Umbhobho wentsimbi wesamente ochasene nomhlwa ubhekiselele kunyango oluxhathisayo lodaka lwesamente kumbhobho wentsimbi ngaphakathi kumzimba wetyhubhu.Ifakwe ngesamente udaka lwesamente umbhobho yentsimbi anti-umbhobho, umbhobho yentsimbi ezaliswe ngekhonkrithi, enokufunxa ubushushu obuninzi, kwaye ngenxa yoko wabandezeleka umtya icandelo lomlilo unikezelo lobushushu intsimi ayilingani kakhulu, ixesha lokumelana umlilo iintsika, ukucotha. izinga lokufudumala kweentsika zetsimbi, kwaye emva kokuba iintsika zetsimbi zivelise ikhonkrithi zingakwazi ukumelana nomthwalo omkhulu we-axial ukukhusela ukuwa kwesakhiwo.Ukuchasana nomlilo we-composite beam kuya kwanda, kuba ukushisa okuphantsi kweentsimbi zetsimbi kuya kuhambisa ubushushu ukusuka kwi-flange ephezulu ukuya kwikhonkrithi.
I-Cement mortar lining yodonga lombhobho kunye nokuhlukaniswa kwamanzi okanye igesi, ukubunjwa komgangatho okhuselekileyo wokukhusela ukuthintela i-oxidation kunye ne-corrosion yodonga lombhobho kwi-fouling yebhotile.Xa kuthelekiswa nolunye udaka oluchasene ne-corrosion, i-cement mortar kunye namandla adibeneyo odonga lombhobho, ngenxa yokuba i-hydration yeengqungquthela ze-samente zenza i-gel, udonga lwangaphakathi lombhobho wensimbi owenziwe ngamandla;ukucutheka komthamo we-cement mortar induration kufutshane nombhobho wentsimbi Umbutho, ukuvelisa ukukhuhlana;intsebenziswano eluma ngoomatshini phakathi kombhobho wentsimbi yangaphakathi ngodonga olungalinganiyo, ngodaka lwesamente.
Udaka lwesamente ngaphakathi kwenkqubo yokusebenza kombhobho wokutshabalalisa:
Umxube wesamente, isanti namanzi kuthiwa ngudaka lwesamente.1:3 udaka lwesamente luqhele ukubhekiswa ngokudibene nenxalenye enye yesamente kunye neenxalenye ezi-3 zesanti, ngokungakhathalelwanga ukubunjwa kwamanzi, ngokubanzi kumlinganiselo omalunga ne-0.6, ekufuneka ibe yi-0.6:1:3 ngeenjongo zodaka lwesamente Ubunjineli bokwakha, Okokuqala, isiseko kunye nodonga lokwakha, olusetyenziswa njengesibophelelo semathiriyeli yolwakhiwo olukhulu, olufana nengqushu yepuzzle, isitena esibomvu sokusebenzisa udaka lwesamente;yokutyabeka ngaphakathi nangaphandle.Udaka lwesamente xa lusetyenziswa, kodwa luhlala ludityaniswa nezinye izongezo, ezifana ne-micro-foaming agents, umgubo wamanzi ukuphucula ukusebenza kwawo kunye ne-viscosity.Ukongeza umlinganiselo wegrabile, udaka lwesamente ukuze lube ngekhonkrithi.
