Ukusebenza okuphezulu kwe-superplasticizer emelwe yi-polycarboxylate superplasticizer inezibonelelo zomxholo ophantsi, izinga eliphezulu lokucutha amanzi, ukugcinwa kakuhle kokuthotywa kokusebenza kunye nokuncipha okuphantsi, kunye ne-polycarboxylate superplasticizer superplasticizer inomlinganiselo othile wokubangela, obangela ukuguquguquka, ukumelana neqabaka kunye nokugcinwa kwamanzi. yekhonkrithi engcono kuneyemveli yeplasticizer.Ngenxa yenkqubo eyahluka-hlukeneyo yokudityaniswa kwe-polycarboxylate superplasticizer, umgangatho wemveliso wabavelisi abohlukeneyo wahluke kakhulu, udityaniswa nenkqubo yokuvelisa, ngenxa yokuguquguquka komgangatho wemathiriyeli ekrwada yekhonkrithi, utshintsho lwesiqulatho samanzi esantini, impazamo inkqubo yokulinganisa kunye nezinye izizathu, okubangelwa umsebenzi ongazinzanga womxube wekhonkrithi (kulula ukwahlula okanye ukulahleka kwelahleko ngokukhawuleza) kwinkqubo yokwakhiwa kwe-polycarboxylate superplasticizer.Andikwazi nokuhlangabezana neemfuno zokwakha.Indlela yokukhetha i-polycarboxylate superplasticizer ekulula ukuyilawula kwaye kulula ukuyivelisa umgangatho ozinzileyo yenye yezinto ezibalulekileyo zokufezekisa umgangatho ozinzileyo wekhonkrithi.
Kukhetho lwepolycarboxylate superplasticizer ukongeza kuvavanyo olusisiseko lokusebenza, njengomxholo oqinileyo, inqanaba lokuncitshiswa kwamanzi, ukugcinwa kokudodobala kunye nolunye uvavanyo lokusebenza, ubuntununtunu bepolycarboxylate superplasticizer kufuneka buvavanywe ukuvavanya ngokubanzi umgangatho wepolycarboxylate superplasticizer.
(1) Ukufumanisa uvakalelo ekutshintsheni umthamo
Lungisa umlinganiselo womxube wovavanyo wekhonkrithi kwimeko yokuba ukusebenza kunye nokugcinwa kokudilika komxube wekhonkrithi kuhlangatyezwana neemfuno, gcina idosi yezinye izinto ezikrwada zekhonkrithi zingatshintshwanga, zandise okanye zinciphise isixa se-admixture nge-0.1% okanye i-0.2% ngokulandelelanayo, kwaye Khangela ukudilika kunye nokwandiswa kwekhonkrithi ngokulandelelanayo.Umncinci umehluko phakathi kwexabiso elilinganisiweyo kunye nomlinganiselo osisiseko wokudibanisa, ubuthathaka obungaphantsi kokutshintsha kwexabiso lokuxuba.Kuboniswa ukuba i-arhente yokunciphisa amanzi inovakalelo oluhle kwidosi.Injongo yolu phawu kukuthintela imeko yomxube wekhonkrithi ukusuka kutshintsho olukhawulezileyo ngenxa yempazamo yenkqubo yokulinganisa.
(2) Ukubona ubuntununtunu ekutshintsheni ukusetyenziswa kwamanzi
Ngokufanayo, ngokusekwe kumxube womxube womxube wekhonkrithi xa uhlangabezana neemfuno, isixa sezinye izinto eziluhlaza sihlala singatshintshi, kwaye ukusetyenziswa kwamanzi kwekhonkrithi kwandiswa okanye kunciphe nge-5-8kg / cubic meter ngokulandelanayo, oko kukuthi, ukuguquguquka umthamo wamanzi wesanti ulinganiswe nge-1%, kwaye ukudilika kunye nokwandiswa komxube wekhonkrithi kulinganiswa ngokulandelelanayo.Umncinci umehluko phakathi komxube wekhonkrithi kunye nomlinganiselo wokuxuba osisiseko, ngcono uvakalelo lokusetyenziswa kwamanzi okunciphisa amanzi.Ukuba utshintsho kusetyenziso lwamanzi alukhathali, kunokuba lula ukulawula imveliso.
(3) Vavanya ukulungelelaniswa kwemathiriyeli ekrwada
Gcina umlinganiselo wokuxuba osisiseko ungatshintshi, utshintshe izinto eziphathekayo eziphathekayo, ngokulandelelana ukuvavanya ukuchithwa kunye nokwandiswa kweenguqu zomxube wekhonkrithi emva kokutshintsha, kwaye uvavanye ubuninzi bokulungelelanisa kwizinto eziluhlaza.
(4) Ukuziqhelanisa nokutshintsha kobushushu
Gcina umlinganiselo womxube osisiseko ungatshintshi, ngokulandelelana uvavanye utshintsho lwe-slump kunye nokwandiswa komxube wekhonkrithi emva kokutshintsha, uvavanye ukulungelelaniswa kwendalo yonke kwizinto eziluhlaza.
(5) Guqula umlinganiselo wesanti
Yandisa okanye unciphise isantya sesanti nge-1%, jonga imeko yomxube wekhonkrithi, uvavanye ukuguquguquka kwesixa sesanti kunye negrabile, kunye nokuba imeko yekhonkrithi itshintshe kakhulu.
