Kugwirizana pakati pa zosakaniza ndi simenti:

Ntchito yayikulu ya ma admixtures ndikuwongolera magwiridwe antchito a konkriti powonjezera zosakaniza zofananira ku konkriti, potero kulimbikitsa kupititsa patsogolo kwa zomangamanga komanso magwiridwe antchito a zomangamanga. Chifukwa chomwe ma admixtures amatha kulimbikitsa kusintha kwa zinthu zosiyanasiyana za konkire ndikuti amatha kubweretsa zolumikizana ndi konkriti. Nthawi zambiri, zomwe zimayenderana pakati pa zosakaniza ndi konkire zimasinthika, zofananira komanso zogwirizana. Popeza zigawo zikuluzikulu ndi kuchuluka kwa zigawo zosiyanasiyana mu admixtures ndi zosiyana, kusinthasintha pakati admixtures osiyana ndi konkire adzakhalanso osiyana kwambiri. Zosakaniza zokhala ndi kusinthasintha kosasintha sizingangowonjezera kutsika kwa madzi a konkire, komanso zimapangitsa kuti konkire ikhale yofulumira kwambiri, motero imakhudza kumanga kwabwino kwa polojekitiyi. Zosakaniza zokhala ndi zosinthika zabwino zimatha kusintha bwino kuchuluka kwa madzi a konkire ndikupewa kusweka ndi kusweka kwa konkriti pamlingo wina. Kufananiza kwa zosakaniza ndi konkire kumakhudzanso mphamvu ya adsorption ya konkriti kuti admixtures. Ngati mafananidwe a admixtures ndi konkire ndi otsika, ndi adsorption dzuwa la konkire kuti admixtures adzakhala otsika kwambiri, zomwe zidzakhudzanso zosiyanasiyana zotsatira zake admixtures. Kugwirizana kwa zosakaniza ndi konkire zidzakhudza mphamvu ya ntchito admixtures. Ngati kugwirizana kwa zosakaniza ndi konkire ndizosauka, konkire sangathe kusakanikirana ndi admixtures, zomwe zingayambitse kuwonongeka kwa zosakaniza zina.

Malingaliro pazosankha zophatikizira konkriti zophatikizika:

1. Opanga konkriti admixture ayenera kukhala ndi ntchito zabwino zogulitsa zisanachitike komanso zogulitsa pambuyo pake. Pamene kugulitsa konkire admixtures, konkire admixture opanga ayenera kuganizira zinthu zofunika, kukhazikitsa ndi wathunthu konkire admixture zikalata luso mmene ndingathere, kupereka konkire admixture malangizo, ndi kuonetsetsa kuti kugulitsa konkire admixtures ikuchitika mkati mwa kukula kwa kupezeka thandizo luso.

2. Sankhani bwino admixture khalidwe. Posankha premixed konkire admixtures, m'pofunika kudziwa mwatsatanetsatane ntchito mitundu ndi Mlingo wa admixtures. Pezani zophatikizira zofananira zofananira ndi konkriti, sankhani zosakaniza zapamwamba momwe mungathere, ndipo sewerani gawo la zosakaniza za konkriti.

3. Sankhani metering chiwembu choyenera kupanga zokha. Kusankha metering chiwembu choyenera kupanga zochita zokha ndi imodzi mwa mfundo zofunika kusankha premixed konkire admixtures.

4. Kusankha admixtures ndi phindu lalikulu lazachuma Kusankhidwa kwa admixtures ndi phindu lalikulu ndikukwaniritsa bwino zomanga ndi kupanga zofunikira zamagulu omanga. Iyenera kukhala yogwirizana ndi momwe mayunitsi omanga alili pano, kukhala ndi mikhalidwe yowunikira bwino, kukwaniritsa zofunikira pazachuma za magawo omanga pamlingo wina wake, ndikukhala ndi zopindulitsa pazachuma. Chifukwa chake, chiwembu chosankha chophatikizachi chimadziwika kwambiri ndi magawo omanga.
