Ukususela kwiminyaka yee-1940,ucingo lomnatha isamenteyaqala ukusetyenziswa kwishishini lokwakha iinqanawa.Okwangoku, ayisetyenziselwanga kuphela ukwakha iinqanawa, kodwa kunye noluhlu olubanzi lweenkxalabo.Kuyaziwa ukuba i-calcium oxide yasimahla kwi-clinker yesamente ichaphazela uzinzo, kuba i-calcium oxide yasimahla iqala ukumanzisa emva kokuqina kwesamente, umthamo wemveliso yebhiliyoni yamanzi (i-calcium hydroxide) ukwandisa amaxesha angama-1.5 ~ 2.0, ukuze ukugqabhuka kwesamente ukuqina komzimba, okukhokelela kuzinzo olulambathayo lwesamente.
Ngoko ke, kunokuqwalaselwa ukuba ukuba i-calcium oxide yamahhala kwi-samente iqinisa ukungabikho kwe-hydration kwixesha elizayo, ngoko ayiyi kubangela ingxaki yokuzinza kwe-samente embi.Idatha efanelekileyo ibonisa ukuba umphumo we-calcium oxide yamahhala kwi-kiln ash kwi-stability ilula kakhulu kune-calcium oxide yamahhala kwi-clinker.Kuyabonakala ukuba izinga lokugalela amanzi kwiintlobo ezimbini ze-calcium oxide yasimahla yahlukile.Izinga le-hydration ye-calcium oxide yamahhala kwi-kiln ash ikhawuleza.Esinye sezizathu kukuba ubushushu bobushushu be-ash ye-oven bungaphantsi kune-clinker kwaye uthuthu lwe-kiln lukwimo evuthayo.Ukukhanya okutshisa i-calcium oxide kulula ukugalela amanzi kunobushushu obuphezulu be-calcined calcium oxide.
Isigqubuthelo sincinci kwisimo sokusongwa.Umxholo we-calcium oxide yamahhala kwi-ash ye-kiln iphezulu, kwaye kulula uku-hydrate ukuvelisa i-calcium hydroxide kunye ne-gravity encinci ethile, echaphazela nefuthe layo lemvula kumanzi ajikelezayo.Isetyenziswa kubunjineli bokwakha, ubunjineli behydraulic, ulwakhiwo lweemveliso kunye nemesh yocingo yi ~ yokwakheka kwemathiriyeli yesamente enemesh, yinto eyomeleziweyo eyomeleziweyo, ukuhanjiswa okufanayo kwizinto ezinqabileyo (udaka lwesamente), eTaiwan ngodaka lwesamente. , amandla xa i-deformation edibeneyo, kunye ne-li ifuthe omnye komnye, inika umdlalo opheleleyo kwiimpawu zemathiriyeli edibeneyo, Iindidi ezininzi ze-composites ezineempawu ezibalaseleyo zenziwe.
