I ka pa apŘ o ke one

Sand manaʻo kanaka lōʻihi ua hoʻohana no ka kūkulu hana, me ka hale ua,ʻaʻole pono kūkulu. He ua hoʻomano hoʻohana i ka maloo kūkuluʻia nā mea huihuina, a i kuai ma ka hale kūʻai a like me ka ke keʻena no ka makaukau o ka lepo pipili wili. ? Ieoaeunoai one ua pili kaumaha ma muli o kona pa apŘ, no kekahi laʻana, kekahi ano i hoʻohana 'ia no ka ho okumu i kekahi masonry ka lepo, ka mea'ē aʻe i ka mea e paka pōhaku puna screed.

Sand - he nonmetallic, me ka moe kolohe hionapāʻili haleʻia. Nō kāu, he hui ana o ka hua liilii ka nui o 0,14-5 mm o, a i hana i ka make ana o maoli pōhaku. He nui na ano o ke one. Ka mea, i wehewehe aku e okoa ka maʻiʻo o ke olonā i (particles) o ka lepo a wale lepo hehee wale.

Keʻoe no ia mau mea, a me ka mea kiekie loa e like ai - keia mea muliwai one. Hawaiiʻino, no ka mea, o ua hapa o ka paakai, mai i ka mea pono e ua holoiʻia. Lua ke one a me ka pōhaku wehewehe aku ma ke alo o ka hua'ōlelo i makemake lepo, a nolaila i ka mea e like ai o ka huahana ma lalo nei. One nui i ka haku mele: pōaka, feldspars, a me impurities i loko o ka palapala o ka silicates, a o ka ia lepo.

No na ano o keia hale mea aia no he mea he mea e like me ka pa apŘ o ke one. Ua Ua oaeuiinoe porosity hiʻohiʻona. No ka laʻana, he papa noho 'inideka o 0,75. Nuʻa ke one e kukulu, kona mea e like ai ua mau manao ma ke alo ma loko o ka lepo. Poe hana hale i makemake e hana me ka hanana ka pololei - River huahana. Ua loaʻa i ka pa apŘ o 1,3 Halau. Per cubic mika. I ka pa apŘ o ke one, a me ka lepo maʻiʻo ka ua ma luna o 1.8 m. Ma ka ia ka leo.

Kēia mea o ke kumu o na makahiki o ka lepo pipili, a pōhaku puna mele. Ua Ua loa koi no ka hoomoe ana i alanui, me-puhi aniani 'atikala a me ka mahiai.

Ma ka hana o ka kahua nui i ka manaʻo o ka pa apŘ, i mea o ka lākiō o ka ahakanaka o ke one a hiki i ka buke, ka mea, i ke ana o ka mokuna: g. / Cm3, kg / m3. Natural bulk pa apŘ o ke one o 1300-1500 kg / m3.

Bulk? Ieoaeunoai kumuhana, keia aka mea ee iaaanu aey a me ka hilinaʻi nui ma luna o ka degere o ka compaction. Ma ka hoʻomaopopo aku i ka hookahi dala o ka huahana i he okoa dala. Nuʻa one invariably e kaukaʻi ma humidity a me kekahi o kona likeʻole aloha ia bulk nuʻa. At kiekie ona mau mānoanoa ko uhi ma kekahi ahu iho la ka wai, a pela i ke dala o ke one, piʻi pū dramatically. I bulk pa apŘ o ke one o ke oscillation humidity i loko, no ka wā helu ana i ka laʻau heluna o ke one a hiki i ka makemake noi. Inā 'oe e ole lawe i loko, no keia ololi,ʻaʻole ka lepo e i ka mea e pono ai ka maluhia palena pau a me ka nohona ma' enekinia, mea i manao ai, e substandard.

Anoʻano nui hoʻohana alluvial one, kona extract Ua puni hoʻi - holoi one quarry. Kēia Ua hana like penei: holoi he nui ka leo o ka wai mau mea ka lepo a me ka lepo.

hana ana i ke one nuʻa hilinaʻi nui ma luna o ka mōhaiʻai 'ole. No ka laʻana, ka mea kiʻekiʻe uku o ka pololei hoike o ka mea e like hapa o kona anuanu, loa ikaika a me ke anu-hoʻopale mānoanoa. 'O kēia ka mea me ke kaʻi lau waiwai kiʻekiʻe mea paʻa mau i ka hana i loko o permafrost ana. He mea ke kumu o ke kiʻekiʻe-ikaika pōhaku puna, me ka maikai hardiness.

Nuʻa o ka pōaka one hiki mahuahua i loko o ka moe kolohe ana wehewehe aku ma ka 'inideka o 1500 kg / m3, akā, i ka 1700 kg / m3. Ua Ua wehewehe aku ma ka mea maikai loa hygienic ano, a ua holoi iho la, a calcined maloo kūlohelohe mea. Wā hoʻohana 'ia i loko o kūkulu kaulike kiʻekiʻe hygienic ano noho. I ka pa apŘ o pōaka one - he mea nui aiao i ka ia i loko o ka mooolelo i kūkulu.
