Admixtures ni wai-vakalailaitaka na cakacaka cecere: Vakatorocaketaka na cakacaka ni simede me baleta na tara ni Green
Vanua ni Kerekere Levu
Na veivakatorocaketaki ni wai-vakalailaitaka na veivakatorocaketaki cecere (me vaka na veivakatorocaketaki ni polycarboxylate-yavutaki) e matataka na mataqali veivakatorocaketaki duadua ni veivakatorocaketaki ni wai-vakalailaitaki e tiko ena makete. Era cakacaka ena kena buli e dua na itutu ni veivakasavasavataki ena dela ni simede, tarova na kena vakasoqoni vata na simede ka vakavinakataka kina na flowability kei na cakacaka ni simede. Na veivakasavasavataki oqo e sega walega ni vakalailaitaka na vakayagataki ni wai ia e vakalevutaka talega na density kei na kaukauwa ni simede. Ni vakatauvatani kei na admixtures ni wai-vakalailaitaka na itovo vakavanua, na vakadewa cecere-vakayagataki e solia na iwiliwili cecere ni vakalailaitaki ni wai (vakatautauvatataki 25%-40%) kei na lailai ni gagadre ni kaukauwa (dau 0.1%-0.3% ni levu taucoko ni iyaya simede), kei na dua na lailai ni veivakacacani ni vanua e tiko kina.
Ena cakacaka ni tara vale, na vakayagataki ni wai-vakalailaitaka na admixtures e rawa ni vakalevutaka sara vakalevu na kaukauwa ni compressive kei na wai ni simede, vakabalavutaka na bula ni veiqaravi ni veivakatorocaketaki. Me kena ivakaraitaki, ena kena tara na veivale cecere kei na idrodro lelevu, na admixtures cecere-vakalailaitaka na wai e vakadeitaka na flowability vinaka ni simede ena ruku ni gagadre cecere-kaukauwa, vakarawarawataka na cakacaka ni taravale. Me kena ikuri, na wai-vakalailaitaka na admixtures e rawa ni vakalailaitaka na dra kei na veiwasei ena simede, vakavinakataka na kena duavata kei na kena tudei.
Ena vanua ni tara vale drokadroka, na itovo ni vanua ni wai-vakalailaitaka na admixtures e bibi sara. Na vakayagataki ni admixtures cecere-vakalailaitaka na wai e rawa ni vakalailaitaka na vakayagataki ni simede, ka vakalailaitaka kina na kaboni. Kuria, na admixtures oqo e rawa ni vakatorocaketaka na bula balavu ni simede, vakalailaitaka na isau ni kena maroroi kei na vakayagataki ni ivurevure me baleta na veivale. E vuqa na admixtures cecere-vakalailaitaka na wai era sa rawata talega na veivakadonui ni veimatanitu ni veivanua, aligning kei na takete ni veivakatorocaketaki tudei ni tara vale drokadroka.
Ena kena tomani tikoga na kena vakatorocaketaki na tekinolaji ni tara vale, na kena vakayagataki na admixtures ni wai-vakalailaitaka sa vakarabailevutaki talega. Me kena ivakaraitaki, ena simede cecere-cakacaka (HPC) kei na simede vakataki koya (SCC), na wai-vakalailaitaka na admixtures era additives bibi ka vakadeitaka na iyau ni vakatautauvatataki vakataki koya ni simede ena ruku ni cecere ni density kei na ituvaki ni kaukauwa. Me kena ikuri, na wai-vakalailaitaka na veiwaki e rawa ni vakayagataki vata kei na veiwaki tale eso (me vaka na retarders kei na cagi-vakacurumi) me vakavinakataki cake kina na iyau ni simede.
Ena cakacaka ni tara vale, na vakayagataki ni wai-vakalailaitaka na admixtures e rawa ni vakalevutaka sara vakalevu na kaukauwa ni compressive kei na wai ni simede, vakabalavutaka na bula ni veiqaravi ni veivakatorocaketaki. Me kena ivakaraitaki, ena kena tara na veivale cecere kei na idrodro lelevu, na admixtures cecere-vakalailaitaka na wai e vakadeitaka na flowability vinaka ni simede ena ruku ni gagadre cecere-kaukauwa, vakarawarawataka na cakacaka ni taravale.
