2021 ʻAno Maikaʻi o ka Macro Synthetic Reinforced Fiber - Macro Synthetic Fiber Reinforced Concrete – Kehui

He mea hana ka sima me ka ikaika compressive kiʻekiʻe akā ma kahi o ʻumi manawa ka liʻiliʻi o ka ikaika tensile. Eia kekahi, ua ʻike ʻia e kahi ʻano palupalu a ʻaʻole ʻae i ka hoʻoili ʻana i nā kaumaha ma hope o ka haki ʻana. I mea e pale aku ai i ka hāʻule palupalu a hoʻomaikaʻi i nā waiwai mechanical, hiki ke hoʻohui i nā olonā i ka hui sima. Hoʻokumu kēia i ka sima i hoʻoikaika ʻia i ka fiber (FRC) he mea hui sima me ka hoʻoikaika i hoʻopuehu ʻia ma ke ʻano o nā olonā, e laʻa me ke kila, polymer, polypropylene, aniani, kalapona, a me nā mea ʻē aʻe.
ʻO ka sima i hoʻoikaika ʻia me ka fiber he mea hui sima me kahi hoʻoikaika i hoʻopuehu ʻia ma ke ʻano o nā olonā. Hiki ke hoʻokaʻawale ʻia nā olonā polypropylene i nā microfibers a me nā macrofibers ma muli o ko lākou lōʻihi a me ka hana a lākou e hana ai i loko o ka sima.
Hoʻohana pinepine ʻia nā olonā macro synthetic i loko o ka sima kūkulu e like me kahi pani no ka hoʻoikaika ʻana o ka ʻauamo a i ʻole ka lole; ʻaʻole lākou e pani i ke kila kūkulu akā hiki ke hoʻohana ʻia nā olonā macro synthetic e hāʻawi i ka sima me ka mana koʻikoʻi ma hope o ka haki ʻana.

Nā Pōmaikaʻi:
Hoʻoikaika māmā;
Ka mana hoʻomalu māwae kiʻekiʻe;
Hoʻonui ʻia ka lōʻihi;
Ka mana ma hope o ka haki ʻana.
Hoʻohui maʻalahi ʻia i ka hui sima i kēlā me kēia manawa
Nā noi
ʻO ka shotcrete, nā papahana sima, e like me nā kahua, nā alanui, nā alahaka, nā lua eli, a me nā papahana mālama wai.
