Kuphatikizira kosakanikirana koyenera ku konkriti kumatha kupititsa patsogolo kulimba koyambirira komanso kugwira ntchito mwamphamvu kwa konkriti. Konkire wothira mphamvu yoyambira nthawi zambiri amakhala ndi mphamvu zoyambira; kuwonjezera mlingo woyenera wa madzi ochepetsera pamene kusakaniza kusakaniza kungachepetse kuchuluka kwa madzi. Pamene chiŵerengero cha simenti yamadzi ndi chochepa, chimatha kuonetsetsa kuti konkire imapangidwa bwino ndipo mphamvu yapamwamba ya 28d ingapezeke. Zosakaniza zimatha kupititsa patsogolo kachulukidwe wa simenti, kukulitsa kumamatira pakati pa zophatikiza ndi simenti, ndikuwonjezera mphamvu yayitali ya konkriti. Chifukwa chake, ngati mukufuna kupititsa patsogolo mphamvu ndi magwiridwe antchito a konkriti, mutha kuganiziranso kuwonjezera zochepetsera bwino kwambiri zamadzi ndi kusakaniza mukasakaniza kusakaniza.
Chochepetsera madzi chimakhala ndi ubwino wokonza konkire yogwira ntchito, kuchepetsa kugwiritsa ntchito madzi, kuonjezera mphamvu, ndi kupititsa patsogolo kukhazikika kwa konkire. Komabe, mu njira yowerengera kuchuluka kwa madzi ochepetsera madzi, n'zosavuta kunyalanyaza kutsekemera kwa zipangizo za ufa mumagulu a konkire pa zochepetsera madzi. Madzi ochepetsera madzi a konkire yamphamvu yotsika ndi otsika, ndipo zinthu za ufa pamagulu onse sizikwanira pambuyo pa adsorption. Komabe, mlingo wochepetsera madzi wa konkire wamphamvu kwambiri ndi waukulu kwambiri, ndipo kuchuluka kwa adsorption ufa mumagulu onse sikusiyana kwambiri ndi ufa wochepa mphamvu, zomwe zidzachititsa kuti madzi ochepetsetsa achepetse mphamvu.
Popanga chiŵerengero cha kusakaniza, mlingo wochepetsera madzi ndi wolondola, osati wochuluka kapena wochepa kwambiri, womwe ndi wosavuta kulamulira kupanga ndikuwonetsetsa kukhazikika kwa khalidwe la konkire. Ichi ndi cholinga chotsatiridwa ndi akatswiri a konkire. Komabe, kaya zopangira konkriti zomwe zimagwiritsidwa ntchito ndi zachilengedwe kapena zopangira, zida zina za ufa zimabweretsedwa mosalephera. Choncho, popanga chiŵerengero chosakanikirana, zipangizo za ufa za konkriti zopangira ziyenera kuganiziridwa powerengera mlingo wochepetsera madzi.
Musanayambe kuwerengera mlingo wochepetsera madzi, mlingo wosakaniza ndi madzi ochepetsera mlingo wa konkire wa benchmark umatsimikiziridwa ndi zoyesera, ndiyeno kuchuluka kwa ufa wa konkire kumawerengedwa molingana ndi chiŵerengero cha kusakaniza konkire, ndipo mlingo wochepetsera madzi umawerengedwa; ndiye mlingo wowerengeka umagwiritsidwa ntchito kuwerengera mlingo wochepetsera madzi wa magulu ena amphamvu.
Pogwiritsa ntchito mchenga wopangidwa ndi makina ambiri komanso kuwonjezeka kwa zinthu za ufa, ufa umatenga kapena kuwononga madzi enaake. Kuwerengera kuchuluka kwa zochepetsera madzi pogwiritsa ntchito ufa wokwanira wa zinthu zopangira konkriti ndikosavuta kuwongolera ndipo ndi sayansi.
