Monga kusakaniza konkriti, wochepetsera madzi amatenga gawo lofunikira pakuwongolera konkriti. Madzi kuchepetsa wothandizila ndi admixture amene angathe kuchepetsa kwambiri kusakaniza kumwa madzi pamene kusunga mlingo ntchito simenti phala, matope ndi konkire osasintha. Impermeability kapena kuchepetsa simenti mlingo. Chitsanzochi chimapereka njira yogwiritsira ntchito zinyalalaPET pulasitikikupanga zochepetsera madzi, zimatha kubweza zinyalalaPET pulasitiki, kuchepetsa kuipitsa, kuchepetsa mtengo wopangira wochepetsera madzi.
Zinthu za polyester zochokera ku ziweto siziwonongeka, ndipo zimakhala ndi ubwino wokhala ndi zowonongeka, kuthetsa kufunika kogwiritsanso ntchito terephthalic acid ndi ethylene glycol polima. Komabe, luso processing ndi yobwezeretsanso waPET zipangizoakufunikabe kutukulidwa ndi kukonzedwanso. Polyester ndiye chinthu chachikulu pansalu zosalukidwa zosalukidwa, zomwe zimatha kugwiritsidwa ntchito pa 260 ° C kwa nthawi yayitali. Nsalu zopindidwa komanso zotentha zosalukidwa kuchokera ku zinyalala za PET zimatha kuchepetsa mtengo wopangira mabizinesi. Pogwiritsa ntchito mokwanira makhalidwe a recycledpoliyesitala zipangizo, Mphamvu za poliyesitala zopindidwa ndi nsalu zosalukidwa zotentha zimapititsidwanso bwino kudzera pakuwongolera njira.
