ʻO nā mea hoʻohui paʻa, i ʻōlelo ʻia he admixtures no ka pōkole, e pili ana i nā mea i hoʻohui ʻia ma mua a i ʻole i ka wā o ka hui ʻana i ke kaʻa no ka hoʻomaikaʻi ʻana i nā waiwai o ke kaila hou a/a i ʻole ka paʻa paʻa. ʻO nā hiʻohiʻona o ka hoʻohui ʻana i nā ʻāpana he nui nā ʻano a me
liʻiliʻi liʻiliʻi, kahi mea koʻikoʻi i ka hoʻololi ʻana. Me ka hoʻomohala lohi o ka ʻoihana kūkulu, ke hoʻomau nei ka koi ʻana i ka ʻenehana i nā hana ʻenekinia, a ma ka manawa like, aia nā koi kiʻekiʻe no ka hana a me ka maikaʻi o ka ʻoihana. Ma kēia pōʻaiapili, ma ke ʻano he mea ʻenekinia koʻikoʻi hiki ke hoʻomaikaʻi nui i ka hana o ke kaʻa, ua lilo nā admixtures paʻa i mea pono ʻole i ka ʻelima o ka ʻenehana hou ma waho o ka sima, ke one, ka pōhaku a me ka wai.
ʻO ka mea hoʻohaʻahaʻa wai kiʻekiʻe e hoʻokaʻawale ʻia i ʻekolu mau ʻāpana: ʻo ka mea hoʻohaʻahaʻa wai maʻamau, ka mea hoʻohaʻahaʻa wai kiʻekiʻe a me ka mea hoʻohaʻahaʻa wai kiʻekiʻe. ʻO ka hoʻomohala ʻana o nā superplasticizers ua hele i ʻekolu mau pae: ʻo ka hanauna mua o nā superplasticizer maʻamau i hōʻike ʻia elāʻau calcium, ka lua o ka hanauna o nā superplasticizer i hōʻike ʻia enaphthalenemoʻo, a ʻo ke kolu o ka hanauna o nā superplasticizers i hōʻike ʻia epolycarboxylate superplasticizermoʻo. Ka hana ʻana o ke kahua superplasticizer kiʻekiʻe.Polycarboxylate superplasticizerloaʻa nā mea maikaʻi o ka haʻahaʻa haʻahaʻa a me ka hoʻohaʻahaʻa wai kiʻekiʻe, a hiki ke hoʻohana ʻia no ka hoʻokumu ʻana i ka ikaika kiʻekiʻe, ultra-high-strength, high-durability and super-fluid concrete; ʻAʻohe wai ʻōpala i ke kaʻina hana, ʻōpala kinoea, hoʻokuʻu koena ʻōpala a me nā mea ʻē aʻe. He ʻōmaʻomaʻo a ʻoluʻolu hoʻi i ka wai hoʻohaʻahaʻa wai hana kiʻekiʻe, a loaʻa iā ia nā pōmaikaʻi i ka mālama ʻana i ke kaiapuni a me ka pono. Me ka hoʻonui ʻana i ka mana hana a me ka hoʻomaikaʻi ʻana i ka permeability, ua lilo nā polycarboxylate superplasticizers i nā ʻano nui o nā superplasticizers i hana ʻia a pau i koʻu ʻāina.
Ma ka pōʻaiapili o ka "ulu paʻa" i manaʻo ʻia e hoʻomau i ka wela, ʻo ka piʻi ʻana o ka noi no ke koʻikoʻi i lawe ʻia e ka piʻi ʻana o ka hoʻolālā ʻana i nā papahana ʻenekinia nui a me ka holomua o ka papa hana e hoʻonui ai i ka noi no nā admixtures paʻa ma ka manawa like. Eia kekahi, e like me nā hōʻike hana aupuni i hoʻopuka ʻia e nā panalāʻau like ʻole, ʻo ke kūkulu ʻana i nā ʻoihana e like me ka lawe ʻana a me nā papahana mālama wai no ka hapa nui o nā papahana nui, a ʻo nā papahana i ʻōlelo ʻia ma luna nei he kiʻekiʻe o nā koi hana no ka ʻuala, a me ka wai kiʻekiʻe. koi ʻia nā mea hoʻemi e hoʻokō i nā koi o ke kaʻa. Ke hoʻohālikelike ʻia me nā ʻano mea hoʻohui ʻē aʻe, pono ka hana ʻana i ka pumping a me ka hōʻemi ʻana i ka vibration a me nā pono ʻole o ka vibration o nā pāhana paʻa kūikawā. No laila, ʻo ka hapa o ka noi no nā mea hoʻohaʻahaʻa wai kiʻekiʻe e hiki ke hoʻokō i nā hana ʻenehana "tailor-made" e manaʻo ʻia e hoʻonui hou aʻe.
ʻO ka ʻoihana waiwai ʻo Jufu Chemical Company ʻē aʻe ma mua o ka ʻoihana nui o nā superplasticizers e hōʻike ana i ka loiloi huahana kumu i ʻokoʻa loa mai kāna mau mea hoʻokūkū. I ka wā e hiki mai ana, hiki iā ia ke hoʻohālikelike i ka kūleʻa o ka ʻoihana superplasticizer, a ʻoi aku ka kiʻekiʻe o ke kaupaku o ka mākeke ma mua o nā superplasticizers.
