Kana sment hydrate, inoumba chimiro chekutanga chinoputira mvura mukati. Kuti uite hydration yakawanda uye uvandudze kushanda kwekuvaka kwekongiri, imwe mvura inoda kuwedzerwa. Kuwedzera kweAdminture kunogona kuve kwekushambadzira pamusoro pechikamu chechikamu, kuti pamusoro pezvikamu zvechikamu, izvo zvinoparadzaniswa nemvura yakaputirwa muchimiro chekutanga, ichibvumira mvura yakawanda yekutora chikamu mu hydration yekuita uye kugadzirisa fluidity.

Nekudaro, nekuda kwezvikonzero zvakasiyana, admixture uye simende zvakare inowanzoenderana nematambudziko asingaenderane. Zviratidzo zvikuru ndezvekuti:

(1) Kugamuchirwa hakugadzirise zvakanyanya kuita basa rekushanda;

(2) kurasikirwa kwekutsvedza kwekongiri kwakakura kwazvo kana kongiri yemakonzo nekukurumidza;

.

Matambudziko aya achakanganisa zvakanyanya kunaka kwekongiri, aunza zvakavanzika kune kunaka kweprojekiti, uye kunyange kukonzeresa tsaona dzeinjiniya mumatambudziko akakura, zvichikonzera kurasikirwa kwakakosha kwehupfumi.

Kugadzirisa dambudziko rekusakwana pakati pezvibvumirano uye simende, kudzivirira ndiyo kiyi, uye kutarisirwa kunofanirwa kubhadharwa kune kusarudzwa kwezvinhu uye kuongororwa kwezvinhu zvinouya. Kuenderana kweAdminture uye simende inyaya yakaoma yakaoma. Kana paine dambudziko risingapindirani pakati peAdmixture uye simende, vagadziri vekongiri vanofanirwa kutora matsamba munguva. Sekureva kwemamiriro ezvinhu, zvichienderana nekuedzwa, ongorora uye uwane zvikonzero, gadzirisa iyo concrete ratio, wedzera fekitori slump, uye kuderedza kurasikirwa kwekutsvedza.

Kazhinji, huwandu hwekubhururuka ashge hunogona kugadziriswa, huwandu hwesmixture unogona kuwedzerwa, chikamu chemvura chinosara chesimumari mukukongana chinogona kuwanikwa, huwandu hwemvura hunogona kuchengetwa chisina kuchinjika, uye huwandu hwesimende inogona kuwedzera, Asi izvi pasina mubvunzo vanowedzera iyo unit mutengo. Iyo yechipiri yekuwedzera nzira inogona kushandiswawo panguva yekugadzira, ndiko kuti kutsvedza kunodzorwa pa80-100, uye iyo Solution Solution inokurudzirwa kwemaminitsi maviri usati washandisa pane iyo nzvimbo yekuvaka kuti igadzirise kusvika pa140. Uku kurapwa kwakawanda zvehupfumi uye zvinoshanda.

Vagadziri vekongiri vanowanzoda admixture kuti vajaire kuenderana neyekuwedzera, ndiko kuti, kuraira kwemvura kuyamwisa sekushandiswa kwesimbe kunoshandiswa nemugadziri wekongiri, kana wedzera Plasticze uye mhepo inopinda mumiririri neBubble kugadzikana, etc. Kana uchitsvaga iyo Concrete Unganidza Ratio panguva yekuvaka, nguva yekuisa yekongiri inoda kuenderana, uye kuyambira kunofanirwa kuve nechikamu chekudzosera. Kana iyo tembiricha yakangoerekana yadonha, yakawandisa inoshandiswa mukongiri, uye formula haina kugadziriswa munguva, kongiri haizogadzi kwenguva yakareba, iyo ichakanganisa zvakanyanya simba rekongiri. Muzhizha, kuvaka kunofanira kudzivisa kupisa kwakanyanya nemhepo ine simba masikati, uye zvigadzirwa zvakatsvuka zvinofanirwa kutonhorera. Iyo jecha ratio panguva yekuvaka inofanirwa kugadziriswa zvinoenderana nehukuru hwejecha rakajeka uye iko kupokana kweiyo coarse agregate.
