1. Kana simenti yemukati yakafanana uye kudonha kwakafanana nekongiri isina chinhu, kushandiswa kwemvura kunogona kuderedzwa ne10-15%, simba remazuva makumi maviri nemasere rinogona kuwedzerwa ne10-20%, uye gore rimwe chete. simba rinogona kuwedzerwa neinenge 10%.
2. Kuchengetedza simende Kana simba uye kudonha kwekongiri kwakafanana, inenge 10% yesamende inogona kuchengetedzwa, uye matani 30-40 esimende anogona kuchengetedzwa nekushandisa tani imwe yemvura inoderedza mvura.
3. Kuvandudza kushanda kwekongiri Kana iyo simenti yemukati uye kushandiswa kwemvura kwekongiri kunoramba kusingachinji, kudonha kwekongiri yepurasitiki yakaderera kunogona kuwedzerwa kanenge kaviri (kubva pa3-5 cm kusvika 8-18 cm), uye simba rekutanga ndiro. zvakanyanya padyo neiyo yekongiri isina kusanganiswa.
4. Mushure mekuwedzera 0.25% lignocelcium superplasticizer ine retarding effect, apo kudonha kwekrete kunenge kwakafanana, nguva yekutanga yekuisa simende inononoka kwemaawa 1-2, simenti ye slag ndeye 2-4 maawa, nguva yekupedzisira yekuisa. Yesimende yakajairika maawa maviri, uye simenti ye slag ndeye 2-3 maawa. Kana iyo slump ichiwedzerwa pasina kuderedza kushandiswa kwemvura, kana kunyura kwakafanana kunochengetedzwa kuchengetedza simenti kushandiswa, kunonoka nguva yekuisa yakakura kudarika yekuderedza mvura.
5. Inogona kuderedza nguva yekuitika kwe exothermic peak yekutanga hydration kupisa kwesimende, iyo inenge maawa matatu kune yakajairika simende, anenge maawa masere e slag simende, uye anopfuura maawa gumi nerimwe edhamu simende. Iyo tembiricha yepamusoro ye exothermic peak yakadzikira zvishoma kune yakajairika simende, uye isingasviki 3 ℃ ye slag simende uye dhamu simende.
6. Mhepo yekongiri inowedzerwa. Mhepo yekongiri isina chinhu inenge 1%, uye mhepo yekongiri yakasanganiswa ne 0.25% yemiti calcium inenge 2.3%.
7. Kuderedzwa kwehuwandu hwekubuda ropa Pasi pemamiriro ekuti kudonha kwekongiri kwakangofanana, chiyero chekubuda ropa.calcium lignosulphonateinogona kuderedzwa neinopfuura 30% kana ichienzaniswa neyekongiri isinacalcium lignosulphonate. Pasi pemamiriro ekuti mvura-simende reshiyo inoramba isingachinji uye kudonha kunowedzera, chiyero chekubuda ropa chinoderera zvakare nekuda kweiyo hydrophilic pfuma.calcium lignosulphonateuye kuiswa kwemhepo.
8. Kuenzaniswa neavo vasina mumiriri wekudzikisa mvura, iyo yakaoma shrinkage kuita iri pedyo kana kuderera zvishoma padanho rekutanga (1-7) mazuva, uye yakawedzera zvishoma pane imwe nguva (kunze kweiyo inochengetedza simende), asi iyo kuwedzera kukosha hakusi kupfuura 0.01% (0.01mm/m).
9. Kuvandudza compactness uye kusapindira kwekongiri. Kubva B=6 kusvika B=12-30.
10. Haina chlorine munyu uye haina corrosion ngozi yekusimbisa.
