Makhalidwe a muyezo wamadzi wochepetsa mphamvu umakhudza mwachindunji magwiridwe antchito a syrete. Pansi pa ma connewte yofananira, kuchuluka kwa ma scerete ndi mankhwala osokoneza bongo omwe ali pafupifupi 35% apamwamba kuposa a konkriti popanda wothandizira madzi. Chifukwa chake, ming'alu ya konkriti imapezekanso. Nayi chifukwa:
1. Kuchepetsa kwamadzi kumadalira kwambiri zida zokometsera ndi kusakaniza kuchuluka.
Kuchepetsa kwamadzi kwa konkriti ndi tanthauzo labwino kwambiri, koma nthawi zambiri kumayambitsa kusamvana. Nthawi zambiri, anthu nthawi zonse amagwiritsa ntchito madzi ochepetsa madzi kuti afotokozere madzi kuchepetsa zotsatira za malonda.
Pamlingo wotsika, potenga mankhwala polycaxtlate madzi, mwachitsanzo, zatsimikiziridwa kuti zatsimikiziridwa kuti ndi kuchuluka kwake kwamiyala ina ndikokulirapo kuposa mitundu ina ya othandizira madzi, ndipo imakhala ndi mphamvu yabwino. Komabe, ziyenera kudziwitsidwa kuti poyerekeza ndi othandizira ena, kuchepetsa madzi polycaxtote madzi ochepetsa madzi amakhudzidwa kwambiri ndi mikhalidwe yoyeserera.
Zina mwazinthu zomwe zimapangitsa kuti pulasitiki mphamvu ya polycattoteplet nthomba, mchenga wamchenga ndi tinthu tating'onoting'ono tomwe timalumikizananso ndi konkriti zimakhudzanso kwambiri. Poyerekeza ndi mitundu ina ya madzi okwera kwambiri monga mndandanda wa a Naphtalene, zomwe zimapangitsa kuti ma polycakhotet madzi ochepetseke azikhudzidwa kwambiri ndi matope omwe ali ndi vuto lalikulu.
2. Kuchepetsa madzi kumadalira kwambiri mlingo wa wothandizira madzi.
Mwambiri, chifukwa kuchuluka kwa mankhwalawo kumawonjezeka, kuthira kwamadzi kumawonjezekanso, makamaka kwa ma acid a acid-ogwiritsa ntchito madzi, mlingo umakhudzanso mphamvu yamadzi.
Komabe, pali zosiyana pakugwiritsa ntchito. Ndiye kuti, pambuyo pa mlingo wina wafikiridwa, mphamvu yochepetsera madzi "imachepa" monga momwe mankhwala akuwonjezeka. Izi ndichifukwa nthawi imeneyi osakaniza konkriti amawumitsidwa, konkriti imadwala magazi akuluakulu, ndipo malamulo owonda sangathenso kufotokoza zakumwa zake.
3. Kuchita kwa osakaniza kokonzekera kumathandiza kwambiri kugwiritsa ntchito madzi.
Zizindikiro za magwiridwe antchito osakanikirana nthawi zambiri zimawonetsedwa kawirikawiri monga kusungidwa kwamadzi, kolumikizana, ndi madzi. Konkrete wokonzedweratu pogwiritsa ntchito polycabobotric acid - superpucciresers osakhazikika nthawi zonse samakwaniritsa zofunikira za kugwiritsidwa ntchito. Kuchita bwino kwa osakaniza konkriti kumakhudzidwa kwambiri ndi kumwa madzi, ndipo mavuto ena nthawi zambiri amachitika.
