ʻOkoʻa ma waena o ka Fine a me ka Coarse Aggregate

Nā Hōʻuluʻulu he mau ʻāpana koʻikoʻi o ka sima. Hana lākou ma ke ʻano he mea inert i loko o ka sima. ʻO ka ʻāwili maikaʻi a me ka ʻāwili nui ʻelua ʻano nui o ka ʻāwili no ka sima. E like me ka inoa e hōʻike nei, ua hoʻokaʻawale ʻia lākou ma muli o ka nui o nā ʻāpana ʻāwili.

He aha ka Aggregate?
ʻO nā ʻāwili nā ʻāpana koʻikoʻi o ka sima e hāʻawi i ke kino i ka sima a hōʻemi pū i ka emi ʻana. Noho nā ʻāwili ma waena o 70 a 80% o ka nui o ka sima. No laila, hiki iā mākou ke ʻōlelo he pono ke ʻike pono kekahi e pili ana i nā ʻāwili i ka hohonu e aʻo hou e pili ana i ka sima.
He aha ka Fine Aggregate??
Ke kānana ʻia ka ʻāwili ma o kahi kānana 4.75 mm, ua kapa ʻia ka ʻāwili ma o ia mea he ʻāwili maikaʻi. Hoʻohana nui ʻia ke one kūlohelohe e like me ka ʻāwili maikaʻi, ua komo pū ka lepo a me ka lepo pālolo ma lalo o kēia māhele.

He aha ka Coarse Aggregate??
Ke kānana ʻia ka ʻāwili ma o kahi kānana 4.75 mm, ua kapa ʻia ka ʻāwili i mālama ʻia he ʻāwili coarse. Aia ka ʻiliʻili, ka pōhaku lepo a me nā pōhaku nui ma lalo o kēia māhele. ʻO ka nui o ka ʻāwili i hoʻohana ʻia e hilinaʻi paha i kekahi mau kūlana. Ma keʻano laulā, hoʻohana ʻia ka ʻāwili nui 40 mm i hoʻohana ʻia no nā ikaika maʻamau a me ka nui 20mm no ka sima ikaika kiʻekiʻe.

ʻOkoʻa ma waena o ka Fine a me ka Coarse Aggregate
He ʻokoʻa nui ko ka ʻākoakoa maikaʻi a me ka ʻākoakoa nui. ʻO nā kumu o nā ʻokoʻa nui ma waena o nā pae hohonu a me nā pae pāpaʻu, ʻo ia ka wehewehe ʻana, ka nui o nā ʻāpana, nā mea hana, nā kumu, ka ʻili, ka hana i loko o ka sima, nā hoʻohana, a pēlā aku.
Ma ka papa ma lalo nei ua hāʻawi ʻia nā ʻokoʻa nui ma waena o ka Fine a me ka coarse aggregate:
