Kodi knead konkire: chiwerengero (tebulo)

Musanayambe kusakaniza konkire, chiwerengero cha zomwe anatchula pansipa, zigawo ayenera anasankha molondola. Kunena zoona, simenti ndi osakaniza, zochokera - aggregates zosiyanasiyana ndi simenti. Choncho, konkire lili miyala, miyala, miyala, mchenga ndi simenti. Mwa zina, chapadera zina mtundu wa plasticizers angagwiritsidwe ntchito. ntchito yawo ndi opatsa zina zimatha konkire. Tingasiyanitsire makhalidwe chachikulu cha konkire, chimene chiri ndi mphamvu compressive. Potengera yankho mphamvu pambuyo kuumitsa izo lagawidwa chizindikiro.

The zikuchokera konkire

Ngati mukuganizira mmene kusakaniza konkire, chiwerengero cha zomwe zalembedwa mu nkhani, choyamba muyenera kudziwa mtundu losavuta konkire wapangidwa ndi simenti ndi mchenga coarse. Chotero njira kawirikawiri ntchito monga gawo lapansi mu nyumba maziko. Pamene zikuchokera izi ananenanso mu pang'ono madzi njira atapeza kachulukidwe ka mtundu chonyowa nthaka. Ngati pali kufunika kukonzekera cholimba konkire, m'pofunika ntchito monga placeholder chomenyedwa, factionalism amene zimasiyanasiyana mamilimita 3 mpaka 35 mm.

kusankha kufanana

Musanayambe kusakaniza simenti, chiwerengero ayenera kufufuza. Zolinga zosiyana muyenera kukonzekera konkire nyimbo zosiyanasiyana. Mwachitsanzo, ngati akuyenera kupanga balusters, kusankha filler, kusiyana ndi amene ali ndi sing'anga kapena kachigawo chabwino. N'chimodzimodzinso ndi kudzaza ziwiya munda, zinthu kukongoletsa ndi masitepe. Ambiri makulidwe ntchito yokonza konkire amaonedwa 1: 3: 6, ndi kulemekeza simenti, mchenga ndi akaphatikiza. Mwa zina, m'pofunika ntchito theka kapena gawo limodzi la madzi, zomwe kudzayesedwa ndi flowability chofunika wa njira.

Ngati mukuganizira mmene kusakaniza konkire, chiwerengero cha zipangizo ayenera kuwaganizira, koma m'pofunika kulabadira zikuchokera zosakaniza. Choncho, ngati mchenga uli ndi apamwamba mnyontho kuposa masiku onse, ayenera Pre-zouma, monga adzakhala chidwi kwambiri ndi kulemera, kuposa kuti chofunika kwa yokonza njira yolondola. N'chimodzimodzinso ndi miyala.

The kufanana kwa yokonza mtundu winawake wa simenti

Pofuna kukonza konkire M100 mtundu wa simenti M400, muyenera kugwiritsa ntchito simenti, mchenga ndi miyala mu chiŵerengero zotsatirazi - 1: 4.6: 7. Koma kupanga kalasi konkire M 150 zidzakhala zofunikira kuti akonze zipangizo zonse yomweyo, koma mu chiŵerengero yosiyaniranapo, simenti kuti ntchito mu kuchuluka kwa chiwalo chimodzi, pamene mchenga ntchito kuchuluka kwa 3.5, koma chomenyedwa ndi kuchitidwa mu chiwerengero 5,7. Pokonza simenti M200 zidzakhala zofunikira kukonzekera zipangizo zalembedwa mu chiŵerengero cha 1: 2.8: 4.8. Kuti akonze njira 250 chizindikiro M, m'pofunika kukonzekera zipangizo pa chiŵerengero cha 1: 2.1: 3,9. Kuti akonze njira M mbuye 300 adzatenga zinthu mu chiwerengero cha 1: 1,9: 3,7. Konkire chizindikiro M 400 analandira ngati feedstock ntchito mu chiwerengero cha 1: 1.2: 2,7. Konkire chizindikiro M amapita 450, ngati tigwiritsa ntchito chiŵerengero 1: 1.1: 2.5.

The zofunika zigawo zikuluzikulu

Pamaso kusinja konkire, chiwerengero ayenera ankaphunzira. Koma m'pofunika osati kusunga zinthu zoyenera, komanso kuganizira zinthu zimene zikugwira ntchito pa aliyense zikuluzikulu za njira. Mwachitsanzo, ngati inu ntchito mtundu simenti M 400 m'malo M 500, pambuyo dongosolo solidification sadzakhala wamphamvu. Mulimonsemo, mpheto za konkire sakhoza kutulutsa pa kutentha m'munsimu 16 ⁰ C. Ngati panafunika, izo zidzakhala zofunikira kugwiritsa ntchito plasticizers.

Pamaso kusinja simenti, kutalika odziwika bwino. Nkofunika kulabadira chikhalidwe cha munthu zigawo zikuluzikulu. Simenti, Mwachitsanzo, amayenera kukhala mfulu madzi, komanso youma. Musati kugula simenti, amene wapangidwa ndi apezeka kapena chinyezi mkulu. Sikuti kugula mankhwala si zaikidwa. Ndi bwino kukhala ndi simenti basi isanayambe ntchito, monga pa yosungirako ndi anatha kupeza chinyezi ndi kutaya khalidwe lawo. nthawi otero kupeza simenti - masabata 2 isanayambe ntchito.

Zimafunika mchenga

Ngati mukuganizira pa funso mmene knead bwino anapangira konkire kukonzekera ake Tingaone pamwamba. M'pofunika kuganizira khalidwe la mchenga, zomwe zigwiritsidwe ntchito pa ntchito. Konkire bwino ntchito mchenga factionalism amene zimasiyanasiyana 1.5 5 mm. Ndi bwino kugwiritsa ntchito mchenga yunifolomu kukula, kapangidwe kake sayenera zosafunika. Samalani kuti mumchenga panalibe zomangamanga zinyalala ndi mbewu zatsalira. Pamaso pa onse a zigawo izi zikhoza kubweretsa kusintha pa khalidwe la konkire. Kamodzi mwaphunzira, zimene anapangira kusakaniza konkire, inu mukhoza kuyamba ntchito. Koma si koyenera kugwiritsa ntchito zipangizo zimene aone khalidwe. Choncho, kudalirika kwa mchenga makamaka anadutsa sefa. Iwo akulimbikitsidwa apamwamba konkire ntchito mtsinje mchenga, ngakhale kuti ndi wokwera mtengo kusiyana ndi amene amatchedwa gullies.

fillers

Ngati mukufuna kudziwa mmene kusakaniza konkire, chiwerengero cha tebulo kudziwa. Nkofunika kuganizira komanso khalidwe la aggregates lapansi. Zimapatsa mphamvu konkire pambuyo kuchiritsa. Kotero, musati ntchito nthawi zonse kapena nyanja timiyala, amene ali pamwamba yosalala ndi sizitanthauza ukapolo ndi njira. Ndi bwino kugwiritsa ntchito zinthu zimene zakhala zosamveka chikhalidwe. Mwa zina, ntchito yokonza konkire, njerwa ndi simenti, amene ali mphamvu zokwanira, koma pa nthawi yomweyo ali ndi kulemera otsika. Kusankha miyala kachigawo ayenera kutsatira mu osiyanasiyana mamilimita 8 mpaka 35. Chachikulu magulu zinthu ntchito kupanga, amene ali osowa kwambiri. Pankhaniyi, nayenso, n'kofunika kuganizira mfundo yakuti fillers ayenera kukhala zochepa za inclusions extraneous dongo. Ngati ndi kotheka, muyenera kumasula zopangira kwa zinyalala yachilendo. Nkofunika kusankha filler, amene ali pazipita padziko roughness. Izi kuonetsetsa mkulu khalidwe la zowalamulira pa.

zigawo zina

Ngati mukuganizira mmene kusakaniza konkire mu chosakanizira simenti, kuipa tafotokoza angagwiritsidwe ntchito mwa inu. Nkofunika musangoganizira ubale komanso kufunika zigawo zina. Laimu akhoza kusiyana pakati pawo. Pa ayankhidwa pansipa. Izo ntchito pamene kusanganikirana wabwino njira khalidwe madzi. Ziyenera kukhala oyera, sayenera inclusions mu mawonekedwe a zidulo ndi alkalis. Ndi zosavomerezeka ntchito yosakongola kapena mtsinje, nyanja madzi. Madzi oyenera kumwa, angagwiritsidwe ntchito yokonza konkire.

zina

Ngati pali kufunika kuti konkire mosavuta stacking, angagwiritsidwe ntchito ndondomeko kusakaniza zikuchokera laimu. Pambuyo kuwayika njira inakonzedwa ndi ntchito zake, kudzakhala kosavuta kutsegula pamwamba. Koma M'pofunikanso kukumbukira kuti laimu ndi kuteteza simenti pamodzi ndi filler, amene ali zikuchokera, amene akhoza kwambiri bwanji mphamvu. Choncho, ntchito ya laimu kapena ayi, muyenera kusankha mbuye. Musaganize kuti ntchito zake zingakhale zovuta kwambiri, si koyenera kuzimitsa okha. M'malo mwake, mukhoza kugwiritsa ntchito ready- slaked laimu anagulitsa mu masitolo a zomangira.

pomaliza

Musanayambe kusakaniza konkire, kuipa (iwo amasiyana chosakanizira cha) ayenera mosamala. Izi adzapereka apamwamba konkire, amene pambuyo solidification amakhala ndi durability mkulu.
