The zikuchokera konkire pa maziko

The zikuchokera konkire pa maziko. Zolowetsa a konkire pa maziko (miyala, mchenga, miyala) ayenera kukhala inequigranular kwa yunifolomu kudzazidwa voids zotheka. Ang'onoang'ono kusiyana, chindichepere ndiye ayenera mchenga ndi simenti kuthetsa iwo. Kuchuluka okwana malo opanda kanthu mu mchenga ndi kumanga mfundo pamwamba kuposa 37% ayenera kukhala pafupifupi 50% mu makhalidwe, osati oposa 45% mu miyala ya. Chiwerengerochi yerekezerani mosavuta. Pongotayira kapena osakaniza ayenera kunyamulidwa mu chidebe osiyana kuti tisagone, ndiye kutsanulira mtsinje zonyalazo kuti Mlomo wa. Mwa kuchuluka kwa madzi odzazidwa ndi n'zotheka kudziwa opanda buku. Mwachitsanzo, pamene madzi udzathiridwa malita 4.5, ndiye 45% voids.

The zikuchokera wonse wa simenti maziko muyenera kukatenga ntchito ochiritsira sieve. Chitsulo mauna sieve ndi 1, 0,5, 2, 4, 8 masentimita sieved mchenga ndi miyala, ndi mchenga kudzera 0,5,0,15, 0,3, 2.5 mm.

Konkire pa maziko. Konkire - osakaniza olimba a anasankha akaphatikiza, simenti ndi madzi. Brand simenti amagwiritsidwa ntchito limodzi limene ukhoza kugwedezeka kulola konkire kuuma mtima ankafuna. M'pofunika kuti miyala, madzi ndi mchenga, amene ntchito ndondomeko kuphika, anali pafupifupi woyera, mwinamwake adzakhala ndichepe mphamvu konkire. Misa, amene n'kuukanda, likukhalira nthawi zosiyana mu kugwirizana. Pamene misa amakhala wandiweyani, koma mapulasitiki, m'pofunika condense, ndipo anapitiriza kuchita ntchito zochepa. Ndipo pamene kugwirizana konkire ofanana achinyontho, ndi simenti zovuta, ayenera losindikizidwa ndi khola komaliza.

Osungunula simenti ndi kugawidwa ndi yokoka, pamene iwo mafomu mawonekedwe. Kuchuluka kwa madzi zimadalira mmene wandiweyani analandira konkire Kusakaniza. osakaniza ndi stratified pamene owonjezera chinyezi konkire, ndipo si koyenera kudikirira structural mphamvu konkire. Wangwiro ndi odalirika osakaniza mukhoza misa kwambiri wandiweyani a kugwirizana, ndipo mu nkhani iyi m'pofunika bwinobwino asindikize.

psinjika yolimba kwambiri ya konkire akhoza kulimbana kulikonse, ndipo ngati lidakali chifukwa angayambitse ming'alu. Kuonjezera mphamvu ya nyumba konkire umagwiritsidwa vavu zitsulo. Pa mphamvu apamwamba analimbitsa simenti chifukwa matenthedwe kuwonjezeka ofanana zolimba ndi simenti ndi olimba lumikiza amphamvu kuti kapangidwe wina.

Nthawi zina mavavu anaika wogawana pa misa simenti, ndi kuwotcherera mu chimango cha. Awa ndi cholimba konkire dongosolo. Kuika ndodo powapatsa zolimba mu akamaumba, m'pofunika osachepera 5 masentimita kuchokera pamwamba pa mwala. Pamene bwino correlate misa konkire ndi rebars kupeza yomanga yolimba kwambiri, anatha kupirira zinthu zonse.

Kodi kukonzekera konkire pa maziko? Aliyense akumvetsa maziko - maziko a zomangamanga onse ndi nyumba. Iwo ndi osiyana mitundu: maziko a midadada konkire, mizati konkire. Ambiri Mzere maziko abwino kwa dziko nyumba. Konkire ntchito m'magulu onse a zomangamanga, izo kwambiri adamfunsa zakuthupi.

Pakuti yokonza konkire zofunika: madzi oyera, mchenga, miyala. Ngati kumene zinyalala mu madzi, madzi kulitsuka. Miyala akhale 200% zosakwana madzimadzi, ndi madzi osachepera 75% kuposa simenti lapansi.

Pokonzekera konkire m'chilimwe, nthawi zonse ntchito madzi, ozizira okha kwa nthawi kolowera anachepetsedwa. Ndi madzi m'nyengo yozizira kuti konzekera kuti madigiri 60, kenako kuyamba konkire.

Kukonzekera konkire: kuchuluka kwa miyala, simenti, mchenga, anaika mu chidebe. Konkire sayenera zinthu zachilendo (nthaka, mafuta, udzu, dongo, etc.). Muziganiza zonse ndi kuwonjezera madzi. Ndiye kusokoneza kudzera mphanda mpaka yosalala. Popeza kupezeka konkire, m'pofunika ntchito kwambiri pa maola awiri poyamba, ndiyeno mphamvu yake yafupika.

Kumathandiza ayenera kudziwa zimene dongosolo konkire konkire pa maziko, momwe bwino kukonza kupanga maziko olimba.
