Ingxoxo ngezinto ezichaphazela ukunyibilika kwesinyithi

Ukutyibilika kwesamente, okubizwa ngokuba kukusebenza okanye ukuhambelana kwayo, luphawu olubalulekileyo oluchaphazela iinkalo ezahlukeneyo zokwakha, kubandakanya ukulula kokubekwa, ukuxinana, kunye nokugqitywa. Zininzi izinto ezichaphazela ukutyibilika kwesamente, kwaye ukuqonda ezi zinto kubalulekile ekufezekiseni ukusebenza kakuhle kwiiprojekthi zokwakha. Nantsi ingxoxo ngezinye zezinto eziphambili ezichaphazela ukutyibilika kwesamente:

1. Umlinganiselo wamanzi kwi-Binder: Umlinganiselo wamanzi kwi-binder, omele umlinganiselo wamanzi kwizinto ezisetyenziswa kwi-samente (isamente, ilayimu, okanye indibaniselwano), uchaphazela kakhulu ukunyibilika kwe-mortar. Ukwandisa umxholo wamanzi kunokuphucula ukusebenza ngokunciphisa ukuxinana kunye nokwandisa ukuhamba kwamanzi. Nangona kunjalo, amanzi amaninzi anokukhokelela ekuhlukaneni, ukopha, kunye nokuncipha kwamandla, ngoko ke kubalulekile ukugcina umlinganiselo ofanelekileyo wamanzi kwi-binder ukuze kubekho ukunyibilika okufunekayo ngaphandle kokuphazamisa ukusebenza kwe-mortar.
2. Uhlobo kunye noHlelo lweeAggregates: Uhlobo, ubungakanani, imilo, kunye noHlelo lweeAggregates ezisetyenziswa kwi-mortar zichaphazela iimpawu zayo ze-rheological kunye nokugeleza kwayo. Ii-aggregates ezintle, ezifana nesanti, ziphucula ukusebenza ngokugcwalisa izithuba kunye nokuthambisa amasuntswana, ngelixa ii-aggregates ezinkulu zibonelela ngozinzo kunye namandla. Ii-aggregates ezilinganisiweyo kakuhle kunye nokusasazwa ngokulinganayo kobukhulu beesuntswana zinokuphucula uxinano lokupakisha kunye nokuhamba kwamanzi kwi-mortar, okubangela ukugeleza kunye nokuhlangana okuphuculweyo.
3. Ukusasazwa kobungakanani beenxalenye: Ukusasazwa kobungakanani beenxalenye zezinto ezisimende kunye nee-aggregates kunefuthe kuxinano lokupakisha, ukungqubana phakathi kweenxalenye, kunye nokuhamba kakuhle kwe-mortar. Iinxalenye ezincinci zinokuzalisa izithuba phakathi kweenxalenye ezinkulu, zinciphise ukumelana nokungqubana kwaye ziphucule ukuhamba kakuhle. Ngokwahlukileyo koko, umahluko omkhulu kubungakanani beenxalenye unokukhokelela ekuhlukanisweni kweenxalenye, ukuxinana okungekho semgangathweni, kunye nokuncipha kokugeleza kwamanzi.
4. Umxube weekhemikhali: Umxube weekhemikhali, ofana nokunciphisa amanzi, iiplastiki, kunye nee-superplasticizer, unokuchaphazela kakhulu ukutyibilika komdaka ngokutshintsha iimpawu zawo ze-rheological. Umxube wamanzi unciphisa umxholo wamanzi ofunekayo ukuze kubekho ukuhla, nto leyo ephucula ukusebenza ngaphandle kokuphazamisa amandla. Iiplastiki ziphucula ubumbano kwaye zinciphisa ukuxinana, ngelixa ii-superplasticizer zibonelela ngokuhamba kwamanzi okuphezulu kunye neempawu zokuzilinganisa, ngakumbi kwii-mortar ezizixineneyo.
5. Uhlobo lweBinder kunye noBume bayo: Uhlobo kunye nokwakheka kwezinto ezidibanisa izinto, ezifana nesamente, ilayimu, okanye iindibaniselwano zazo, zichaphazela i-hydration kinetics, ixesha lokubeka, kunye nokuziphatha kwe-rheological kwesamente. Iintlobo ezahlukeneyo zesamente (umz., isamente yasePortland, isamente exutyiweyo) kunye nezinto ezongezelelweyo zesamente (umz., uthuthu oluphumayo, i-slag, i-silica fume) zinokuchaphazela ukugeleza kunye nokuhambelana kwesamente ngenxa yokwahluka kobukhulu bee-particle, reactivity, kunye neempawu ze-hydration.
6. Inkqubo Yokuxuba Nezixhobo: Inkqubo yokuxuba kunye nezixhobo ezisetyenziselwa ukulungiselela udaka zinokuchaphazela ukutyibilika kunye nokusebenza kwalo. Iindlela ezifanelekileyo zokuxuba, kubandakanya ixesha elifanelekileyo lokuxuba, isantya, kunye nolandelelwano lokudibanisa izinto, zibalulekile ekufezekiseni ukusasazeka okufanayo kwezithako kunye neempawu ezifanayo ze-rheological. Ukuxuba okungafanelekanga kunokukhokelela ekusweleni kwamanzi ngokwaneleyo, ukwahlulwahlulwa kwamasuntswana, kunye nokusasazwa okungalinganiyo kwe-additures, okuchaphazela ukutyibilika nokusebenza kodaka.
7. Iimeko Zendalo: Izinto ezinje ngobushushu, ukufuma, kunye nesantya somoya zinokuchaphazela ukutyibilika kwesamente ngexesha lokuxuba, ukuthuthwa, kunye nokubekwa kwayo. Amaqondo obushushu aphezulu akhawulezisa ukufuma kunye nokubekwa kwayo, anciphise ukusebenza kwaye andise umngcipheko wokuqhekeka kweplastiki. Amaqondo obushushu aphantsi anokuthintela ukubekwa kwayo kwaye anciphise ukutyibilika, afune ukulungiswa komlinganiselo wokuxuba kunye needosi zokuxuba ukuze kugcinwe ukusebenza okufunekayo.

Ukutyibilika kwesamente kuphenjelelwa yindibaniselwano yezinto ezinxulumene nezixhobo, uyilo lomxube, iinkqubo zokuxuba, kunye neemeko zokusingqongileyo. Ngokuqwalasela ngononophelo ezi zinto kunye nokwenza ngcono umlinganiselo womxube, iingcali zokwakha zinokufikelela kwisamente ngokutyibilika okufunekayo, ukuhambelana, kunye nokusebenza kwizicelo ezithile kunye neemfuno zeprojekthi.
