1. Nyaya yekushandisa mvura
Muchigadziro chekugadzirira kongiri yepamusoro, kutarisisa kunofanira kubhadharwa pakusarudza yakanaka slag uye kuwedzera huwandu hwakawanda hwenhunzi madota. Iko kunaka kwemusanganiswa kuchakanganisa mvura inoderedza mumiriri, uye kune matambudziko nehutano hwekusanganiswa, izvo zvichange zvichikanganisa kushanda kwekrete. Kana kuchinjika kwe slag kwakanaka, chiyero che admixture hachifanirwe kunge chakakura, kana zvisina kudaro zvinogona kukonzera matambudziko ekubuda ropa. Izvo zvinodikanwa kudzora chikamu chenhunzi madota mukongiri kuti ive nechokwadi chekuti mvura inodzikisa mumiriri inoita basa riri nani.

2. Kusanganisa mari nyaya
Kugovaniswa kunonzwisisika kwenhunzi dota uye slag kunogona kuvandudza mashandiro ekongiri, kuderedza kushandiswa kwesimende mukuvaka engineering, uye kuderedza mari yezvinhu. Iko kunaka uye kunaka kwekusanganiswa kuchakanganisa kushanda kwemvura inoderedza mumiririri. Kuvandudza kushanda kwekongiri kunoda zvimwe zvinodikanwa zvekunaka uye kunaka kweiyo admixture. Mukugadzirisa kwekugadzirisa kongiri yepamusoro, kushandiswa kwehupfu hwe slag mumusanganiswa unogona kuvandudza kushanda kwayo. Huwandu hwekusanganiswa hunofanirwa kugadziridzwa zvine mutsindo zvichienderana neiyo chaiyo engineering mamiriro, uye dosi inofanira kudzorwa.

3. Mvura inoderedza agent dosage nyaya
Kushandiswa kwezvinoderedza mvura mukongiri yekutengeserana kunoda kunzwisiswa kwesainzi kwehuwandu hwemashandisi ekudzikisa mvura anoshandiswa uye kutonga zvine musoro kwezviyero zvavo. Sarudza marudzi akasiyana-siyana emvura inoderedza vashandi zvichienderana nerudzi rwesamende mukrete. Muzvirongwa zvekuvaka, dosage yemvura inoderedza vamiririri inoda kutariswa mushure mekuedzwa kwakawanda kuti uwane nyika yakanaka.

4.Aggregate nyaya
Iwo akaunganidzwa anoshandiswa mukongiri anofanirwa kuongororwa kubva kune akawanda maonero, aine makuru ekuongorora zviratidzo anosanganisira chimiro, particle grading, chimiro chepamusoro, madhaka emukati, kongiri yedhaka yemukati, uye zvinhu zvinokuvadza zvirimo. Izvi zviratidzo zvichave nekumwe kukanganisa pamhando yeaggregates, uye kutarisisa kwakanyanya kunofanirwa kubhadharwa kune iyo madhaka emukati. Izvo zviri mukati medhaka zvidhinha mukongiri hazvigone kudarika 3%, zvikasadaro kunyangwe kana vagadziri vemvura vawedzerwa, mhando yekongiri haigone kusangana neyakajairwa. Semuenzaniso, imwe purojekiti yekuvaka inoshandisa C30 cast-in-place pile kongiri. Munguva yekuedza kusanganisa nzira yekrete, apo mvura inoderedza mumiririri wechiyero i1%, inogona kusangana nezvinodiwa zveinjiniya, kusanganisira fluidity, slump kuwedzera, etc. Zvisinei, kuwedzera mvura inoderedza vamiririri maererano nekuedza data panguva yekuvaka haigoni kusangana. izvo zvinodikanwa zveinjiniya kana kuzadzisa zviyero zvakatarwa. Mushure mekuongorora nekuongorora kwenyanzvi, zvakagumiswa kuti chikonzero chikuru chechiitiko ichi ndechekuti madhaka emukati muchikamu chakanaka anodarika 6%, ayo anokanganisa kudzikisa mvura. Uye zvakare, akasiyana maumbirwo eakaomesesa aggregate particles anogona zvakare kukanganisa mvura yekudzikisa mhedzisiro yemvura inoderedza mumiririri. Iyo fluidity yekongiri inodzikira nekuwedzera kwezvinhu uye coarse aggregates. Mushure mekuongorora kwesainzi, hazvina kukwana kuvimba chete pamvura yekudzikisa maajenti kuti uvandudze mashandiro ekongiri uye kuwedzera simba rayo. Izvo zvinodiwa kukwirisa musanganiswa wekongiri kuitira kuti uwane mhedzisiro yakanaka.
