Zosakaniza za konkire zimagwiritsidwa ntchito kwambiri m'nyumba, kotero ubwino wa zosakaniza za konkire zimakhudza kwambiri khalidwe la polojekitiyi. Wopanga konkriti wochepetsera madzi amawonetsa kusauka kwa zosakaniza za konkriti. Mavuto akadzapezeka, tidzawasintha.

Choyamba, kukhazikika kwachilendo kumachitika panthawi yosakaniza konkire yatsopano, monga kukhazikika kofulumira, malo onama ndi zochitika zina, zomwe zimayambitsa kutayika kwachangu.

Chachiwiri, kutuluka kwa magazi, kulekanitsa ndi stratification ya konkire ndizovuta, ndipo mphamvu zowumitsa mwachiwonekere zimachepetsedwa.

Chachitatu, kugwa kwa konkire yatsopano sikungawongoleredwe, ndipo zikuwoneka kuti kuchepetsa madzi kwa zowonjezera za konkire ndizosauka.

Chachinayi, shrinkage ya konkire imawonjezeka, impermeability ndi durability kuchepa, ndipo zotsatira retarding mu lalikulu dera konkire si zoonekeratu, ndi kutentha kusiyana ming'alu kuonekera.

Zosakaniza za konkriti zimatha kubweretsa kumasuka kwambiri pakumanga, ndipo zakhala zikugwiritsidwa ntchito kwambiri pantchito yomanga. Tayambitsa kale kusankha konkriti admixtures kale. Apanso tikugogomezera kusankha kwa zowonjezera.

1. Mtundu wa admixture udzasankhidwa malinga ndi zomangamanga ndi zomangamanga zofunikira, ndiyeno zimatsimikiziridwa molingana ndi mayesero ndi kufananitsa koyenera kwaukadaulo ndi zachuma.

2. Ndizoletsedwa kugwiritsa ntchito zosakaniza za konkire zomwe zimawononga thupi la munthu ndikuipitsa chilengedwe.

3. Pazinthu zonse za simenti ya konkriti, timalimbikitsa kugwiritsa ntchito simenti ya Portland, simenti ya Portland wamba, simenti ya slag Portland, simenti ya pozzolanic Portland, simenti ya phulusa la Portland ndi simenti ya Portland. Malangizo ofunda: tiyenera kuyang'ana bwino kusinthasintha kwa ma admixtures ndi simenti musanagwiritse ntchito.

4. Zida zomwe zimagwiritsidwa ntchito pogwiritsira ntchito zosakaniza za konkire ziyenera kukwaniritsa zomwe zilipo. Pamene mayesero kusakaniza konkire admixture, tiyenera kugwiritsa ntchito zopangira pulojekiti, kutengera momwe polojekitiyi ikuyendera.

5. Mukamagwiritsa ntchito mitundu yosiyanasiyana ya zosakaniza, chidwi chapadera chiyenera kuperekedwa pakugwirizana kwawo ndi zotsatira za ntchito ya konkire. Kusankhidwa kosakaniza konkire kumatsindikanso, zomwe zimasonyeza kufunika kwake ndikuyembekeza kukhala zothandiza kwa aliyense.
