Ekuqaleni, imixube yayisetyenziselwa ukugcina isamente kuphela. Ngophuhliso lobugcisa bokwakha, ukongeza i-admixtures ibe ngumlinganiselo omkhulu wokuphucula ukusebenza kwekhonkrithi.
I-concrete admixtures ibhekisela kwizinto ezongezelelweyo ukuphucula kunye nokulawula ukusebenza kwekhonkrithi. Ukusetyenziswa kwemixube ekhonkrithi kubunjineli ifumana ingqwalasela eyongeziweyo. Ukongezwa kwe-admixtures kudlala indima ethile ekuphuculeni ukusebenza kwekhonkrithi, kodwa ukhetho, iindlela zokongezwa, kunye nokulungelelaniswa kwe-admixtures kuya kuchaphazela kakhulu uphuhliso lwabo.
Ngenxa yobukho bezixhobo eziphezulu zokunciphisa amanzi, ikhonkrithi ephezulu yolwelo olumanzi, ikhonkrithi yokuzidibanisa, kunye nekhonkrithi eyomelele kakhulu; Ngenxa ye
ubukho bee-thickeners, ukusebenza kwekhonkrithi engaphantsi kwamanzi kuphuculwe. Ngenxa yobukho be-retarders, ixesha lokumisela isamente landisiwe, okwenza kube lula ukunciphisa ilahleko yokudilika kunye nokwandisa ixesha lokusebenza lokwakha. Ngenxa yobukho be-antifreeze, indawo yokukhenkceza yesisombululo iyancipha, okanye ukuguqulwa kwesakhiwo sekristale ye-ice akubangeli umonakalo weqhwa.
Iziphene kwikhonkrithi ngokwayo:
Ukusebenza kwekhonkrithi kumiselwa ngumlinganiselo wesamente, isanti, igrabile, namanzi. Ukuze kuphuculwe ukusebenza okuthile kwekhonkrithi, umlinganiselo wezinto ezikrwada unokulungiswa. Kodwa oku kudla ngokukhokelela kwilahleko kwelinye icala. Ngokomzekelo, ukwenzela ukwandisa umbane wekhonkrithi, umthamo wamanzi osetyenziswayo unokunyuswa, kodwa oku kuya kunciphisa amandla ekhonkrithi. Ukuze kuphuculwe amandla okuqala ekhonkrithi, isixa sesamente sinokunyuswa, kodwa ngaphezu kokunyuka kweendleko, kunokunyusa ukuncipha kunye nokunyuka kwekhonkrithi.
Indima yemixube yekhonkrithi:
Ukusetyenziswa kwe-concrete admixtures kunokuphepha iziphene ezikhankanywe ngasentla. Kwiimeko apho kukho impembelelo encinci kwezinye iipropati zekhonkrithi, ukusetyenziswa kwe-concrete admixtures kunokuphucula kakhulu uhlobo oluthile lwentsebenzo yekhonkrithi.
Ngokomzekelo, nje ukuba i-0.2% ukuya kwi-0.3% ye-calcium lignosulfonate i-agent yokunciphisa amanzi yongezwa kwikhonkrithi, ukuchithwa kwekhonkrithi kunokunyuswa ngokuphindwe kabini ngaphandle kokunyusa umthamo wamanzi; Okoko nje i-2% ukuya kwi-4% ye-sodium sulfate calcium sugar (NC) i-agent edibeneyo yongezwa kwikhonkrithi, inokuphucula amandla okuqala ekhonkrithi nge-60% ukuya kwi-70% ngaphandle kokunyusa umthamo wesamente, kwaye inokuphucula i-concrete. amandla kade kwekhonkrithi. Ukongeza i-anti crack compactor inokuphucula kakhulu ukuxhathisa kokuqhekeka, ukungagungqi, kunye nokuqina kwekhonkrithi, kuphuculwe ngokupheleleyo amandla exesha elide.
