Kurongeka kwekongiri admixtures:
1. Admixtures yekuvandudza rheological properties yekongiri yakasanganiswa, kusanganisira zvakasiyana-siyana zvinoderedza mvura, mhepo-entraining agents uye pumping agents.
2. Admixtures yekugadzirisa nguva yekugadzirisa uye kuomesa zvinhu zvekrete, kusanganisira retarders, vamiririri vekutanga-simba uye accelerators.
3. Admixtures yekuvandudza kusimba kwekrete, kusanganisira air-entraining agents, kudzivirira mvura uye rust inhibitors, nezvimwewo.
4. Admixtures yekuvandudza zvimwe zvinhu zvekrete, kusanganisira air-entraining agents, kuwedzera, antifreeze agents, colorants, kudzivirira mvura uye kupomba, nezvimwewo.
Mvura inoderedza:
Mvura inoderedza mumiririri inoreva musanganiswa unogona kuchengetedza kushanda kwekongiri kusachinjika uye kuderedza zvakanyanya kusanganisa kwayo kushandiswa kwemvura.Sezvo mvura inoderedza mumiriri inowedzerwa kuimba yekuvhenganisa, kana iyo unit mvura inoshandiswa isina kuchinjwa, kushanda kwayo kunogona kuvandudzwa zvakanyanya, saka iyo inoderedza mvura inonziwo plasticizer.
1. Nzira yekushanda kwemvura inoderedza agent Mushure mokunge simenti yakasanganiswa nemvura, zvimedu zvesimenti zvichakwezvana uye zvinogadzira flocs dzakawanda mumvura.Muchigadziro chefloc, mvura yakawanda yekuvhenganisa yakaputirwa, kuitira kuti mvura iyi irege kuita basa rekuwedzera mvura ye slurry.Kana iyo inoderedza mvura inowedzerwa, iyo inoderedza mvura inogona kuparadzanisa zvivako izvi zvinoputika uye kusunungura iyo yakavharidzirwa yemvura yakasununguka, zvichiita kuti iwedzere mvura yemusanganiswa.Panguva ino, kana kushanda kwekongiri yepakutanga kuchiri kuda kuchengetedzwa kusina kuchinjwa, mvura inosanganiswa inogona kuderedzwa zvakanyanya uye mvura inoderedza simba inogona kuwanikwa, saka inonzi mvura inoderedza mumiririri.
Kana simba rikaramba risina kuchinjwa, huwandu hwesimende hunogona kuderedzwa paunenge uchideredza mvura kuti uwane chinangwa chekuchengetedza simenti.
2. Izvo zvehunyanzvi uye zvehupfumi zvinokonzerwa nekushandisa mvura yekudzikisa mumiririri zvine zvinotevera zvehunyanzvi uye zvehupfumi mhedzisiro
a.Kuwanda kwekusanganiswa kwemvura kunogona kuderedzwa ne5 ~ 25% kana kupfuura apo kushanda kwekushanda kunoramba kusingashanduki uye kuwanda kwesamende hakuna kuderedzwa.Sezvo chiyero chemvura-samende chinoderedzwa nekuderedza kuwanda kwekusanganiswa kwemvura, simba rinogona kuwedzerwa ne15-20%, kunyanya simba rekutanga rinovandudzwa zvakanyanya.
b.Pasi pemamiriro ekuchengetedza musanganiswa wepakutanga wehuwandu husina kuchinjwa, kudonha kwemusanganiswa kunogona kuwedzerwa zvakanyanya (100 ~ 200mm inogona kuwedzerwa), zvichiita kuti zvive nyore pakuvaka uye kusangana nezvinodiwa zvekupomba kongiri kuvaka.
c.Kana simba uye kushanda zvakachengetwa, simenti inogona kuponeswa ne10 ~ 20%.
d.Pamusana pekuderedzwa kwehuwandu hwekusanganiswa kwemvura, kubuda ropa uye kupatsanurwa kwemusanganiswa kunogona kuvandudzwa, izvo zvinogona kuvandudza kupikisa kwechando uye kusagadzikana kwekrete.Nokudaro, kusimba kwekongiri inoshandiswa kuchavandudzwa.
3. Parizvino zvinowanzoshandiswa kuderedza mvura
Zvinoderedza mvura zvinonyanya zvinosanganisira lignin series, naphthalene series, resin series, molasses series uye humic series, nezvimwewo. Rudzi rwega rwega runogona kukamurwa kuva chigadziriso chekudzikisa mvura, chepamusoro-soro chekudzikisa mvura, simba rekutanga rekudzikisa mvura, retarder maererano ne basa guru.Mvura inoderedza mumiriri, mhepo-inopinza mvura inodzikisa mumiriri, nezvimwe.
