Chloride ion ndi gawo loyipa la simenti ndi zopangira simenti.Zimakhudza mwachindunji preheater ndi uvuni calcination mu njira yatsopano youma kupanga simenti, zomwe zimabweretsa ngozi monga mapangidwe a mphete ndi plugging, zomwe zimakhudza mlingo wa ntchito ya zida ndi khalidwe la simenti ya simenti. mtengo wina, udzawononga chitsulo chachitsulo mu konkire, kuchepetsa mphamvu yazitsulo zachitsulo, kungayambitsenso kuwonongeka kwa konkire chifukwa cha kukula, ndipo pamene kuli kwakukulu, kumayambitsa kuphulika kwa konkire ndikukwirira zoopsa zobisika za khalidwe la polojekitiyi, kuyenera kuyendetsedwa mosamalitsa.Zofunikira za kuchepa kwa ayoni wa kloridi zawonjezeredwa m'nkhani 7.1 ya GB 175-2007 Common portland simenti.
Chofunikira ndichakuti chloride zili mu simenti siziposa 0.06%. Njira ya ammonium thiocyanate volumetric, njira ya potentiometric titration ndi njira ya ion chromatography imagwiritsidwa ntchito pozindikira ayoni a kloride.Komabe, chifukwa kukhazikika kwa siliva chloride sikwabwino, kapangidwe ka siliva (klorini) elekitirodi ndi yosakhazikika, ndipo kukhudzidwa kwa chilengedwe kumakhala kokulirapo, kumabweretsa kusabwereza bwino komanso koyenera kuzindikira zinthu zomwe zili ndi chloride yayikulu.Ion chromatography, monga njira yabwino yodziwira zinthu za ayoni, zitha kugwiritsidwa ntchito kusanthula ma ion angapo nthawi imodzi ndi jekeseni imodzi, ndipo imakhala ndi mawonekedwe achangu komanso olondola.
Papepalali, ion chromatography imagwiritsidwa ntchito kusanthula ndi kuyesa zowonjezera za konkriti ndi ion chloride mu simenti.
