Kubva ma1980, vanonyanya kufarirwa, vanonyanya kubudiranira mvura kuderedza vamiririri, vakanyatso kusimudzwa uye vakanyatsoiswa mumusika wemba, kunyanya mune yakakwirira-ine simba kongiri, uye vava zvinhu zvisina musoro. Mashandisiro akaiswa Malhot Kwaingova nemhando shoma dzakakosha muKongana Congmasi Kwemakore, imwe yeiyo yaive yekuvandudzwa kwemhepo yakapihwa kuma1940, iyo yakashandura tekinoroji yekongiri kuNorth America;SuperplasticasizerImwezve breakthrough ichave nekukanganisa kukuru pakugadzirwa uye kushandiswa kwekongiri kwemakore mazhinji anouya.

SuperplasticasizerMune dzimwe nyika dzakadanwaSuperplasticasizer, sezita rinoratidza, rakakodzera kwazvo kugadzirira kweakanyanya concrete musanganiswa. Ehezve, zvakakodzera kwazvo kusanganisa kusanganisa nekuyerera kukuru, yakakura slumry vhoriyamu uye yakadzika mvura-binder chiyero, kureva kuti, kupomba yakakwirira-simba rakakwirira.

Nekudaro, kune imwe kongiri, yakadai sekongiri yakadururwa muHydraulic Kuvaka kuvakwa, saizi yezasi yakakura Nekushandisa kusimba kusimba kana kushungurudzika kunofamba-famba chiito, iyo yakakwira yekubudirira mvura kuderedza inogona kunge isina kukodzera. Kuti uchengete mvura-binder chiyero chisina kuchinjika, kuitira kuti ushandise ma parmeteral midziyo, kuderedza mvura yemvura, uye kuderedza mamiriro ekumusoro somedhiro mvura inobhadhara. Muchokwadi, chiitiko chakadai chinetso, nekuti zvakapfuura hydraulic kongiri inosanganiswa nemhepo yekushambadzira mumhepo yekudzora mvura, uye nekuda kwemhedzisiro yemhepo yekupindira, wedzera huwandu hwekupindira, saka Kana mvura yemvura uye huwandu hwezvinyorwa zvekusimanikidza zvakaderedzwa panguva imwe chete, kureva kuti, kana huwandu hweshuwa hwakaderedzwa, inogona kuchengetedza chiyero chakaoma. Kufunga kuti pane nzvimbo yakakwana yekuzadza iyo Aggregate, kuputira iyo Aggregate uye inopa iyo inoshanda slurry inodiwa kuti musanganiswa wacho abatiswe mushure mekudurura.

Uye zvakare, simba rekumanikidza remusanganiswa nekukwira kwemvura nekudzora mumvura kuti udzikise huwandu hwemvura hunogona kuvandudzwa kwazvo mushure mekushomeka, Kuvaka kweConcrete Paveement kana Bridge Panel inofanirwa kunge ichichenjerera neyakanyanya kugona kudzora mvura kuderedza mumiririri. Muchokwadi, mukugadzirira kwehuwandu hukuru hweC30 mukuvakwa kwehurumende uye kukohwa kweanopfuura 1/2 yehuwandu hwenzvimbo dzekongiri, yakakwira mvura yekudzvanya mari haifaniri kukodzera, kana hachisi chinhu chakakosha.
