Ukusombulula ingxaki yokungahambelani phakathi kwe-admixtures kunye ne-samente, kugxininiswe ekuthinteleni, ukukhethwa kwezinto eziphathekayo kunye nokufumanisa izinto ezingenayo.Ukulungelelaniswa kwe-admixtures kunye ne-samente yingxaki enzima, kwaye ingxaki yokungahambelani phakathi kwe-admixtures kunye ne-samente iyenzeka.Abavelisi bekhonkrithi bathatha amanyathelo afanelekileyo: ngokwemeko, ngokusekelwe kwiimvavanyo, uhlalutye kwaye ufumane izizathu, ulungelelanise umlinganiselo womxube wekhonkrithi, kwaye uphucule i-factory.i-slump, ukunciphisa i-slump loss.Kuhlala kuyimfuneko ukulungelelanisa inani le-fly ash, ukwandisa inani le-admixtures, ukwandisa intsalela yesigaba solwelo se-admixture kwikhonkrithi, ugcine i-samente yamanzi.
ratio ingatshintshwanga, nokwandisa isixa sesamente, nto leyo ngokungathandabuzekiyo kwandisa iyunithi iindleko.Okanye indlela yokongeza yesibini ingamkelwa, oko kukuthi, i-slump kwi-factory ilawulwa kwi-80-100, kwaye isisombululo se-admixture sishukunyiswa ngamandla malunga nemizuzu emi-2 ukulungelelanisa kwi-140 ngaphambi kokusetyenziswa kwindawo yokwakha, eyonga kakhulu. kwaye iyasebenza.Abavelisi bekhonkrithi bahlala befuna izongezelelo zokulungelelanisa kwisamente ngenxa yoluhlu olukhulu lwesamente, oko kukuthi, abavelisi be-admixture kufuneka balungelelanise i-formula, ngokutsho kwesamente esetyenziswa ngabavelisi bekhonkrithi ukulungelelanisa iintlobo kunye nezixa zokunciphisa amanzi kunye ne-retarders. kwii-additives, okanye ukwandisa inani lePlasticizer, i-air-entraining agent engenazo iibhubhu, njl.
Ukumiselwa komlinganiselo wokuxutywa kwekhonkrithi kwakhona kufuneka kuthathelwe ingqalelo ixesha lokudityaniswa kwekhonkrithi, i-admixture iqulethe izithako ezibuyisela umva, iqondo lobushushu lehla ngequbuliso kwiqondo lobushushu eliphezulu, umxube kwikhonkrithi ininzi kakhulu, kwaye ifomula ayilungiswanga. ekuhambeni kwexesha, okubangela ukungaphumeleli kwexesha elide lekhonkrithi.I-condensation iya kuchaphazela kakhulu amandla ekhonkrithi.Ehlotyeni, ukwakhiwa kufuneka kwakhona kuphephe ixesha lasemini lobushushu obuphezulu kunye nomoya, kunye nokupholisa izinto eziluhlaza.Ukumiselwa komlinganiselo wesanti kwi-concrete yokuxuba umxube wokwakha kufuneka kwakhona ulungelelaniswe ngokobukhulu be-santi fineness kunye ne-porosity ye-coarse aggregate.Ngoko, ingxaki yokungahambelani phakathi kwe-samente kunye ne-admixture ingasombululwa kwinqanaba elithile. kwaye ilahleko inokuncitshiswa.
