Aggregate amatenga voliyumu yaikulu ya konkire, koma kwa nthawi yaitali, pali kusamvana zambiri za muyezo kuweruza khalidwe aggregate, ndipo kusamvana chachikulu ndi chofunika yamphamvu compressive mphamvu. Kusamvetsetsana uku kumachokera ku gawo lake mu konkire, ndiye kuti mchenga ndi miyala, monga mafupa aumunthu, ndizofunika kwambiri kuti mudziwe mphamvu ya konkire. Choncho, mabuku ambiri ndi mfundo zambiri zamakono ndi zikhalidwe zimafunabe mphamvu zamagulu kuti zikhale 1.5 mpaka 1.7 nthawi, kapena 2 nthawi mphamvu ya konkire yokonzeka. Wolembayo amakhulupirira kuti pamene konkriti koyambirira kalasi yopangira akadali otsika kwambiri, chofunikira ichi chimayikidwa patsogolo, ndiko kuti, mphamvu ya cylinder compressive ya aggregate ndi ≥40MPa, zomwe mwachiwonekere ndikungochotsa miyalayi ndi nyengo yotentha ngati yophatikiza; Komabe, mphamvu zamapangidwe a konkire zakhala zikuyenda bwino kwambiri, ndipo zimatsatirabe ubale wapakati pa awiriwa, zomwe mwachiwonekere zasudzulana kwambiri ndi zenizeni. M'malo mwake, konkire yopepuka yopepuka kunyumba ndi kunja yakonzedwa ndikuigwiritsa ntchito ku uinjiniya, ndipo mphamvu yopondereza ya silinda yamagulu opepuka omwe amagwiritsidwa ntchito ndi 15MPa kapena kutsika, pomwe mphamvu ya konkire imatha kufikira 80 mpaka 100MPa.

Lingaliro lina lolakwika ndi kukula kwa tinthu ting'onoting'ono komwe kumagwiritsidwa ntchito pa miyala ya konkire yopopera kapena miyala yodzipangira yokha (SCC). Popeza payenera kukhala kuyenda wachibale pakati pa miyala mu ndondomeko ya kusakaniza woteroyo kuyenda mu mpope chitoliro ndi kuyenda mu Chinsinsi, ndi thicker matope kondomu filimu wosanjikiza chofunika kayendedwe wachibale pakati pa mwala particles ndi zazikulu tinthu kukula, ndiko kuti, kwambiri. kuchuluka kwa zamkati kungafunike. Ichi ndi chifukwa chake 19mm(British 3/4inch) ndi kukula kwa tinthu tating'ono ta miyala yomwe imagwiritsidwa ntchito pokonzekera zosakaniza zotere kunja. Ngakhale kuti tinthu tating'onoting'ono ta miyala yomwe imagwiritsidwa ntchito ndi yaying'ono, chiŵerengero chopanda kanthu chomwe chiyenera kudzazidwa mu kusakaniza ndi chachikulu, chomwe chilipo pakati pa zomwe zili pamwambazi, ndipo kuchuluka kwa matope omwe amafunikira kusakaniza ndi kochepa.
