Concrete plasticizer mmetụta

Usoro mmetụta nke plasticizer bụ isi n'ihi mgbasa ozi nke softener site na cement particles na mgbasa nke ciment irighiri site na ndị na-ebelata mmiri.. Mgbe a na-agbakwunye onye na-ebelata mmiri na ihe ahụ, a ga-ekewa ya na anions macromolecular na cations metal (dị ka Na +, Ca 2+). Macromolecular anions nke na-egosipụta ọrụ elu dị ike na-adaba n'elu akụkụ ciment, na-eme ka akụkụ ciment na-ebubo na-adịghị mma, na akụkụ ciment na-agbasasịkwa n'ihi otu nkwụghachi ụgwọ ahụ.
