1. Kiʻekiʻe Wai-Hoemi Wai: Loaʻa i ka 40% hoemi wai, ka hoʻohaʻahaʻa nui ʻana i ka hoʻohana ʻana i ka wai no kēlā me kēia ʻāpana o ka nui o ke koʻikoʻi a hāʻawi i kahi kumu paʻa no ka hana ʻana i ka ikaika kiʻekiʻe a me ka ultra-high-strength concrete. (C60 a ma luna).

2. Paʻa Slump maikaʻi loa: Hoʻoponopono maikaʻi ka ʻenehana hoʻokuʻu lohi lohi i ka poho slump, mālama maikaʻi workability a pumpability no 1-2 hola. Hoʻokō kēia i nā koi o ka halihali lōʻihi a me ke kūkulu ʻana i nā kau wela kiʻekiʻe.

3. Haʻahaʻa haʻahaʻa, hana kiʻekiʻe: Hoʻohālikelike ʻia me nā mea hoʻemi wai maʻamau, pono ia i ka dosage haʻahaʻa (maʻamau 0.15%-0.3% ma ke kaumaha o na mea sima) ʻoiai e hāʻawi ana i ka hana nui, hāʻawi ʻoi aku ka maikaʻi o ka hoʻokele waiwai a me ke kaiapuni.

4.  Hiki ke hoʻololi: Hoʻohālikelike me nā ʻano pahu sima like ʻole a me nā mea hoʻohui mineral (e.g., lehu lele, pauda mineral, uahu silika), e hoʻoponopono maikaʻi i nā pilikia maʻamau e like me ke kahe koko a me ka hoʻokaʻawale ʻana i loko o ke koneki.

5.  ʻOmaomao a me ka Eco-Friendly: Mai nā mea ʻino e like me formaldehyde a me nā nitrite i ka wā o ka hana ʻana, mea ino ole i kanaka, pili kaiapuni, a kūpono i nā hale ʻōmaʻomaʻo a me nā koi hoʻomohala hoʻomau.

6. Hoʻonui i ka ikaika nui: Loaʻa i kahi 10%-15% hoemi i ka hoohana ana i ka sima no ka ikaika like, a i ʻole e hoʻonui nui i ka ikaika paʻa i nā makahiki āpau me ka maʻiʻo sima like.

7. Hoʻonui ʻia ka Paʻa Paʻa: Hoʻohaʻahaʻa maikaʻi i ka coefficient diffusion chloride, hoemi i ka emi a me ka kolo, a hoʻomaikaʻi maikaʻi loa i ka impermeability, kūʻai hoʻoheheʻe, a me ka pale kalapona, hoʻonui i ke ola lawelawe hale.

ʻO ka Superplasticizer ma muli o ka Polycarboxylate: Nā ʻāpana mea hoʻopunipuni

Nānā a me ke kino

Hele mai kēia superplasticizer ma ke ʻano he wai māmā-melemele. Hoʻohui maikaʻi ʻia me ka wai a noho paʻa ma lalo o nā pilikia o ka waiho ʻana.

Mea Paʻa

Aia ka mea 20% i 40% solids by weight. Kākoʻo kēia ʻano i ka noi kūpono e pili ana i kāu hoʻonohonoho hui a me nā pono hana.

mānoanoa

E hāʻule ana kona mānoanoa ma waena 1.05 g/cm elima a 1.10 g/cm four at area temperature. This makes handling and determining straightforward on site.

Waiwai pH

The pH level is generally 5 i 7 , kahi kokoke i ke kūʻokoʻa. This aids secure steel support from corrosion and maintains the mix chemistry well balanced.

Chloride Content

Chloride ions are kept below 0.1%. Reduced chloride degrees indicate more secure usage in enhanced and prestressed concrete.

Water Decrease Price

It provides a high water decrease of 25% i 40%. Less water indicates stronger, ʻoi aku ka paʻa paʻa me ka nalowale ʻole o ka hana.

Downturn Retention

Concrete mixed with this admixture holds its downturn for 60 i 90 minutes or much more. This offers you sufficient time for transport and placement, also in hot weather.

Compressive Toughness Gain

Very early toughness increases quick– commonly 140% i 180% of control mix toughness at 1 lā. Ma ka 28 lā, stamina can reach 120% i 130% of common mixes.

Hoʻolikelike

Hana maikaʻi ia me nā sima he nui, ʻO ke kūlanakauhale Rose, huikau, a me nā ʻano pale pale sulfate. E holo mau i kahi hoʻāʻo i hoʻonohonoho ʻia e hōʻoia i ka pono me kāu mau kikoʻī kikoʻī.

Hoʻolāʻau Dose

ʻO ka maʻa mau 0.1% i 0.3% ma ke kaumaha o ka sima. Hoʻoponopono ma muli o ke kaʻa ʻana i makemake ʻia, kau manawa, a me nā pilikia ambient.

Wahi mālama a me ka lawelawe ʻana

E kūʻai i kahi anuanu, wahi maloʻo mamao loa i ka lā pololei. E mālama i nā pahu i hoʻopaʻa ʻia ke hoʻohana ʻole ʻia. ʻO ke ola lawelawe 6 to twelve month if stored properly.

Noi o ka Polycarboxylate-Based Superplasticizers in Concrete

Hana Maʻalahi ʻia ka Paʻa Kiʻekiʻe

Hoʻohana nui ʻia nā superplasticizers e pili ana i ka polycarboxylate i loko o ka hana kontemporary. ʻO kēia mau mea hoʻohui kemika e kōkua i ka hōʻemi ʻana i ka nui o ka wai e pono ai i loko o kahi hui ʻoiai e mālama maʻalahi i ka ʻāpana a me ke ʻano.. ʻOi aku ka ikaika o ka wai liʻiliʻi, ʻoi aku ka paʻa paʻa.

Hoʻohana ka poʻe aelike hale i kēia mau superplasticizers i ka wā e pono ai lākou i ke kaila ikaika kiʻekiʻe no nā hale kiʻekiʻe, alahaka, a i ʻole nā ​​tunnels. ʻO ka admixture e hiki ai iā lākou ke ninini i ke koneki i loko o nā lumi liʻiliʻi me ka ʻole o ka nalowale ʻana. Kōkua ia i ka pale ʻana i ka honeycombing a i ʻole nā ​​wahi nāwaliwali e hiki mai ana ke paʻa pū kekahi.

ʻOi aku ka maikaʻi o ka hana me ka wai ʻole

ʻO kahi pōmaikaʻi nui ka hoʻomaikaʻi ʻana i ka hana. Hiki i nā mea hana ke hoʻoneʻe a hoʻopau i ke kaʻa me ka liʻiliʻi o ka hana. He mea nui kēia ma nā wahi hana i kaupalena ʻia ka manawa. Mālama ka superplasticizer i ka wai hui no ka lōʻihi, no laila ʻaʻohe wikiwiki i ke kau ʻana.

ʻAʻole like me nā ʻano plasticizer kahiko, ʻAʻole hiki i nā mana polycarboxylate ke hoʻohaʻahaʻa wikiwiki. ʻO ia ke ʻano o ka hana ʻana o ke koʻi mai ka hale hoʻouluulu a hiki i ka pūnaewele. Hoʻohaʻahaʻa kēia kūlike i ka ʻōpala a hoʻoponopono hou.

Hoʻomau a maikaʻi

ʻO ka hoʻohana ʻana i ka wai liʻiliʻi e hōʻemi i ka hoʻohana ʻana i ka sima i nā hui he nui. Hoʻemi kēia i ka hopena kalapona o kēlā me kēia pūʻulu. Hoʻokō koke ka poʻe ʻaelike i nā koi o ka hoʻolālā pili i ke kaiapuni i ka wā e mālama ai i ke kālā.

Hana maikaʻi kēia mau mea hoʻohui me nā huahana ʻē aʻe e like me ka lehu lele a i ʻole ka slag. Kākoʻo lākou i nā ʻano hana mau me ka hōʻeha ʻole i ka hana. ʻOiai i ka mahana a i ʻole ke anuanu, Hāʻawi nā polycarboxylate superplasticizers i nā hopena hilinaʻi.

Nā hana e koi ana i ka pololei– e like me nā hiʻohiʻona precast a i ʻole nā ​​hale ʻili lahilahi– pomaikai loa. Hoʻopili maikaʻi ʻia ke kaʻa ʻana a puni ka rebar paʻa a hoʻopiha i kēlā me kēia kihi. Puka maʻemaʻe nā ʻili ʻili, me nā pilikia liʻiliʻi.

holookoa, Hāʻawi nā superplasticizers e pili ana i ka polycarboxylate i nā ʻaelike e hoʻoponopono, hoʻoikaika kino, a me ka hana ʻana i hoʻokahi mea hoʻohui pololei. Ua lilo lākou i mea koho maʻamau no ke koki maikaʻi ma ka honua holoʻokoʻa.

ʻO ka moʻolelo o ka hui

ʻO mākou ke alakaʻi o ka honua i nā ʻenehana māmā a me nā hoʻonā ʻenehana i hana ʻia. ʻIke ʻia ma ka honua holoʻokoʻa no kāna kūpaʻa i ka noiʻi, mea hou, a me ka ʻike noiʻi, ke hāʻawi nei mākou i nā hoʻonā ʻenehana i hana ʻia mai ka makahiki 2012.

Hiki iā mākou ke hāʻawi aku i ka hoʻohui ʻana i nā mea hoʻohui kiʻekiʻe kiʻekiʻe a me nā huahana pili i ka foam concrete a puni ka honua.

He keʻena ʻenehana ʻoihana a me ka ʻoihana kiaʻi maikaʻi ka hui, he hale hana i hoolako pono ia, a hoʻolako ʻia me nā lako hoʻāʻo kiʻekiʻe a me ke kikowaena lawelawe mea kūʻai aku ma hope o ke kūʻai aku.

He aha ka polycarboxylate-based superplasticizer?

ʻO ia kahi mea hoʻohui hoʻohui kiʻekiʻe. Hoʻemi ia i ka nui o ka wai e pono ai i loko o ka hui ʻana. Kōkua kēia i ka hoʻoikaika ʻana, ʻoi aku ka ʻoi aku o ka hana me ka hoʻohui ʻole i ka wai.

Pehea e hoʻomaikaʻi ai i ke koʻo?

ʻO ka superplasticizer e hoʻopuehu like i nā ʻāpana sima. Hoʻonui kēia i ka kahe ʻana a maʻalahi ka hui ʻana. I ka manawa like, mālama ia i ka wai haʻahaʻa. ʻO ka wai haʻahaʻa ʻo ia ka ikaika kiʻekiʻe a ʻoi aku ka lōʻihi o ka manawa.

Hiki ke hoʻohana ʻia me nā mea hoʻohui ʻē aʻe?

ʻAe, akā pono ʻoe e hoʻāʻo mua i ka hoʻohālikelike. Hiki i kekahi hui ke hoʻopili i ka hana a i ʻole ka hoʻonohonoho manawa. E holo mau i nā hoʻokolohua liʻiliʻi ma mua o ka hoʻohana piha ʻana ma ka pūnaewele.

He aha ka dosage kūpono e hoʻohana ai?

Hoʻopili ʻia ka dosage i ke ʻano sima, hoʻolālā hui, a me nā hopena i makemake ʻia. Nā uku maʻamau mai 0.1% i 0.5% ma ke kaumaha o ka sima. E hahai i nā ʻōlelo a ka mea hana. Hoʻoponopono wale ma hope o ka hoʻāʻo ʻana.

Hoʻopilikia ka mahana i kāna hana?

ʻAe. Hiki i ke anuanu ke hoʻolohi i kona hopena. Hiki i ka wā wela ke hoʻopōkole i ka manawa hana. Ma nā kūlana koʻikoʻi, pono paha ʻoe e hoʻoponopono i ka nui a i ʻole e hoʻohui i nā mea kemika ʻē aʻe e like me nā retarder a i ʻole nā ​​​​mea hoʻokele. E nānā mau i nā mea hou a paʻakikī i ka wā e loli ai ka mahana.
