Kuongororwa kweConcrete Admixture:
1. Admentures yekuvandudza zvivakwa zvezvinyorwa zvekongiri, kusanganisira dzakasiyana siyana mvura inoderedza, mhepo-yekupindira vamiririri uye vamiririri vema.
2.
3. Admixtures yekuvandudza kujairwa kwekongiri, kusanganisira mhepo-yekupindira vamiririri, vamiririri vemvura uye ngura inthbitors, nezvimwe.

Water Romes:
Mvura kuderedza mumiririri kunoreva kushamwaridzana kunogona kuita kuti ushande kongiri isina kuchinjika uye zvakanyanya kuderedza kusanganisa kwayo kwemvura. Sezvo mvura yekudzora mumiririri inowedzerwa kune iyo imba yekusanganisa, kana iyo mvura yekudhara haina kuchinjwa, basa rayo rinogona kuve rakanyatsogadziriswa, saka mvura inoderedza mumiririri zvakare inonzi zvakare plasticze.
1. Maitiro ekuita kweiyo mvura yekudzora mumiririri mushure mekusanganiswa nemvura, nzvimbo yemasimende ichakwevera imwe neimwe uye inoumba akawanda marfa mumvura. MuFloc chimiro, mvura yakawanda yekusanganisa yakarukwa, zvekuti mvura iyi haigone kutamba basa rekuwedzera ruzha rwechisimba. Kana mumiririri wekuderedza mvura, iyo yekudzora kwemvura inogona kupaza zvinhu izvi zvidiki zvinowedzera uye kusunungura iyo yemvura yakasarudzika yemahara, nekudaro achinatsa fluidity yemusanganiswa wemusanganiswa. Panguva ino, kana kushanda kwekongiri yekutanga kuchiri kuchida kuchengetedzwa, mvura yekusanganisa inogona kuderedzwa zvakanyanya uye kudzora mvura kudzora mhedzisiro kunogona kuwanikwa, saka inonzi mvura yekuderedza mumiririri.
Kana simba rikaramba risina kuchinjika, huwandu hwesimbe inogona kuderedzwa apo ichidzora mvura kuti izadzise chinangwa chekuponesa simendi yekuchengetedza.
2. Izvo zvehunyanzvi uye zvehupfumi zvinokonzeresa kushandisa mvura kuderedza mumiririri ane inotevera technical uye hupfumi mhedzisiro
a. Iyo huwandu hwemvura yekusanganisa inogona kuderedzwa ne5 ~ 25% kana anopfuura kana iyo basa riripo isina kuchinjika uye huwandu hwesimende haina kuderedzwa. Sezvo ruzha rwemvura rwakaderedzwa nekudzora huwandu hwemvura yekusanganisa, simba rinogona kuwedzera ne15-20%, kunyanya simba rekutanga rinovandudzwa zvakanyanya.
b. Pasi pemamiriro ekuchengeta iyo yekutanga ratio ratio isina kuchinjika, kutsvedza kwemusanganiswa kunogona kuwedzera kwazvo (100 ~ 200mm kunogona kuwedzerwa), zvichiita kuti zvive nyore kuvaka uye kusangana nezvinodiwa zvekupomba kwevakakomberedza chivakwa.
c. Kana iyo Simba uye Kurovedza kuchengetedzwa, simende inogona kuponeswa ne 10 ~ 20%.
d. Nekuda kwekuderedzwa kwehuwandu hwekusanganisa mvura, kubuda ropa uye kusarudzika kwemusanganiswa kunogona kuvandudzwa, izvo zvinogona kuvandudza kuyamwisa kwechando uye kusakwana kwekongiri. Naizvozvo, kusimba kwekongiri inoshandiswa kuchave kwakagadziriswa.
3. Parizvino inowanzo shandiswa mvura inoderedza
Mvura kuderedza vamiririri vanonyanya kusanganisira Lignin Series, Naphthalene Series, Resin Series, molses Seriociency mvura yekudzora mumiririri, yekudzora mvura yekudzora mumiririri, kudzorera zvinoenderana ne basa guru. Mvura kuderedza mumiririri, mweya-yekupandukira mvura kudzora mumiririri, nezvimwe.
