Indlela yokumisela ukuhambelana kodaka olumanzi oluxutywe ngodaka?
Udaka lwemasonry oluxutywe manzi sisixhobo esiyimfuneko esisetyenziswa ekwakheni ukuze kudityaniswe iiyunithi zobumeki njengezitena, iibhloko, namatye. Ukungaguquguquki kodaka lwemasonry oluxutyiweyo luyipropathi ebalulekileyo echaphazela ukusebenza kwayo, ukusebenza, kunye nokuqina. Ukumisela ukuhambelana kodaka olumanzi oluxubeneyo lwe-masonry kubalulekile ukuqinisekisa ukuba luyahlangabezana neenkcukacha ezifunekayo kunye nemigangatho. Kweli nqaku, siza kuxubusha iindlela zokumisela ukuhambelana kodaka olumanzi oluxutywe ngamanzi.
Ukubaluleka kokungaguquguquki
Ukuhambelana kweudaka lwamatye olumanzi oluxubeneyongumlinganiselo weplastiki yayo, ukusebenza kwayo, kunye nomxholo wamanzi. Kubalulekile ukumisela ukuhambelana kodaka oluxutyiweyo olumanzi ukuze kuqinisekiswe ukuba lunokufakwa lula, lusasazeke, kwaye lusetyenzwe kumalungu phakathi kweeyunithi zemasonry. Udaka olome kakhulu luya kuba nzima ukulusebenzisa kwaye lunokubangela ukunamathela okungahambi kakuhle phakathi kweeyunithi ze-masonry. Udaka olumanzi kakhulu luya kuba nzima ukuphatha kwaye lunokubangela ukushwabana okugqithisileyo, ukuqhekeka, kunye nokunciphisa amandla.
Iindlela zokumisela ukungaguquguquki
Kukho iindlela ezininzi zokumisela ukuhambelana kodaka oluxutywe nomanzi, kubandakanya:
- Flow Table Test
Uvavanyo lwetafile yokuqukuqela yindlela esetyenziswa ngokubanzi yokumisela ukuhambelana kodaka olumanzi oluxutyiweyo lwemasonry. Uvavanyo lubandakanya ukubeka isampuli yodaka kwitafile yokuhamba kunye nokulinganisa ububanzi bayo bokusasazeka emva kwenani elichaziweyo lamaconsi. Itheyibhile yokuqukuqela iqulathe ipleyiti ethe tyaba esetyhula efakwe ngokuthe tye kwi-shaft ethe nkqo. I-plate ijikelezwe ngama-degrees angama-90 kwaye iyancipha ukusuka ekuphakameni kwe-10 mm kwisiseko esisisigxina. Udaka lubekwe embindini wepleyiti kwaye luvunyelwe ukuba luhambe. Ububanzi bokusabalalisa bulinganiswa emva kokuhla kwe-15, kwaye uvavanyo luphinda luphindwe kathathu, kwaye ixabiso eliqhelekileyo libalwe.
- Uvavanyo lokuNgena kweKhowuni
Uvavanyo lokungena kwekhowuni yenye indlela esetyenziswayo ukufumanisa ukuhambelana kodaka olumanzi oluxubeneyo lwemasonry. Uvavanyo lubandakanya ukulinganisa ubunzulu apho i-cone esemgangathweni ingena khona isampuli yodaka phantsi komthwalo ochaziweyo. I-cone esetyenziswe kuvavanyo inobubanzi obuyi-35 mm, ubude be-90 mm, kunye nobunzima be-150 grams. I-cone ibekwe phezu kwesampuli yodaka kwaye ivunyelwe ukuba ingene imizuzwana emihlanu phantsi komthwalo we-500 grams. Ubunzulu bokungena bulinganiswa, kwaye uvavanyo luphinda luphindwe kathathu, kwaye ixabiso eliphakathi libalwa.
- Vee-Bee Consistometer Test
Uvavanyo lwe-Vee-Bee Consistometer yindlela esetyenziselwa ukufumanisa ukusebenza kunye nokuhambelana kodaka oluxutywe nomanzi. Uvavanyo lubandakanya ukuzalisa isitya se-cylindrical ngodaka kunye nokulinganisa ixesha elithathiweyo kwintonga yentsimbi esemgangathweni ukuze ingcangcazele ngamaxesha angama-150 ngesampuli. I-Vee-Bee Consistometer iqukethe itafile eshukumayo, isitya se-cylindrical, kunye nentonga yensimbi. Intonga yensimbi inobubanzi be-10 mm kunye nobude be-400 mm. Isikhongozeli sigcwaliswa ngodaka kwaye sibekwe phezu kwetafile engcangcazelayo. Intonga yensimbi ifakwe kumbindi wesampuli, kwaye itafile isethelwe ukungcangcazela kwi-frequency ye-60 Hz. Ixesha elithathiweyo ukuze intonga igqibe ukungcangcazela kwe-150 ilinganiswa, kwaye uvavanyo luphinda luphindwe kathathu, kwaye ixabiso eliphakathi libalwa.
Imiba echaphazela ukungaguquguquki
Izinto ezininzi zinokuchaphazela ukuhambelana kodaka oluxutyiweyo olumanzi, kubandakanya:
- Umxholo wamanzi: Ubungakanani bamanzi ongeziweyo kumxube wodaka unokuchaphazela kakhulu ukuhambelana kwawo. Amanzi amaninzi anokubangela umxube omanzi kunye ne-runny, ngelixa amanzi amancinci angabangela umxube oqinileyo nowomileyo.
- Ixesha lokuxuba: Ubungakanani bexesha lokuxutywa kodaka kunokuchaphazela ukuhambelana kwayo. Ukuxuba kakhulu udaka kunokubangela ukuba ube manzi kakhulu, ngelixa ukuxutywa ngaphantsi kunokukhokelela kumxube owomileyo noqinile.
- Ubushushu: Ubushushu bomxube wodaka bunokuchaphazela ukuhambelana kwawo. Amaqondo obushushu aphezulu anokubangela ukuba umxube ube lulwelo oluninzi, ngelixa amaqondo obushushu asezantsi anokubangela ukuba uqine.
- Uhlobo kunye noMyinge we-Aggregate: Uhlobo kunye nesixa se-aggregate esetyenziswe kwi-mortar inokuchaphazela ukuhambelana kwayo. Ii-aggregates ezicolekileyo zinokukhokelela kumxube omanzi ngakumbi, ngelixa ii-aggregates ezinkulu zinokukhokelela kumxube oqinileyo.
- Uhlobo kunye nenani lezongezo: Uhlobo kunye nobungakanani bezongezo ezisetyenziselwa udaka, njengeplastiki okanye i-air-entraining agents, nazo zinokuchaphazela ukuhambelana kwayo.
