Lightweight Concrete Additives | High-Performance Foaming Agents for Cellular Concrete
Foam kongiri inzira nyowani yekuvaka inosanganisa jecha, aggregates uye simende ine furo kugadzira agent kuti ibudise huremu, self-compacting uye yakasimba kongiri. Iyo inodururwa muforoma kana fomu uye inogona kutemwa kune akasiyana saizi kuti ishandiswe muzvinhu zvakaumbwa senge matanda., slabs uye madziro. Foam kongiri inogona kushandiswa panzvimbo yemhando dzechinyakare kana dhaka uye yakareruka kupfuura yakajairwa kongiri nekuda kweiyo thixotropic zvivakwa. (kugona kuyerera semukaka) iyo inotorwa kubva mukudyidzana pakati pemafuro efuro nejecha uye akaunganidzwa mumusanganiswa.
Kushanda kwekongiri yefuro kunoenderana nechiyero chemvura-simende uye rudzi rweaggregates. Iyo yakakwirira yehuwandu hwemvura-simende, mvura yakawanda iyo kongiri uye zviri nyore kudurura. Zvisinei, apo w/c chiyero chiri pamusoro pemuganho wakakwana, foam kongiri ine madziro akatetepa uye asina kujairika pores anokura. Izvi zvinokanganisa simba rekumanikidza nekuti ma pores anoiswa pasi pekunetsekana [5,15]. Kushandisa supplementary binder components kunovandudza kushanda. Izvi zvinosanganisira madota enhunzi, geocement uye alkaline Portland simende. Fly ash ndiyo inonyanya kushandiswa sezvo inoderedza huwandu hwesimende inoshandiswa uye kupisa kwayo kwe hydration, izvo zvinotungamirira kukuwedzera kwekushanda. Pamusoro pe, iyo spherical chimiro chenhunzi ash inowedzera kuyerera kwekongiri uye maitiro ayo e hydration.
Kushandiswa kweRCA sechinzvimbo chejecha kunowedzera kushanda uye mashandiro emagetsi efoam concrete, uye zvakare inowedzera porosity nekuda kwekuita kwayo kusina chinhu. Zvisinei, ine mhedzisiro yakaipa pakuomesa shrinkage uye kunyura kwemvura.
