Admixtures ustooje ndiyam toowɗe : ɓeydude golle beton ngam mahngo leɗɗe
Fannuuji kuutoragol mawɗi
Kosam ɗam ustata ndiyam toowɗam (hono kosam ɗam polikarboksilaat) ina hollita sifaa ɓurɗo yaajde e ko ustata ndiyam tawa ina woodi e luumo hee. Eɗe ngolloo e waɗde laral diƴƴe e dow ɗaɗol semmbe, haɗde mooftude ɗaɗol semmbe, ɗum noon ɓeyda ɓuuɓde e golloraade beton. Ngaal batte diisnondiral wonaa tan ustude njaru ndiyam kono kadi ina ɓeyda ɓuuɓri e semmbe beton. So en tuugniima e mbaydiiji gaadanteeji ustooji ndiyam, mbaydiiji toowɗi ina ndokka ustaare ndiyam ɓurnde toowde (ko ɓuri heewde ko 25%-40%) e doseeji ɓurɗi famɗude (ko ɓuri heewde ko 0,1%-0,3% e keewal geɗe semmbeeji), tawa batte mum en ina pamɗi e weeyo.
E nder eɓɓaaɗe mahngo, huutoraade mbaydiiji ustooji ndiyam ina waawi ɓeydude no feewi semmbe ɓuuɓɗo e ɓuuɓgol ndiyam e beton, ɓeyda nguurndam gollal mbaydiiji. Yeru, e nder mahngo galleeji toowɗi e ponte mawɗe, mbaydiiji ustooji ndiyam toowɗi ina ɗaɓɓi ɓuuɓri moƴƴiri e beton e nder sarɗiiji semmbe toowɗo, ina newna golle mahngo. Yanti heen, ɓuuɓri ustooji ndiyam ina mbaawi ustude ƴiiƴam e seerndude e nder beton, ɓeyda ngootaagu e jokkondire mum.
E nder fannu mahngo leɗɗe, sifaaji weeyo ɗi mbaydiiji ustooji ndiyam ina teskaa. Huutoraade mbaydiiji ustooji ndiyam toowɗi ina waawi ustude njaru semmbe, ɗum noon ina usta mboros karbon. Yanti heen, ɗeen jillondirɗe ina mbaawi ɓeydude duumingol beton, ustude njoɓdi toppitagol e huutoraade ngalu ngam mahngo. Ko heewi e mbaydiiji ustooji ndiyam toowɗi keɓii kadi seedanteeje winndereeje to bannge taariindi, tawa ina yahdi e paandaale ƴellitaare duumotoonde mahngo leɗɗe.
E jokkude ƴellitaare karallaagal mahngo, kuutoragol mbaydiiji ustooji ndiyam ina ɓeydoo kadi yaajde. Yeru, e nder beton toowɗo (HPC) e beton cemmbinoowo hoore mum (SCC), ɓuuɓri ustooji ndiyam ko ɓeydooje teeŋtuɗe baawɗe tabitinde sifaaji cemmbinɗi hoore mum beton e nder ngonkaaji toowɗi e semmbe. Yanti heen, ɓuuɓri ustooji ndiyam ina waawi huutoreede e ɓuuɓri goɗɗi (ko wayi no ɓuuɓri e ɓuuɓri gonndi e henndu) ngam ɓeydaade moƴƴinde sifaaji beton.
