Kubva kuma1940,waya mesh simendeyakatanga kushandiswa muindasitiri yekuvaka ngarava.Parizvino, haisi kushandiswa chete pakuvaka zvikepe, asiwo zvakasiyana-siyana zvekunetseka.Zvinonyatsozivikanwa kuti iyo yemahara calcium oxide mu simende clinker inokanganisa kugadzikana, nekuti yakasununguka calcium oxide inotanga kunyorova mushure mekuoma simende, vhoriyamu yemvura yayo bhiriyoni zvigadzirwa (calcium hydroxide) kuwedzera 1.5 ~ 2.0 nguva, kuitira kuti iyo simende inoomesa muviri kuputika, zvichikonzera kusagadzikana kwesemende.
Naizvozvo, zvinogona kurangarirwa kuti kana mahara calcium oxide mu simende kuomesa ramangwana kushaya hydration, saka hazvizokonzeri dambudziko rekushaya simende kugadzikana.Iyo data yakakodzera inoratidza kuti mhedzisiro yemahara calcium oxide muchoto madota pakugadzikana yakareruka kupfuura iyo yemahara calcium oxide mu clinker.Zvinogona kuonekwa kuti hydration rate yemhando mbiri dzemahara calcium oxide yakasiyana.Iyo hydration rate yemahara calcium oxide muchoto madota inokurumidza.Chimwe chezvikonzero ndechekuti tembiricha yekudziya yedota remoto yakadzikira pane yeclinker uye dota remoto rinenge richipisa.Chiedza chinopisa calcium oxide chiri nyore kuita hydrate pane icho chepamusoro tembiricha calcined calcium oxide.
Iyo yekupfeka ishoma mumamiriro ekuputirwa.Izvo zvirimo zvemahara calcium oxide muchoto madota zvakakwirira, uye zviri nyore hydrate kuburitsa calcium hydroxide ine diki chaiyo giravhiti, iyo inokanganisawo kunaya kwayo mukutenderera kwemvura.Inoshandiswa mukuvaka engineering, hydraulic engineering, chimiro chezvigadzirwa uye waya mesh ndiyo ~ yekuumbwa kwesimbi mesh simende zvinhu, inosimba yakasimbiswa zvinhu, yunifomu kugovera mune brittle zvinhu (simende dhaka), Taiwan iyo nesamende dhaka. , iyo simba apo mubatanidzwa deformation, ine li inopesvedzera mumwe nemumwe, inopa kutamba kwakazara kune hunhu hwechinhu chinoumbwa, Mhando dzinoverengeka dzemakombiki ane hunhu hwakanaka anoumbwa.
