Mvura inoderedza mishonga inowanzoita anionic surfactants, uye ikozvino inowanzoshandiswa mumusika inosanganisira polycarboxylic acid based water reduction agents, naphthalene based water reduction agents, etc. Kunyange zvazvo vachichengetedza kudonha kwakafanana kwekongiri, vanogona kuderedza zvakanyanya kuwanda kwemvura inoshandiswa pakusanganiswa. , kunatsiridza simba rekrete, uye kuderedza kuitika kwekutsemuka. Vanoita basa rinokosha mukugadzirisa kushanda kwekongiri. Nekudaro, misanganiswa yekongiri yakasanganiswa nemvura inoderedza vamiririri inogona kusangana nematambudziko sekunamatira tangi uye manyepo kuseta. Kuti udzivise kuitika kwezvinetso zvakasiyana, Freeman anoongorora zvikonzero uye mhinduro dzematambudziko rimwe nerimwe.

一. Inogona kunamatira phenomenon:
Phenomenon: Chikamu chesamende inonamatira kumadziro emusanganiswa cylinder, zvichikonzera kusaenzana uye kushoma kuyerera kwemadota ekongiri, zvichikonzera kongiri inonamira.
Chikonzero chekuongorora:
Kongiri inonamira inowanzoitika mushure mekuwedzera maretarders uye mvura yekudzikisa maajenti, kana mumadhiramu musanganiswa ane akafanana axial dhayamita reshiyo.
Mitemo yekugadzirisa:
(1) Nenguva yakakodzera teerera kuchenesa uye kubvisa yasara kongiri;
(2) Chekutanga, wedzera aggregates uye imwe mvura kusanganisa, wobva wawedzera simende, yasara mvura, uye mvura inoderedza mumiririri kusanganisa;
(3) Shandisa yakakura shaft dhayamita reshiyo kana yekumanikidza musanganisi.

二.Pseudo coagulation phenomenon
Phenomenon: Kongiri mushure mekusiya muchina inokurumidza kurasikirwa nekuyerera kwayo uye haigone kudururwa.
Chikonzero chekuongorora:
(1) Kusakwana kwehuwandu hwe calcium sulfate uye gypsum mu simenti inotungamirira kukurumidza hydration ye calcium aluminate;
(2) Iyo yekudzikisa mvura inogadzirisa haina kuchinjika kune rudzi urwu rwesimende;
(3) Kana zviri mukati me triethanolamine zvinopfuura 0.05-0.1%, gadziriro yekutanga inokurumidza asi kwete yekupedzisira.
Mitemo yekugadzirisa:
(1) Chinja rudzi rwesimende;
(2) Kana zvichidikanwa, gadzirisa zvakasanganiswa uye ita zvine musoro kusanganisa;
(3) Wedzera Na2SO4 chikamu kune admixture.
(4) Deredza kupisa kwekusanganiswa
