I kēia manawa, hoʻohana ʻiapolycarboxylate superplasticizerHe mea maʻamau nā mea hoʻemi wai i ke kūkulu ʻana, no ka mea hiki i kā lākou huahana ke hoʻomaikaʻi i ka ikaika o ka hale a me ka maikaʻi ʻenehana.He ʻōmaʻomaʻo kēia huahana, ʻaʻole hiki ke puhi ʻia, ʻaʻole pahū, a hiki ke lawe pono ʻia e ke kaʻaahi a me ke kaʻa.Ke piʻi ka dosage o ka mea hoʻohaʻahaʻa wai i ka 0.9% ~ 1.1%, hiki ke mālama ʻia ka slump o ke kaila me ka ratio sima wai o 0.12-0.16 a me kahi one one o 38% hiki ke mālama ʻia ma luna o 250mm no 2 mau hola, hiki i ka hoʻonui ke hiki i 600mm, ʻo ka manawa hoʻonohonoho hope i loko o 24 mau hola, a ʻaʻohe mea hoʻokaʻawale.ʻO ka ikaika compressive i nā lā 90 ʻoi aku ma luna o 180MPa. No laila he mea koʻikoʻi loa ia i ke kūkulu ʻana, a ʻo ka mea aʻe e hoʻolauna i kāna mau pono.
1. He haʻahaʻa loa ka ʻike alkali a me ka chloride ion, a me ka hoʻohui ʻana opolycarboxylate superplasticizerʻAʻole hiki i ka waiʻona makuahine ke hoʻopōʻino i ka ʻinoʻino i nā kaola kila a ʻaʻohe hopena ʻino i ke kaʻa.I ka manawa like, ʻaʻole paʻakai ka huahana a i ʻole crystallize i nā kau wela haʻahaʻa, e maʻalahi ka hoʻohana.
2. He mea maikaʻi ia no ka hana ʻana o nā hui ʻana, hoʻemi i ke koko, hoʻomaikaʻi i ka maikaʻi o ka hiʻohiʻona a me ka lōʻihi o ka paʻa paʻa paʻa, a kūpono loa no ka hoʻohana ʻana i nā papahana paʻa paʻa.
3. ʻO ke kaʻa i hoʻomākaukau ʻia mepolycarboxylate superplasticizerʻAʻole e hōʻike ka waiʻona makuahine i ka wehe ʻana a i ʻole ke kahe ʻana o ke koko ma lalo o nā kūlana haʻahaʻa kiʻekiʻe, a ua ʻano like ke kala o ka ʻili.Ke hoʻohana ʻia no ka hoʻomākaukau ʻana i ke kiʻekiʻe kiʻekiʻe, ʻoi aku ka maikaʻi o ka hana ʻana, ka hui ʻana maikaʻi, a maʻalahi ka hui ʻana.
No laila pono loa nā mea hoʻemi wai polycarboxylate no ke kūkulu ʻana.Ke hoʻohana ʻia, hoʻohui pinepine ʻia lākou i ka like, ʻaʻole ia e hoʻoikaika i ka papahana akā e hōʻemi ana i nā pōʻino like ʻole.Ma ka hoʻomaopopo wale ʻana i nā waiwai waiwai a me nā pōmaikaʻi hiki iā mākou ke hoʻohana pono iā lākou i ka pae hope.Polycarboxylate superplasticizerʻO ka mea hoʻohaʻahaʻa wai he mea hoʻohaʻahaʻa wai hana kiʻekiʻe a me ka dispersant sima i hoʻohana ʻia i ka hoʻohana ʻana i ka sima.Hoʻohana ʻia i nā papahana e like me nā alaloa, nā alahaka, nā dams, tunnels, a me nā hale kiʻekiʻe.
