Zotsatira zamakina zopangidwa ndi mchenga komanso kusunthika kosakanikirana pa mtundu wa konkriti

Mayi a Rock ndi Rock Technolognology ya mchenga wopangidwa ndi makina mu zigawo zosiyanasiyana ndizosiyana kwambiri. Mphende yamchere yamakina yopangidwa ndi makina imakhudzanso kuchepa kwa konkriti pamchenga wopangidwa ndi matope mu mchenga wopangidwa ndi madoko, makamaka kubwerera konkriti. Kulimbana ndi mphamvu komanso kukhazikika, zomwe zimapangitsa kuti pakhale papang'onopang'ono la ufa pa konkriti, komanso osavomerezeka chifukwa cha kuwongolera mtengo wosakanikirana. Chisangalalo cham'madzi chomwe chimapangidwa pano ndi 3.5-3.8, kapena ngakhale 4.0, ndipo ma gradation amathyozedwa bwino komanso wopanda nzeru. Gawo lomwe lili pakati pa 1.18 ndi 0.03mm ndizochepa kwambiri, zomwe zimakhala zovuta kupompa konkriti.

1. Pakangopanga mchenga wopangidwa ndi makina, zomwe zili pamwala uyenera kulamulidwa mosamalitsa kukhala pafupifupi 6%, ndipo zomwe zili m'matope ziyenera kukhala mkati mwa 3%. Zomwe zili mwala wamiyala ndi zowonjezera bwino za mchenga wosweka.

2. Pokonzekera konkriti, yesani kusunga mwala wina wa miyala kuti mukwaniritse kuchuluka kwamphamvu, makamaka kuwongolera kuchuluka kwa 2.36mm.

3.

4. Mchenga wamachiyu wotsuka umagwiritsa ntchito molimbika poyendetsa ndi kuchotsa matope, komanso gawo limodzi la malo ogona lidzakhalabe mumchenga womalizidwa. Kulemera kwambiri kwa thupi kumalimbikitsa kwambiri pamadzi ochepetsa madzi, ndipo madzi ndi kuchepa kwa konkritiyo ndi yayikulu kwambiri.

Mphamvu yogwiritsitsa ndi kusinthitsa kosakanikirana pa mtundu wa konkriti

Mphamvu Yobzala phulusa ili kale, ndipo phulusa lauluka limabadwa. Mabizinesi okhala ndi chikumbumtima chabwino chidzawonjezera kuchuluka kwa phulusa laiwisi. Mabizinesi akuda alimi ndi mwala. Chachikulu, ntchitoyi ndi 50% mpaka 60%. Kuchuluka kwa ufa wa miyala yamtengo wophatikizidwa ndi phulusa la ntchent sikungokhudzanso kuwonongeka kwa phulusa lauluka komanso kumakhudza ntchito yake.

1. Limbikitsani kuyang'ana pakukula phulusa, yikani kusintha kwa kutaya kwake poyatsira, ndipo samalani ndi madzi omwe amafunikira.

2. Kuchuluka kwa chipatala kumatha kuwonjezeredwa moyenerera kwa phulusa lauluka kuti awonjezere ntchitoyi.

3. Ndi zoletsedwa kugwiritsa ntchito gangue kapena shale ndi zinthu zina zomwe zimakhala ndi madzi othamanga kwambiri kuti athe kupera phulusa.

4. Kuchuluka kwa zinthu zokhala ndi zosakaniza zamadzi kumatha kuwonjezeredwa ndi phulusa lauluka, zomwe zimapangitsa kuti kuwongolera madzi kumathandizanso.
