Ukurhweba kunye nophuculo olusebenzayo lwekhonkrithi lukhuthaza ukukhula kwe-admixtures
Ngokwahlukileyo kwigophe leMfuno elizinzile kushishino lwesamente, imixube inamandla athile okukhula, kunye nentsingiselo yokwandisa imfuno esezantsi yomlambo kunye nokusetyenziswa kweyunithi.I-Admixtures isetyenziswa kakhulu kwi-concrete edibeneyo edibeneyo, kwaye ukunyuka kwexabiso lokuthengisa kwekhonkrithi kubangele ukunyuka okuqhubekayo kwimfuno epheleleyo ye-admixtures.Ukusukela ngo-2014, imveliso yesamente izinzile, kodwa ukuveliswa kwekhonkrithi yorhwebo iye yanda unyaka nonyaka, ngesantya sokukhula sonyaka se-12% kule minyaka mihlanu idlulileyo.Ukuxhamla ekukhuthazeni umgaqo-nkqubo, ngakumbi nangakumbi iimeko zemfuno ezibambekayo zamkela ikhonkrithi esele ixutyiwe.Imveliso esembindini yekhonkrithi yorhwebo kunye nothutho kwisiza seprojekthi kusetyenziswa iilori zomxube ziluncedo ekufezekiseni ulawulo lomgangatho oluchanekileyo, ukulingana kwemathiriyeli yenzululwazi, ulwakhiwo olulula ngakumbi lokugalela, kunye nokunciphisa ngempumelelo ungcoliseko lokusingqongileyo olubangelwa yisamente eninzi kwiiprojekthi zokwakha.
Uphuculo lwemveliso kwizizukulwana lubonelela ngamandla okukhula okumandla kwiindidi zemveliso entsha
Ii-arhente zokunciphisa amanzi ngokwazo zinesakhono esinamandla sokukhula, ingakumbi ngenxa yamathuba abanzi okutshintsha okuziswe luphuculo lwesizukulwana esitsha.I-arhente yokunciphisa amanzi kwisizukulwana sesithathu, ekwabizwa ngokuba yiarhente yokunciphisa amanzi asebenza kakhulu, enepolycarboxylic acid njengeyona nto iphambili, ithe chu yaba yeyona nto iphambili kwintengiso.Izinga layo lokunciphisa amanzi linokufikelela ngaphezulu kwe-25%, kwaye inkululeko yayo yemolekyuli inkulu, inedigri ephezulu yokwenza ngokwezifiso kunye nokuhamba okugqwesileyo okukhuthaza ukusebenza.Oku kuphucula kakhulu ukwenzeka korhwebo lwekhonkrithi yamandla aphezulu kunye ne-ultra-high, kwaye ngoko ke umlinganiselo uyanda unyaka nonyaka.
Imodeli yoshishino lweshishini elongezelelweyo: ukwenza ngokwezifiso kunye ne-viscosity ephezulu
Abathengi ekujoliswe kubo kwii-arhente zokunciphisa amanzi ngabavelisi bekhonkrithi.Kukho ubukhulu becala iindidi ezimbini zamaqela, omnye ngumenzi wekhonkrithi wezorhwebo, indawo yakhe yoshishino izinzileyo, ikakhulu isasaza indawo eyi-50km ejikeleze isikhululo sokuxuba.Olu hlobo loncedo lwemveliso yabathengi luhlala lubekwe kufutshane nommandla wasezidolophini, ubukhulu becala lunceda izindlu, izakhiwo zoluntu zasezidolophini, ubunjineli bakamasipala kunye nezinye iiprojekthi.Okwesibini ngabaxumi bobunjineli, abafana neekontraka zokwakha kwiziseko zothutho ezinkulu kunye
ulondolozo lwamanzi kunye neeprojekthi zombane wamanzi.Ngenxa yokutenxa kwiiprojekthi zeziseko ezingundoqo kwiindawo zasezidolophini kunye nemfuno esasazekileyo, iinkampani zokwakha zihlala zizakhela ngokwazo izityalo zokuxutywa kwekhonkrithi endaweni yokusebenzisa ababoneleli bekhonkrithi abakhoyo esixekweni.
