Iziphumo kumgangatho wesanti eyenziwe ngumatshini kunye nokulungelelaniswa kwe-admixture kumgangatho wekhonkrithi

Ilitye lomama kunye neteknoloji yokuvelisa isanti eyenziwe ngomatshini kwimimandla eyahlukeneyo ihluke kakhulu. Izinga lokufunxa amanzi kwisanti eyenziwe ngomatshini ichaphazela ilahleko yokudilika kwekhonkrithi ukuya kumlinganiselo othile, kwaye umxholo ogqithisileyo womgubo wodaka kwisanti eyenziwe ngumatshini awuyi kuchaphazela kuphela amandla ekhonkrithi, ngakumbi ukubuya okuqinileyo. Amandla e-Elastic kunye nokuqina, okubangela ukuba kwenzeke i-powdering ebusweni bekhonkrithi, kunye nokungathandekiyo kulawulo lweendleko zesityalo sokuxuba. Imodyuli ye-fineness yesanti eyenziweyo ngoku eveliswayo ngokusisiseko yi-3.5-3.8, okanye nokuba yi-4.0, kwaye uhlengahlengiso lwaphukile kakhulu kwaye alukho ngqiqweni. Umlinganiselo ophakathi kwe-1.18 kunye ne-0.03mm incinci kakhulu, nto leyo ingumngeni wokumpompa ikhonkrithi.

1. Ngethuba lokuveliswa kwesanti eyenziwe ngomatshini, umxholo we powder wamatye kufuneka ulawulwe ngokungqongqo ukuba ube malunga ne-6%, kwaye umxholo wodaka kufuneka ube ngaphakathi kwe-3%. Umxholo we-powder wamatye uyongezwa kakuhle kwisanti ephukile eyenziwe ngumatshini.

2. Xa ulungiselela ikhonkrithi, zama ukugcina umlinganiselo othile womgubo wamatye ukuze ufezekise i-gradation efanelekileyo, ngokukodwa ukulawula inani elingaphezulu kwe-2.36mm.

3. Kwisiseko sokuqinisekisa amandla ekhonkrithi, umlinganiselo wesanti kufuneka ulawulwe kakuhle, umlinganiselo wegrabile enkulu kunye encinci kufuneka ube nengqiqo, kwaye ubuninzi begrabile encinci inokunyuswa ngokufanelekileyo.

4. Isanti yomatshini wokuhlamba ngokusisiseko isebenzisa i-flocculant ukuze iqhube kwaye isuse udaka, kwaye inxalenye enkulu ye-flocculant iya kuhlala kwintlabathi egqityiweyo. I-flocculant ephezulu ye-molecular weight inefuthe elikhulu ngokukodwa kwi-arhente yokunciphisa amanzi, kwaye umbane kunye nelahleko ye-slump yekhonkrithi nazo zinkulu ngakumbi xa isixa sokuxutywa siphindwe kabini.

Impembelelo yeAdmixture kunye neAdmixture Adaptability kuMgangatho weConcrete

Uthuthu lwempukane yesityalo esinamandla sele lunqongophele, kwaye uthuthu lwempukane egayiweyo luyazalwa. Amashishini anesazela esilungileyo aya kongeza umlinganiselo othile wothuthu olukrwada. Amashishini anentliziyo emnyama onke angumgubo wamatye. Enkulu, umsebenzi ngokwesiseko yi-50% ukuya kuma-60%. Ubungakanani be-limestone powder exutywe kwi-fly ash ayiyi kuchaphazela kuphela ilahleko ekutshisweni kwe-fly ash kodwa ichaphazela umsebenzi wayo.

1. Yomeleza ukuhlolwa kokusila umlotha wempukane, ubambe utshintsho lwelahleko yayo ekutshiseni, kwaye ubeke ingqalelo kumlinganiselo wemfuno yamanzi.

2. Umlinganiselo othile we-clinker unokongezwa ngokufanelekileyo kwi-fly ash yokusila ukwandisa umsebenzi.

3. Akuvumelekanga ngokungqongqo ukusebenzisa i-coal gangue okanye i-shale kunye nezinye izinto ezinokufunxa kwamanzi aphezulu kakhulu ukugaya uthuthu lwempukane.

4. Inani elithile leemveliso ezinezithako zokunciphisa amanzi zinokongezwa ngokufanelekileyo kwi-fly ash ash, enempembelelo ethile ekulawuleni umlinganiselo wemfuno yamanzi.
