Kodi konkriti yopindika imapangidwa ndi chiyani?

Konkire yowonongeka, yomwe imadziwikanso kuti konkire yowonongeka kapena konkire ya porous, imapangidwa pogwiritsa ntchito kusakaniza kwa simenti, kuphatikiza ndi madzi, mofanana ndi konkire wamba. Komabe, pofuna kukwaniritsa permeability, pali kusiyana kwakukulu mu kapangidwe kake. Kusiyanitsa kwakukulu ndiko kugwiritsa ntchito magulu akuluakulu ndi kuchepa kwa tinthu tating'onoting'ono tomwe timasakaniza. Izi zimapanga mipata yayikulu kapena mipata mkati mwa konkire yomwe imalola madzi kudutsa mosavuta. Kuphatikizika komwe kumagwiritsidwa ntchito kumatha kukhala kwamitundu yosiyanasiyana monga mwala wophwanyidwa, miyala kapena zinthu zopepuka zopepuka. Kuonetsetsa mphamvu ndi kulimba kwa permeable konkire, simenti ndi madzi kukhala zinthu zofunika. Simenti imakhala ngati chomangira kuti chigwirizanitse pamodzi, pamene madzi ndi ofunika kuti hydration iwonongeke panthawi yochiritsa. Kuphatikiza pa zosakaniza zokhazikika za konkriti, konkriti yowonongeka imatha kukhala ndi zowonjezera zina kapena zosakaniza. Zowonjezera izi zimakulitsa mphamvu za konkire, monga kuonjezera mphamvu zake, kuchepetsa ming'alu, kapena kuonjezera permeability. Zitsanzo zina za zowonjezera zomwe zimagwiritsidwa ntchito nthawi zambiri mu konkire yowonongeka ndi monga silika fume, fly ash, kapena zipangizo zina za pozzolanic. Zidazi zimathandizira kukulitsa kulumikizana mkati mwa matrix a konkriti, zomwe zimapangitsa kuti pakhale malo olimba komanso okhazikika. Ponseponse, kuchuluka kwake ndi zida zomwe zimagwiritsidwa ntchito zimatha kusiyanasiyana kutengera momwe konkriti ikugwiritsidwira ntchito komanso kukwanira kofunikira. Komabe, zosakaniza zazikulu za konkire yotha kutha ndi simenti, zophatikizika ndi madzi, ndi zowonjezera zilizonse zofunika zomwe zimawonjezedwa kuti zitheke.

Ngati muli ndi mafunso enieni kapena zosowa zenizeni zokhudzana ndi konkire yowonongeka, mukhoza kufunsa katswiri wopanga.
