi chinobata nezvekugara nezvivakwa zvinosanganisira dzimba.
Metal inoshandiswa sechimiro chechimiro chezvivakwa zvakakura senge skyscrapers, kana sechifukidziro chekunze.Kune mhando dzakawanda dzesimbi dzinoshandiswa pakuvaka.Simbi isimbi alloy ine chikamu chikuru isimbi, uye ndiyo yakajairika sarudzo yesimbi structural kuvaka.Iyo yakasimba, inochinjika, uye kana yakanatswa zvakanaka uye/kana kurapwa inotora nguva yakareba.
Corrosion ndiye muvengi mukuru wesimbi kana zvasvika pakurarama kwenguva refu.Iyo yakaderera density uye nani corrosion kuramba kwealuminium alloys nemarata dzimwe nguva zvinokunda mutengo wavo mukuru.Brass yainyanya kuwanda munguva yakapfuura, asi kazhinji inongogumira kune chaiwo mashandisirwo kana zvakakosha zvinhu nhasi.Metal manhamba akanyanya mukurumbira muzvimiro zvakafanogadzirwa seQuonset hut, uye inogona kuoneka ichishandiswa mumaguta mazhinji ane cosmopolitan.Zvinoda basa guru revanhu kugadzira simbi, kunyanya muhuwandu hunodiwa kumaindasitiri ekuvaka.
Dzimwe simbi dzinoshandiswa dzinosanganisira titanium, chrome, goridhe, sirivheri.Titanium inogona kushandiswa pakuvaka, asi inodhura zvakanyanya kupfuura simbi.Chrome, goridhe, uye sirivheri zvinoshandiswa sekushongedza, nekuti zvinhu izvi zvinodhura uye hazvina hunhu hwekuita senge kusimba kwesimba kana kuoma.
