Mankhwala owopsa amatanthauza mankhwala oopsa kwambiri komanso mankhwala ena oopsa, kuwononga, kuyambika, kuyatsidwa, kutengera mphamvu ya anthu, malo ndi chilengedwe.

Zowonjezera zamadzi zosewerera konkriti zimaphatikizapo mndandanda wa Naphthalene mndandanda, mndandanda wa Melamine ndi othandizira madzi ndi mndandanda wazomwe zimakupangitsani, ndikuwerengera 67%. Mndandanda wa Naphthalene ndi melamine si mankhwala oopsa. Chifukwa chake, simenti SuperPlastiition siili m'gulu la mankhwala owopsa.

Kuphatikizika komwe kungachepetse bwino kuchuluka kwamadzi osakanikirana komwe kutsika kwa konkriti kumakhala kofanana ndi komweko kumatchedwa kuti kuwononga madzi.

Kuchepetsa kwamadzi kwa madzi okwera kwambiri okwera madzi kumatha kupitilira 20%. Zimakhala ndi mndandanda wa mitiriti ya Nahthalene, mndandanda wa Melamine ndi othandizira madzi osokoneza madzi omwe amakula kuchokera kwa iwo, omwe ndi mndandanda waukulu uti, waanthur 67%. Makamaka ku China, ambiri mwa superplaizer ndi a Naphthalene Series Superplasticiters ndi Naphthalene ngati zinthu zazikuluzikulu. Natero Naphthalenes Superplastic itha kugawidwa kukhala zinthu zambiri (na2so4 <3%), zinthu zapakatikati pa 3%) malinga ndi zomwe zili Na3So4 muzogulitsa zake . Zomera zambiri za Naphthalene zimatha kuwongolera zomwe zili Na2SO4 pansipa 3%, ndipo mabizinesi ena otsogola akhoza kuwongolera pansipa 0,4%.
