Kuongororwa kwebasa rekongiri admixture:
Concrete Admixture chinhu chemakemikari chakawedzerwa panguva yekugadzirira kongiri yekugadzirira. Inogona kuchinja zvivakwa zvepanyama uye kushanda kwekushanda kwekongiri, nekudaro optimizing mashandiro ekongiri. Kutanga, kongiri admixture inotamba yakakosha basa mukuvandudza midziyo yekongiri. Kune rimwe divi, rinovandudza simba uye kusimba kwe kongiri. Nekuwedzera huwandu hwakakodzera hwezvibvumirano senge kusimbisa vamiririri uye kudzoreredza, simba rekumanikidza, simba rekusimbisa uye kusimba-thaw kuramba kongororo kunogona kuvandudzwa kunogona kuvandudzwa. Kune rimwe divi, zvinogona zvakare kuvandudza kumakemikari kurikitira kongiri. Semuenzaniso, kuwedzera zvinyoreso senge vamiririri vemvura uye vanochengetedza vanogona kuderedza kupinza zvinyoro-nyoro uye nemakemikari mukamuri uye kugadzirisa basa rekusimba uye kwebasa rekongiri. Kechipiri, kongiri admistures anotamba yakakosha basa mukudzora kushanda kwekushanda kwekongiri. Kuita kwekushanda kwekushanda kunoreva kupurasitiki, fluidity uye kufungisisa kongiri panguva yekuvaka. Nekuwedzera Admixture yakadai sekudonha kwemvura, tackfifiers uye mapurasitiki, iyo Fleidity uye kujekesa kongiri uye kuti ive nyore kushanda uye kuita kuti zvive nyore. Mukuwedzera, kuwedzera adminture yakadai seyemhepo foam vamiririri uye stibirizer inogona zvakare kudzora iyo bubble zvemukati uye kugadzikana kwekongiri kuti ienderane kune zvakasiyana enjinjini.
Tsvagurudzo pane chaiyo yekushandisa matanho eConcrete Admixture:
(1) kushandiswa kwemvura kuderedza mumiririri
Kubva pamaonero ekuita kwekuita kwemvura-kuderedza kwemvura, maitiro ayo anowedzera mvura ari pachena, uye ine zvirevo zvehunyanzvi. Kana iwe uchida kuve nechokwadi chekutsvedza kwekongiri, kana iwe uchikwanisa kuderedza mvura yekudzora mvura, iwe unogona kuderedza mari yemvura yakanyorwa yekuvandudza simba rechimiro chekongiri. Panguva imwecheteyo, kushandisa kunobudirira kwenzira iyi kunogona zvakare kuvandudza iyo density uye kusimba kwezvinhu zvepakango. Kana mvura yakawanda yemvura ichinge yashandiswa nekongiri. Nepo kuchengeta kusimba kwesimba rekongiri, kushandiswa kwemvura-kufungidzira kwemvura kunogona zvakare kuzadzisa chinangwa chekuvandudza chekudzora coment. Kuderedza zvisina kukodzera kuvaka mari yekudyara uye kuderedza mari yekubhadhara mari. Panguva yazvino, nzira dzakasiyana siyana dzemvura dzinoderedza vamiririri vakaoneka pamusika. Mhando dzakasiyana dzemvura-dzinodzora mvura ivhu zvine mutsauko wakanyanya kuve uri pachena maererano nesangano rekushandisa uye kushandisa mhedzisiro. Vashandi vanofanirwa kuvashandisa zvinokonzerwa nemamiriro ezvinhu chaiwo pane saiti.
(2) kushandiswa kwekutanga kusimbiswa mumiririri
Simba resimba rekutanga anonyanya kukodzera kuvaka nguva yechando kana emergency ekugadzirisa. Kana tembiricha yenzvimbo yekuvaka inowanikwa yakakwirira, kana tembiricha yave yakaderera kupfuura -5 ℃, iyi admiture haigone kushandiswa. Kune yakakura-vhorite kongiri kongiri, huwandu hwakawanda hwekupisa hydration huchaburitswa panguva yekushandisa, uye zvekutanga masimba masimba asina kukodzera kushandiswa. Panguva yazvino, iyo inoshandiswa zvakanyanya mashandisirwo emhando dzepamhepo dzinonyanya kufarirwa vamiririri vekutanga vamiririri uye chloride yekutanga vamiririri vekutanga. Pakati pavo, kubatsirwa kuri pachena kwazvo ndiyo munyu weClorine kutanga simba, iro rine sodium chloride, calcium chloride uye zvimwe zvinhu. Munguva yekushandiswa kweiyi yekutanga simba reMumiriri, Calcium chloride inogona kuita nemakemikari zvine chekuita nezvikamu zvine chekuita neSpessio mudenga, nokudaro kusimudzira kuumbwa kweiyo coment dombo chimiro. Mushure mekupedza izvo zviri pamusoro zvebasa zvemvura, zvinogona zvakare kuderedza dambudziko remvura yakawandisa mukodhi mune zvechinyakare, kuderedza zvakashata, uye kuzadzisa zvinangwa zvekuvandudza zvine simba zvakanyanya uye zvakakura density. Izvo zvinofanirwa kucherechedzwa kuti iyo chlorine munyu wekutanga mumiririri anogona kuve nemhedzisiro yekukosheswa pane iyo simbi chimiro panguva yekushandisa. Tichifunga nezve dambudziko iri, rudzi urwu rwechibvumirano haruna kukodzera kune yakakwaniriswa yakakwanirisa concrete yekuvaka mashandiro ekuvaka. Mukutsvagisa kune Sulfate yekutanga masimba masimba, sodium sulfate yekutanga mumiriri musimboti anoshandiswa zvakanyanya mumiriri weSimba reMumiriri. Kutonga kubva kune hunhu hwayo, hune simba remvura rakasimba. Uye kana ichisanganiswa muzvinyorwa zvekongiri, zvinogona zvakare kuitika kwemakemikari emakemikari nezvimwe zvinhu zviri musicement, pakupedzisira gadzira iyo inodiwa hydated calcium sulfaluminate. Mushure meizvi chinhu chinogadzirwa, chinogona kuwedzera kukurumidza kumhanya kwekumhanya kwesimendi. Chloride munyu wekutanga-masimba emumukuru uye sulfate yekutanga vamiririri vamiriri vekuAmerical munyu-wokutanga vamiririri vamiririri. Kana basa rinoenderana richida kuitwa pakutamba kwakakwirira, iyi yekutanga-simba mumiriri haigone kushandiswa. Mukushandiswa chaiko, vashandi vanofanirwa kusanganisa maitiro evakashata vamiririri vekutanga vamiririri uye mamiriro chaiwo pane saiti kuti asarudze zvakaringana zvekutanga mumiriri.
