The arambe achirema nejecha

Sand vanhu kare pakuvaka zvinangwa, pasina imwe imba haisi chaizvo kuvaka. Ari zvinowanzoshandiswa yakaoma pakuvaka wemisanganiswa, izvo inotengeswa muzvitoro kana somunhu chezvinonhuwira kuti gadziriro esimende dhaka. Construction jecha rinoshandiswa zvichienderana ayo arambe achirema Somuenzaniso, mamwe marudzi inoshandiswa kuumba munhu masonry nedhaka, mumwe kuti pave kongiri screed.

Sand - mumwe nonmetallic, pamwe unzenza unaku chivakwa zvinhu. Kazhinji, musanganiswa zviyo kukura 0,14-5 neMM, iyo yakaumbwa mumakore kuparadzwa dzinongoitika namatombo. Pane zvakawanda siyana jecha. Vari ne akasiyana zviri zvomucheka tudonhwe nevhu kana kungoti guruva zvinhu.

Chaiyoiyo wavo, uye chemhando yepamusoro - izvi remurwizi. Marine ainyanyisa, sezvo yatova chikamu munyu, izvo zvinofanira kucheneswa. Gomba jecha uye dombo inozivikanwa nokuvapo ivhu pamusingadi, uye nokudaro kunaka chigadzirwa pazasi. Sand Kazhinji ane nziyo: Goldstone, feldspars, netsvina ari muchimiro silicates uye zvakafanana ivhu.

Nokuti zvinoitwa ichi chivako zvinhu pane zvakadai chinhu sezvo arambe achirema nejecha. Zvinofungidzirwa porosity reshiyo. Somuenzaniso, giredhi wakanaka nhaka indekisi pamusoro 0.75. Density jecha kuvaka, unhu kwayo nguva dzose pakutsvaga nokuvapo mairi ivhu. Vavaki kushanda pamwechete nedzimwe kuchena - River chigadzirwa. It ane arambe achirema pamusoro 1,3 t. Per cubic mita. The arambe achirema nejecha uye ivhu zviri kare pamusoro 1,8 m. Saizvozvowo vhoriyamu.

Izvi zvinhu ndiyo hwaro kwemakore akawanda ejecha kongiri nziyo. Zvinonzi aida chaizvo paakapa migwagwa, pamwe-anoridza magirazi nyaya uye mune zvokurima.

Pakuvaka zvinokosha kuti pfungwa arambe achirema, unova nhamba mukanyiwa jecha kuti inzwi rayo, ine kuyerwa chikwata: g / cm3, makirogiramu / m3. Natural hombe arambe achirema jecha riri 1300-1500 makirogiramu / m3.

Bulk zvokuvakisa, nhamba iri shanduka uye kunoenderana mwero compaction. Zvinonzi kunzwisisa kuti zvakafanana chigadzirwa anotora yakasiyana chitsama. Density jecha kunokonzeresa runotsamira mwando chero zvakasiyana ayo zvazvinoita hombe arambe achirema. At yakakwirira mwando tsanga nokufukidzwa marongera remvura uye maererano uwandu jecha inowedzera zvinoshamisa. Kuti hombe arambe achirema pamusoro pejecha oscillation mwando paunoronga pakuverenga kuti chipimo chemushonga jecha kuti aida vhoriyamu. Kana musingadi kurangarira chinhu ichi, dhaka vachange vasina anodiwa yakachengeteka kumucheto uye kunopindirana ouinjiniya magadzirirwo achaita substandard.

Zvino ainyanya kushandiswa alluvial jecha, ayo mushoma iri nyore - kusuka jecha matombo. Izvi zvinoitwa sezvinotevera: hombe Vhoriyamu ndidiridze akageza ivhu uye guruva.

kuvaka jecha arambe achirema kunobva zviyo mamiriro. Somuenzaniso, mukuru mwero zvakananga uchapupu kuti sechikamu ayo gobvu, simba chaizvo uye kuchitonhora nemishonga mbeu. Ndiwo mashoko rurefu coefficient hunokosha kuti chivako permafrost ezvinhu. Ndiye hwaro mukuru-simba kongiri, yakanaka hardiness.

Density kuti Goldstone jecha vari nzenza ezvinhu hwokuratidza indekisi pamusoro 1500 makirogiramu / m3, asi anogona kuwedzera 1700 makirogiramu / m3. It kunoratidzwa yakanakisisa Utsanana unhu uye ndikandoshamba uye calcined yakaoma dzinongoitika zvinhu. Kana kushandiswa kuvaka kuona dzakakwirira Utsanana unhu vanogara. The arambe achirema pamusoro Goldstone jecha - mumwe parameter rinokosha chaizvo kuti inocherechedzwa nhoroondo panguva kuvakwa.
