   • Superplasticizers: Superplasticizers, nke a makwaara dị ka ndị na-ebelata mmiri dị elu (HRWR), bụ ndị na-ebelata mmiri dị irè nke ukwuu nke na-achụsa irighiri ciment nke ọma karịa ndị na-emepụta ihe.Ha na-arụ ọrụ site n'ịgbanye n'elu akụkụ ciment na ịmepụta ihe nkiri dị mkpa, nke na-emepụta ike na-asọ oyi n'etiti ihe ndị ahụ, si otú a na-ebelata mmiri na-ciment ruru na-enweghị imebi ọrụ.
2. Mbelata mmiri:
   • Plasticizers: Plasticizers na-ebelata ọdịnaya mmiri nke ngwakọta ihe site na 5% ruo 15% ka ha na-arụ ọrụ.
   • Superplasticizers: Superplasticizers nwere ike nweta ọkwa dị elu nke mbelata mmiri, nke na-adịkarị n'ogo nke 20% ruo 40%, na-enye ohere maka nkwalite dị ịrịba ama na ike siri ike, ịdịte aka na arụmọrụ.
3. Usoro onunu ogwu:
   • Plasticizers: A na-ejikarị plastik eme ihe na obere doses ma e jiri ya tụnyere superplasticizers n'ihi ike ha na-ebelata mmiri na-agafeghị oke.
   • Superplasticizers: Superplasticizers chọrọ nnukwu doses iji nweta mbelata mmiri a chọrọ ma na-ejikarị ya na mgbakwunye ndị ọzọ iji kwalite arụmọrụ.
4. Mmetụta na ịrụ ọrụ:
   • Plasticizers: Plasticizers na-ebute ụzọ na-eme ka arụ ọrụ na ịrụ ọrụ nke ngwakọta ihe, na-eme ka ọ dị mfe idowe, kọmpat na imecha.
   • Superplasticizers: Superplasticizers na-enye uru ndị yiri ya na ndị na-emepụta ihe mana ha nwere ike nweta ọkwa dị elu nke ịrụ ọrụ na ịgba ọsọ, na-enye ohere maka mmepụta nke nnukwu mmiri mmiri na ngwakọta ihe na-eme ka ọ dị elu.
5. Ngwa:
   • Plasticizers: Plasticizers na-ejikarị na a dịgasị iche iche nke ihe ngwa ebe a chọrọ mma workability na mfe njikwa, dị ka njikere mix, precast concrete na shotcrete.
   • Superplasticizers: A na-ejikarị superplasticizers eme ihe na ngwakọta kọmpụta na-arụ ọrụ dị elu ebe a na-achọ ike dị elu, ịdịte aka na njiri na-asọpụta, dị ka n'ime ụlọ ndị dị elu, àkwà mmiri, na ọrụ akụrụngwa.

Na nchịkọta, ebe a na-eji ma plasticizers na superplasticizers iji melite arụmọrụ na ịrụ ọrụ nke ngwakọta ihe, superplasticizers na-enye ike mbelata mmiri ka ukwuu ma na-ejikarị eme ihe na ngwa ọrụ dị elu nke na-arụ ọrụ dị elu ebe ike, ịdịte aka na nkwụsị dị oke mkpa.
