A ttha ngaimi ti-tlawmtertu cawhmi: A hringmi saknak caah concrete riantuan ning tthanchoter
A Biapimi Hmannak Hmun
A ttha ngaimi ti-tlawmternak cawhmi (polycarboxylate-based cawhmi tibantuk) nih market ah hmuh khawhmi ti-tlawmternak thilri phun ttha bik a aiawh. Cement tlawmpal hna cung ah tthencheunak tthen sernak in rian an ttuan, cement tlawmpal hna i fonhnak kha an kham i cu nih cun concrete a luan khawhnak le riantuan khawhnak a tthanchoter. Hi tthencheunak nih ti hmannak a zorter lawng si loin concrete a ritmi le a fekmi zong a karhter. Hlanlio ti-tlawmternak cawhmi he tahchunh ahcun, tthatnak a sangmi phun nih ti-tlawmternak rate sang deuh (a tlangpi in 25%-40%) le a tlawm deuhmi zat (a tlangpi in cement thilri dihlak 0.1%-0.3%) an pek, pawngkam hnahnawhnak tlawm deuh he.
Inn saknak riantuannak ah, ti a zortermi cawhmi hmannak nih concrete a tthawnnak le ti a tei khawhnak kha a tthanchoter khawh, inn saknak hna an riantuan caan a sauter khawh. Tahchunhnak ah, inn sangpi le tlanglawng lam ngan pipi saknak ah, ttha tein ti a zortermi cawhmi nih a tthawngmi herhbaunak tangah concrete a ttha tein a luang khawhnak hnga a bawmh, saknak riantuannak a bawmh. Cun, ti a zortermi cawhmi nih concrete chung i thi chuah le tthencheunak a zorter khawh, a tlukruannak le aa khatmi a tthanchoter.
A hringmi saknak lei ah, ti zorternak cawhmi thilri hna i pawngkam sining hna cu a hleiin a biapi. A ttha ngaimi ti zorternak cawhmi hmannak nih cement hmannak a zorter khawh, cucaah carbon chuahmi a zorter khawh. Cun, hi cawhmi hna nih hin concrete a fekmi a tthanchoter khawh, zohkhenhnak man le inn saknak caah thilri hmannak a zorter khawh. A ttha ngaimi ti zorternak cawhmi tampi nih ramkip pawngkam zohkhenhnak hnatlaknak an hmuh ve, a hmunmi tthanchonak tinhmi he aa tlak.
Inn saknak thiamnak a karh pengmi he, ti zorternak cawhmi hmannak zong a karh chin lengmang. Tahchunhnak ah, riantuannak sang a ngeimi concrete (HPC) le amah tein aa fekmi concrete (SCC) ah, ti a zortermi cawhmi hna cu a tthawngmi le a fekmi thil sining tangah concrete amah tein aa tluk khawhnak ding caah a biapi mi thilri an si. Cun, ti a zortermi cawhmi hna cu a dang cawhmi hna (retarders le air-entraining agents tibantuk) he fonh in concrete sining hna kha ttha deuh in hman khawh a si.
