1. Xa umxholo we-samente ufana kwaye i-slump ifana nekhonkrithi engenanto, ukusetyenziswa kwamanzi kungancitshiswa ngo-10-15%, amandla eentsuku ezingama-28 anganyuswa ngo-10-20%, kunye nonyaka omnye. amandla anokunyuswa malunga ne-10%.
2. Ukugcinwa kwesamente Xa amandla kunye nokudilika kwesamente kufana, malunga ne-10% yesamente inokugcinwa, kwaye iitoni ezingama-30-40 zesamente zingagcinwa ngokusebenzisa i-1 toni ye-arhente yokunciphisa amanzi.
3. Ukuphucula ukusebenza kwekhonkrithi Xa umxholo wesamente kunye nokusetyenziswa kwamanzi kwekhonkrithi kuhlala kungatshintshi, ukuchithwa kwekhonkrithi yeplastiki ephantsi kunokunyuswa malunga namaxesha amabini (ukusuka kwi-3-5 cm ukuya kwi-8-18 cm), kwaye amandla okuqala ngokusisiseko ikufutshane naleyo yekhonkrithi engaxutywanga.
4. Emva kokongeza i-0.25% ye-lignocelcium superplasticizer ene-retarding effect, xa i-concrete yekhonkrithi ifana ngokusisiseko, ixesha lokuqala lokumisela i-samente eqhelekileyo lilibazisekile kwiiyure ezingama-1-2, i-samente ye-slag yi-2-4 iiyure, ixesha lokugqibela lokumisela. yesamente eqhelekileyo iiyure 2, kunye nesamente slag iiyure 2-3.Ukuba i-slump inyuswa ngaphandle kokunciphisa ukusetyenziswa kwamanzi, okanye i-slump efanayo igcinwa ukugcina ukusetyenziswa kwe-cement, ukulibaziseka kwexesha lokumisela kukhulu kunokunciphisa amanzi.
5. Inokunciphisa ixesha lokwenzeka kwencopho ye-exothermic yobushushu bokuqala be-hydration yesamente, malunga neeyure ezi-3 zesamente eqhelekileyo, malunga neeyure ezi-8 ze-slag sement, kunye neeyure ezingaphezu kwe-11 ze-samente yedama.Elona qondo lobushushu liphezulu lencochoyi ye-exothermic lisezantsi kancinci kwisamente eqhelekileyo, kwaye lingaphantsi kwe-3 ℃ kwi-slag yesamente kunye nesamente yedama.
6. Umxholo womoya wekhonkrithi uyanda.Umxholo womoya wekhonkrithi engenanto malunga ne-1%, kwaye umxholo womoya wekhonkrithi oxutywe ne-0.25% ye-calcium yemithi malunga ne-2.3%.
7. Ukunciphisa izinga lokopha Ngaphantsi kwemeko yokuba ukudilika kwekhonkrithi ngokusisiseko kuyafana, izinga lokopha.calcium lignosulphonateingancitshiswa ngaphezu kwe-30% xa kuthelekiswa naleyo yekhonkrithi ngaphandlecalcium lignosulphonate.Ngaphantsi kwemeko yokuba umlinganiselo wamanzi-samente uhlala ungatshintshi kwaye ukunyuka kwanda, izinga lokuphuma kwegazi liyancipha ngenxa yepropathi ye-hydrophilic.calcium lignosulphonatekunye nokuqaliswa komoya.
8. Xa kuthelekiswa nalawo angenayo i-arhente yokunciphisa amanzi, ukusebenza kwe-shrinkage eyomileyo ngokusisiseko kusondele okanye kunciphe kancinci kwinqanaba lokuqala (1-7) iintsuku, kwaye kwanda kancinci kwinqanaba elilandelayo (ngaphandle kwezo zonga isamente), kodwa ixabiso lokunyuka alikho ngaphezu kwe-0.01% (0.01mm / m).
9. Ukuphucula ukubumbana kunye nokunganyanzeki kwekhonkrithi.Ukusuka ku-B=6 ukuya ku-B=12-30.
10. Ayinayo ityuwa yeklorini kwaye ayinayo ingozi yokubola ukuqinisa.
