ʻO nā hale hana hoʻohui ʻāpana nui he ʻelua mau wai e hoʻemi ana i ka ʻano polycarboxylate superplasticizer a me kahi ʻano paʻa slump, akā he aha ka hoʻohana ma waena o lākou?

Ke lawa pono kāu mea paʻa e like me ka sima, hōʻuluʻulu a me ke one, maikaʻi wale ka wai e hoʻoliʻiliʻi ana i kaʻano polycarboxylate superplasticizer. Hoʻohana ʻia kahi ʻano paʻa e hoʻomaʻamaʻa i ka hoʻoliʻiliʻi paʻa. He mana pololei ia i ka paʻa slump paʻa. Inā ʻaʻole kāu mea paʻa. maikaʻi loa, a i ʻole ke maikaʻi ʻole ka hana slump paʻa, a laila pono ʻoe e hoʻohui i ka ʻano paʻa slump, ka lākiō ma waena o ka hoʻoliʻiliʻi wai a me ka mālama ʻana o ka slump he 8: 2 a 7: 3 paha.

Malia paha hiki iā ʻoe ke ʻike i ke kumukūʻai ma waena o ka wai e hoʻoliʻiliʻi nei i ka superplasticizer polycarboxylate a me ka ʻano paʻa slump he mea like ia no kekahi mau hale hana, akā ʻoi aku ka kiʻekiʻe o ke kumukūʻai slump type ma mua o ka hoʻoliʻiliʻi wai. e like me ka hoʻoliʻiliʻi ʻana o ka wai. akā no kekahi mau hale hana, loaʻa nā ʻano like ʻole o ka slump retance type pce e like me ka hoʻoliʻiliʻi wai. ʻO kēia ʻokoʻa e hōʻike ana i ka hana paʻa ke ʻano o ka paʻa slump retention type i ʻoi aku ka hopena slump retention kiʻekiʻe. i kēia manawa, aneane ʻaʻohe hopena hoʻoliʻiliʻi wai.

Ma ke ʻano he conclusition, pono mākou e koho i ka superplasticizer polycarboxylate e like me kā mākou mea paʻa. I kēia ala, nui a koʻikoʻi ka laʻana polycarboxylate superplasticizer ma mua o ke kauoha.
