Kabedo madongo mi tic
Jam tic maber mi dwoko piny pii (macalu polycarboxylate-based admixtures) nyutho kit piny maber loyo mi dwoko piny pii ma nwangre i soko. Gitiyo ku yubu dispersion layer iwi wi cement particles, ma juku aggregation pa cement particles man eketho concrete bedo maber man tiyo maber. Adwogi mi poko piny eni dwoko piny tic pa pii kende ngo ento medo pek man tego pa got. Ka juporo ku jam piny macon ma jwigo pii piny, jam piny ma tiyo maber akeca mio rwom ma malu mi jwigo pii (ma pol kare 25%-40%) man rwom ma piny ma mitere (ma pol kare 0.1%-0.3% pa wel piny ma jutiyo kudu pi cement), ku adwogi ma nok ikum kabedu.
I tic mi gedo, tic ku piny ma jwigo pii copo medo tego pa got man kero pa got, ma medo kwo pa gedo. Ku lapor, i tic mi gier ot ma malu man lum madongo, piny ma tiyo maber ma jwigo pii weko pii mol maber i thenge mi tego ma lee, ma konyo tic mi gier.
