Udaka sisixhobo sokwakha esibalulekileyo esisetyenziswa kwiiprojekthi ezinkulu nezincinane zokwakha.Idla ngokuba nesamente, isanti namanzi kunye nezinye izongezo.Nangona kunjalo, ngokuqhubela phambili kwethekhnoloji, izongezo ezininzi ziye zaziswa ukuphucula amandla okudibanisa, ukuguquguquka kunye nokuxhathisa kwamanzi omdaka.
Enye yeentshayelelo zamva nje kwihlabathi lezongezo zodaka kukusetyenziswa kweepolymers ezibophayo.Iipolima zeBinder zizinto ezenziweyo ezomeleza ukomelela kwebhondi yodaka.Zongezwa kumdaka ngexesha lokuxuba kwaye ziphendule ngesamente ukuze zenze ibhondi eqinile.Ukusetyenziswa kweepolymers ezibophelelayo kuye kwaboniswa ukuphucula iimpawu zomatshini zodaka, okwenza ukuba zixhathise ukuqhekeka kunye nokungena kwamanzi.
Esinye isongezo esiye sathandwa kwiminyaka yamuva nje i-polymer powder ehlanjululwayo (RDP).I-RDP yipolymer esetyenziselwa ukuphucula iimpawu zodaka.Yenziwe ngomxube we-polymer resins ezithi zixutywe kunye nomgubo wesamente, amanzi kunye nezinye izongezo.I-RDP iya ithandwa kakhulu ngenxa yokuguquguquka kwayo kunye neempawu ezizodwa.
Enye yeenzuzo eziphambili zokusebenzisa i-RDP ngodaka kukukwazi ukunyusa ukuguquguquka kwemveliso egqityiweyo.Olu phawu lubaluleke ngakumbi kwiindawo apho izakhiwo zithandwa ziinyikima nezinye iintlobo zeentlekele zemvelo.Iintsimbi ezenziwe nge-RDP zibonakaliswe ukuba zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala nazo.Ukongeza, iRDP inokomeleza ukunganyangeki kwamanzi, iyenze ibe sisongezo esiluncedo kwiindawo ezinemvula eninzi.
Ukongeza ekuphuculeni ukuguquguquka kunye nokunganyangeki kwamanzi, i-RDP ikwaphucula ukusebenza kodaka.Iqinisekisa ukuba udaka lusasazeka kwaye lusete ngokulinganayo, ukwenza ukwakhiwa kube lula kubakhi.Oku kuluncedo ngakumbi xa kusakhiwa iindonga, imigangatho, kunye neminye imiphezulu efuna ukugqibezela okufanayo.I-RDP iphinda inciphise umthamo wamanzi afunekayo ngexesha lokuxuba, okubangela udaka oludibeneyo kunye ne-voids embalwa.
Ukusetyenziswa kwezongezo zodaka ezifana neepolima ezibophelelayo kunye nomgubo wepolymer odispersible kwakhona uguqula ishishini lokwakha.Iifama eziqulethe ezi zongezo zomelele, ziguquguquka ngakumbi kwaye zixhathisa amanzi, ziqinisekisa isakhiwo esihlala sihlala kwaye sihlala ixesha elide.Kufuneka kuqatshelwe ukuba ezi zongezo kufuneka zisetyenziswe ngokwemilinganiselo efanelekileyo.Imilinganiselo ekhuthazwa ngumenzi kufuneka ilandelwe ukuphepha ukuchaphazela umgangatho wodaka.
Ishishini lokwakha lihlala liguquka kwaye uphuculo olwahlukeneyo lwezixhobo zokwakha lunika umdla.Ukusetyenziswa kwezongezo kwi-mortars, ezifana ne-polymers ezibophelelayo kunye ne-polymer powders redispersible, linyathelo elichanekileyo lokuqinisekisa isakhiwo esihlala sihlala kwaye sinamandla.Ezi zongezo ziqinisekisa ukuba isakhiwo sinokumelana neentlekele zemvelo, izikhukhula kunye nezinye izinto ezinokuphazamisa ingqibelelo yayo.Ke ngoko, le nkqubela phambili kufuneka yamkelwe kwaye isetyenziselwe ukwakha izakhiwo ezingcono nezomeleleyo kwixesha elizayo.
