Kubva pamharadzano iyi ona kushandiswa kweLimestone. Ratidzai migumisiro yacho muchimiro cherondedzero ine nhamba.
Context:Limestone (calcium carbonate CaCO3) rudzi rwekarbonate sedimentary rock inova ndiyo sosi huru yeiyo lime. Inonyanya kuumbwa nemaminerari anonzi calcite uye aragonite, ayo ari marudzi akasiyana emakristaro eCaCO3. Dombo rechimera rinoumbwa kana zvicherwa izvi zvikabuda mumvura ine calcium yakanyungudutswa. Izvi zvinogona kuitika kuburikidza nemaitiro ezvisikwa uye asiri ehupenyu, kunyangwe zviitiko zvehupenyu, senge kuunganidzwa kwemakorari nemakomba mugungwa, zvingangove zvakakosha zvakanyanya mumakore ekupedzisira emamirioni mazana mashanu nemakumi mashanu. Dombo reLime rinowanzo kuve nezvakawanikwa izvo zvinopa masayendisiti ruzivo nezvezvakatipoteredza zvekare uye nekushanduka kwehupenyu. Inenge 20% kusvika 25% yedombo remarara idombo recarbonate, uye mazhinji acho idombo reLime. Dombo reCarbonate rakasara rinowanzo kuve dolomite, dombo rakabatana zvakanyanya, iro rine chikamu chakakura che mineral dolomite, CaMgC0O3 ((2). Magnesian limestone ishoko rakapera uye risina kunyatso tsanangurwa rinoshandiswa zvakasiyana-siyana kune dolomite, kune dombo rine dolomite yakakosha (dolomitic limestone), kana kune chero rimwe dombo rine chikamu chakakosha che magnesium. Dombo reLime rakaumbwa munzvimbo dzisina kudzika, senge mahwendefa emakondinendi kana mapuramu, kunyangwe zvidiki zvidiki zvakaumbwa Zvizhinji zve dolomite inonzi secondary dolomite, yakaumbwa nekushanduka kwemakemikari kwebwe relimestone. Mapako mazhinji anowanikwa mumatombo emarara. Matombo emarara ane mashandisirwo akawanda: semakemikari ekugadzira lime rinoshandiswa kugadzira simende (chinhu chinokosha chekongiri), sechinhu chinogadziriswa pasi pemigwagwa, sechinhu chena kana kuzadza mune zvigadzirwa zvakadai semazino mazino kana pendi, sechinhu chinogadzirisa ivhu, uye sechinhu chinoshongedza chakakurumbira muminda yematombo. Matombo anogadzirwa nematombo erima ane inenge 30% yenzvimbo dzinochengeterwa peturu pasi pose.
