Pofuna kuthetsa vuto la kusagwirizana pakati pa admixtures ndi simenti, cholinga chake ndi kupewa, kusankha zipangizo ndi kuzindikira zinthu zomwe zikubwera. Kusinthasintha kwa admixtures ndi simenti ndi vuto lovuta, ndipo vuto la kusagwirizana pakati pa admixtures ndi simenti limapezeka. Opanga konkire amatenga nthawi yake: malinga ndi momwe zinthu ziliri, kutengera zoyeserera, santhulani ndikupeza zifukwa, sinthani chiŵerengero cha konkire chosakanikirana, ndikuwongolera fakitale. slump, kuchepetsa slump loss.It nthawi zambiri zofunika kusintha kuchuluka kwa ntchentche phulusa, kuonjezera kuchuluka kwa admixtures, kuwonjezera madzi gawo zotsalira za admixture mu konkire, kusunga madzi simenti.
chiŵerengero chosasinthika, ndi kuonjezera kuchuluka kwa simenti, zomwe mosakayikira zimawonjezera mtengo wa unit. Kapena njira yowonjezera yowonjezera ikhoza kutengedwa, ndiko kuti, kugwa kwa fakitale kumayendetsedwa pa 80-100, ndipo yankho la admixture limalimbikitsidwa mwamphamvu kwa mphindi 2 kuti lizolowere 140 musanagwiritse ntchito pamalo omanga, omwe ndi okwera mtengo kwambiri. ndi ogwira. Opanga konkire nthawi zambiri amafunikira zowonjezera kuti agwirizane ndi simenti chifukwa cha kuchuluka kwakukulu kwa simenti, ndiko kuti, opanga ma admixture amayenera kusintha mawonekedwewo, malinga ndi simenti yogwiritsidwa ntchito ndi opanga konkire kuti asinthe mitundu ndi kuchuluka kwa zochepetsera madzi ndi retarders. mu zowonjezera, kapena kuwonjezera kuchuluka kwa Plasticizer, mpweya-entraining wothandizira popanda thovu, etc.
Kutsimikiza kwa chiŵerengero cha kusakaniza konkire kumafunikanso kuganizira nthawi ya coagulation ya konkire, kusakaniza kumakhala ndi zosakaniza zowonongeka, kutentha kumatsika mwadzidzidzi pa kutentha kwakukulu, kusakaniza konkire kumakhala kochuluka kwambiri, ndipo chilinganizocho sichinasinthidwe. m'kupita kwa nthawi, zomwe zimabweretsa kulephera kwa nthawi yayitali kwa konkire. Condensation idzakhudza kwambiri mphamvu ya konkire. M'chilimwe, kumanga kuyeneranso kupewa masana kutentha ndi mphepo, ndikuziziritsa zopangira. Kutsimikiza kwa chiŵerengero cha mchenga mu chiŵerengero cha kusakaniza konkire chiyeneranso kusinthidwa molingana ndi kukula kwa mchenga wabwino ndi porosity ya coarse aggregate. ndipo kutaya kungachepe.
