Warshadaha qalabka dhismaha, budada kaalshiyamka qaabaysan oo leh cabbir guud oo ah 13 mm ayaa badanaa lagu daraa hoobiyaha sibidhka caadiga ah oo leh saamiga 0.3% ilaa 0.8% miisaanka sibidhka, iyadoo la oggol yahay hagaajinta iyadoo lagu saleynayo kala duwanaanshaha heerkulka. Dhismaha darbiga daahyada ee Xarunta Maaliyadda Adduunka ee Shanghai, ku darista 0.5% kaalshiyam qaabaysan inta lagu jiro dhismaha jiilaalka ayaa u suurtagelisay koollada sibidhka inay gaaraan 108% xoogga tixraaca 3 maalmood gudahood. Habka hoose wuxuu ku lug leeyahay dardargelinta hydrolysis-ka silicate tricalcium silicate si loo soo saaro kaalshiyam silicate hydrate (CSH), taasoo dedejinaysa adkaynta iyo koritaanka kiristaalka. Shaqadeeda ka hortagga barafowga waxay ka timaaddaa saameynta cadaadiska osmotic, taas oo kor u qaadaysa barta barafowga ee marxaladda dareeraha. Mashaariicda dayactirka degdega ah ee wadada jiilaalka ee waqooyiga Shiinaha, habkani wuxuu muujiyay faa'iidooyin dhaqaale isagoo yareynaya waqtiga bogsashada 55% inta lagu jiro dhismaha.
