Kushandiswa kwekongiri admixtures kunovandudza zvakanyanya kuyerera kwekongiri uye kunoderedza huwandu hwesimende zvinhu mukongiri. Naizvozvo, kongiri admixtures anoshandiswa zvakanyanya. Muchiito chekugadzira kwenguva refu, zvakaonekwa kuti nhepfenyuro zhinji dzekusanganisa dzine kusanzwisisana mukushandiswa kweanosanganisa, zvichikonzera kusakwana kwekongiri simba, kusashanda zvakanaka, kana yakawandisa kongiri musanganiswa mutengo.
Kuziva mashandisirwo akakodzera ezvisanganiswa zvinogona kuwedzera simba rekongiri uchichengeta musanganiswa mutengo usina kuchinjwa; kana kuderedza musanganiswa mutengo uchichengeta simba rekongiri; chengetedza chiyero chemvura-samende chisina kuchinjwa, kuvandudza kushanda kwekongiri.
A.Kusanzwisisana kwakajairika pamusoro pekushandisa admixtures
(1) Tenga admixtures nemitengo yakaderera
Nekuda kwemakwikwi anotyisa emusika, chiteshi chekusanganisa chine kutonga kwakasimba pakutenga kwezvinhu. Kusanganisa zviteshi zvese zvinotarisira kutenga zvigadzirwa nemutengo wakaderera, uye zvakafanana zvinoenda kune kongiri admixtures. Zviteshi zvekusanganisa zvinodzikisira mutengo wekutenga we admixtures, izvo zvinozotungamira kune vanogadzira admixture vadzikise mazinga avo emhando. Kazhinji, maitiro ekugamuchirwa emusanganiswa haawanzo kutsanangurwa muzvibvumirano zvekutenga zvekusanganisa zvirimwa. Kunyange kana iripo, inongoenderana nezvinodiwa nenyika, uye zvinodiwa nenyika kazhinji ndizvo zvakaderera. Izvi zvinotungamira kune chokwadi chekuti kana vanogadzira admixture vahwina bhidhiri nemutengo wakaderera, zvisanganiswa zvavanopa ndezvemhando yakaderera uye kazhinji haakwane zvinodikanwa zvepasirese, zvichiita kuti zviome kuzadzisa zvinodikanwa zvebasa rekusanganisa chiteshi chekushandisa. zvinosanganiswa.
(2) Deredza kuwanda kwezvinowedzera
Chiyero chekuita sarudzo chechiteshi chekusanganisa chinotarisisa mutengo wemusanganiswa, uye inotove nezvinodiwa zvakajeka pane simende dosi uye admixture dosage. Izvi zvinozoita kuti dhipatimendi rehunyanzvi risatya kupaza danho rekuita sarudzo's yakakwira dosage zvinodiwa zvekuwedzera kana uchigadzira musanganiswa reshiyo.
(3) Kushaikwa kwekutarisa kwemhando uye kuyedza kugadzirira kuongororwa kweadhimixtures
Parizvino, pakuongorora kwekuchengetera kwezvakasanganiswa, zviteshi zvekusanganisa zvakawanda zvinoitisa imwe kana mbiri yezviratidzo zvehunyanzvi zvakaita seyakasimba yemukati, mwero wekudzikisa mvura, density, uye fluidity yeakachena slurry. Zviteshi zvishoma zvekusanganisa zvinoitisa bvunzo dzekongiri.
Muchiito chekugadzira, takaona kuti kunyangwe iyo yakasimba yemukati, chiyero chekudzikisa mvura, density, fluidity uye zvimwe zviratidzo zvehunyanzvi zvemusanganiswa zvichisangana nezvinodiwa, bvunzo yekongiri inogona kuramba isisaite mhedzisiro yemusanganiswa wekuyedza, kureva, kongiri yekudzikisa mvura mwero haina kukwana. , kana kuti kusagona kuchinjika.
B. Mhedzisiro yekushandiswa zvisina kufanira kwezvisanganiswa pane kongiri yemhando uye mutengo
Nekuda kweiyo yakaderera yemhando yeadhimixtures inotengwa nemitengo yakaderera, kuitira kuti iwane yakakwana yekudzikisa mvura mhedzisiro, madhipatimendi ehunyanzvi anowanzo kuwedzera dosage yezvakasanganiswa, zvichikonzera yakaderera-mhando uye yakawanda-chinangwa admixtures. Zvakapesana, dzimwe nhepfenyuro dzakagadzikana dzemhando yekudzora uye zvirinani musanganiswa reshiyo mutengo wekudzora shandisa zvakasanganiswa zvemhando yepamusoro nemitengo yepamusoro. Nekuti yepamusoro-soro uye kushomeka kushandiswa, iyo unit mutengo we admixtures inoderera.
Zvimwe zviteshi zvekusanganisa zvinodzikamisa huwandu hwemisanganiswa. Kana kudonha kwekongiri kusingakwane, dhipatimendi rehunyanzvi rinogona kuderedza hunyoro hwejecha nematombo, kana kuwedzera kushandiswa kwemvura payuniti yekongiri, izvo zvinozotungamira mukuderera kwesimba rekongiri. Madhipatimendi ehunyanzvi ane pfungwa yakasimba yemhando achaita zvisina kunanga kana zvakananga kuwedzera unilateral mvura kushandiswa kwekongiri uye panguva imwechete zvakakodzera kuwedzera huwandu hwesimende zvinhu (kuchengeta mvura-simende ratio isingachinji), zvichikonzera kuwedzera kwemutengo we kongiri musanganiswa ratio.
Iyo yekusanganisa chiteshi inoshaya yekutarisisa kwemhando uye gadziriro yekuyedza yeadhimikisi. Kana iyo mhando yezvinowedzera ichichinja (inodzikira), iyo tekinoroji dhipatimendi ichiri kushandisa yekutanga musanganiswa ratio. Kuti usangane nekongiri yekudonha zvinodiwa, iyo chaiyo yemvura inoshandiswa yekongiri inowedzera, chiyero chemvura-samende chinowedzera, uye simba rekongiri rinoderera.
