1. Isiphumo sokuguqulwa kwesamente sichaphazeleka yi-admixtures

Umbono wangaphambili we-double-layer unokuchaza kakuhle umphumo weplastiki wokongeza izinciphisi zamanzi kwikhonkrithi. Kwezo zikhonkrithi ezixutywe kunye nezongezelelo ezahlukeneyo zekhonkrithi, nangona isixa sesamente esisetyenzisiweyo sincitshisiwe ukuya kumlinganiselo othile, isixa somnciphisi wamanzi esongeziweyo siphindwe kabini kunesamente eqhelekileyo. Le nxalenye yophando kufuneka itsale ingqalelo yabasebenzi abafanelekileyo. Ukongeza, kwezinye iikhonkrithi ezinokuqina okuphezulu, amandla kunye namandla okutshintsha kwekhonkrithi elungiselelwe ngee-superplasticizers ezahlukeneyo zahluke kakhulu. Isizathu salo mcimbi kufuneka sisondelelene ngokusondeleyo nomphumo we-surfactants kwi-cement hydration. Ikhonkrithi ehamba phambili ene-samente yamanzi exutywe kunye ne-plasticizers iya kubonisa into ethi "ipleyiti" emva kwemizuzu elishumi emva kokuxuba, oko kukuthi, emva kokuwa kwekhonkrithi, ngokukhawuleza kuya kubonisa isiganeko sokumisa ubuxoki ukuba ayishukunyiswa, kwaye ikhonkrithi ephantsi inzima. Nangona kunjalo, le nto ayibonakali kwimixube yekhonkrithi eqhelekileyo ngaphandle kweeplastiki. Indlela yokuphepha kunye nokucacisa le ngxaki kufanelekile ukuxoxa.

2. Ukulungelelaniswa kwesamente kuchatshazelwa yi-admixtures

Kweyona nkqubo yokwakha, ingxaki enjalo ihlala isenzeka, oko kukuthi, phantsi komlinganiselo ofanayo wokuxuba, idosi ye-admixture kunye neemeko zokwakha, uhlobo kunye nebhetshi yesamente okanye i-admixtures utshintsho, okubangela ukuba kubekho umahluko omkhulu kwi-fluidity kunye ne-slump yekhonkrithi emiselweyo. Esona sizathu siphambili sale nto kukuba izinto ezifana nokwakheka kweeminerali zesamente, igypsum eneconditioned kunye nokucolwa kwesamente kukhokelela ekumisweni ngokukhawuleza ngexesha lokuxuba ikhonkrithi. Ke ngoko, uphononongo olupheleleyo lwengxaki yokuguquguquka kwesamente kulungelelaniso olufanelekileyo lwendlela yokusetyenziswa kunye nedosi ye-admixtures.

3. Impembelelo yendawo yokusetyenziswa kwimpembelelo ye-admixtures

Kwezo zikhonkrithi ezineplastiki ezihlukeneyo, xa ubushushu bendalo bufanelekile, ukudilika kunye nelahleko ye-slump yekhonkrithi ingcono kakhulu kunezo zifunyenwe phantsi kobushushu obuphezulu kunye neemeko ezomileyo, kodwa ukuba ebusika, ikhonkrithi ayinayo umehluko omkhulu, oya kuchaphazela inkqubo yokwakha ukuya kumlinganiselo othile.
