Jami ma ki rubu ma dwoko piny pii ma tiyo maber: Medo tic pa konkrit pi gedo ma pe balo pii
Kabedo ma pire tek me tic kwede
Jami ma ki rubu ma tiyo maber me dwoko piny pii (ma calo polycarboxylate-based admixtures) nyutu jami ma ki tiyo kwede me dwoko piny pii ma tye i cuk. Gi tio kun gi yubu dul ma nyaa i kom jami ma ki lwongo ni cement, ma gengo jami ma ki lwongo ni cement me bedo kacel ki medo rwom me mol ki tic pa cement. Adwogi me poko ne ni pe dwoko piny tic ki pii keken ento bene medo pek pa got ki teko pa got. Ka kiporo ki jami macon ma ki rubu me dwoko piny pii, jami ma tiyo maber ni miiyo rwom me dwoko piny pii ma malo (pol kare 25%-40%) ki rwom ma lapiny ma mite (pol kare 0.1%-0.3% me wel jami ma ki yubu ki cement), ki adwogi manok i kom kabedo.
