Ukungena kuMoya: Ukufezekisa uMgangatho weConcrete oLungileyo

Ukunyanzeliswa komoya ngumba obalulekileyo wokufumana umgangatho wekonkrithi ongowona uphezulu, ngakumbi kwiimeko ezirhabaxa zokusingqongileyo okanye kwizicelo apho ukuqina kokunyibilika komkhenkce kubalulekile. Ikhonkrithi efakwe emoyeni iqulethe amaqamza amancinci asasazwe kulo lonke umxube, ophucula ukuxhathisa kwawo kwimijikelo yokunyibilika komkhenkce, iphucula ukusebenza, kwaye icuthe ukungena kwamanzi. Nantsi indlela ukungena komoya okunegalelo ngayo kumgangatho ogqibeleleyo wekhonkrithi kunye neendlela ezisetyenziselwa ukuyifeza:

Iinzuzo zokuNgena emoyeni:

1. I-Freeze-Thaw Ukuqina: Ukunyanzeliswa komoya kwandisa ukomelela kwekhonkrithi kwimijikelo yokunyibilika komkhenkce ngokunika indawo yokuba amanzi ande xa engumkhenkce. Oku kunciphisa amathuba okuqhekeka, ukuqhekeka, kunye nokuwohloka okubangelwa ngumonakalo owenziwe ngumkhenkce, ngakumbi kwiindawo ezibandayo.
2. Ukusebenza okusebenzayo: Ubukho bamaqamza omoya buphucula ukusebenza kwekhonkrithi ngokusebenza njengezinto zokuthambisa, ukunciphisa ukungqubana kwangaphakathi, nokuququzelela ukubekwa lula nokugqiba. Oku kuluncedo ngokukodwa kwikhonkrithi efuna ukumponthwa okanye ibekwe kwiindawo ezixineneyo zokuqinisa.
3. Ukuqina: Ukungena komoya kwandisa ukuqina kwekhonkrithi ngokunciphisa ukunyanzeliswa kwamanzi kunye nezinto ezinobundlobongela, ezifana ne-chlorides kunye ne-sulfates, ngaloo ndlela kunciphisa umngcipheko wokubola kunye nokuhlaselwa kweekhemikhali kwintsimbi yokuqinisa.
4. Uphuhliso lwamandla: Xa kulawulwa ngokufanelekileyo, ukungena komoya akuchaphazeli kakhulu amandla oxinzelelo lwekhonkrithi. Enyanisweni, inokwandisa amandla kunye nokuqina kwekhonkrithi kwixesha elide ngokuyikhusela kumonakalo kunye nokuwohloka.

Iindlela zokuPhumelela ukuNgena emoyeni:

1. I-Chemical Admixtures: I-Air-entraining admixtures, efana ne-synthetic surfactants okanye i-resin zomthi wendalo, zongezwa kumxube wekhonkrithi ngexesha lokuxuba. Ezi zidibaniso zizinzisa amaqamza omoya ngaphakathi kwekhonkrithi kwaye zilawule ubungakanani kunye nokuhanjiswa kwazo.
2. Ukuphazamiseka koomatshini: Iindlela zoomatshini, ezifana nokuxubana ngesantya esiphezulu okanye ukuphazamisa, zingasetyenziselwa ukufaka umoya kumxube wekhonkrithi. Oku kudla ngokuphunyezwa kusetyenziswa izixhobo ezikhethekileyo, ezinje nge-air-entraining admixture dispensers okanye imixube yokubheqa.
3. Uyilo oluLungileyo lweMixube: Ukukhethwa kwezinto ezifanelekileyo kunye nemilinganiselo kuyilo lomxube wekhonkrithi kubalulekile ekufezekiseni ukunyanzeliswa komoya. Izinto ezifana nohlobo lwesamente, ukuhlelwa kwe-aggregate, umlinganiselo wamanzi-samente, kunye ne-admixture dosage kufuneka ziqwalaselwe ngononophelo ukuqinisekisa umxholo womoya ofanayo kunye nokusabalalisa.
4. Uvavanyo kunye noLawulo loMgangatho: Uvavanyo oluqhelekileyo kunye namanyathelo okulawula umgangatho kuyimfuneko ukubeka iliso nokugcina umxholo womoya ofunwayo kunye nokuhambelana kumxube wekhonkrithi. Umxholo womoya ulinganisa ngokuqhelekileyo usebenzisa iimitha zoxinzelelo okanye iindlela ze-volumetric, kwaye uhlengahlengiso lwenziwa njengoko lufunekayo ukufezekisa iimfuno ezichaziweyo.

Isiphelo:

Ukunyanzeliswa komoya kudlala indima ebalulekileyo ekuphunyezweni kowona mgangatho uphezulu wekhonkrithi, ngakumbi kwizicelo apho ukuqina kunye nokumelana nemijikelo yokunyibilika komkhenkce kubaluleke kakhulu. Ngokubandakanya amaqamza omoya kumxube wekhonkrithi ngokusebenzisa imixube yeekhemikhali, ukuphazamiseka koomatshini, kunye noyilo lomxube olufanelekileyo, iinjineli kunye neekontraka zinokunyusa ukusebenza, ukuqina, kunye nokusebenza kwexesha elide kwezakhiwo zekhonkrithi kwiimeko ezahlukeneyo zokusingqongileyo. Ukuvavanya rhoqo kunye namanyathelo okulawula umgangatho kubalulekile ukuqinisekisa umxholo womoya ohambelanayo kunye nomgangatho kwimveliso yekhonkrithi.
