Konkire chabwino: specifications, GOST

Chabwino simenti ndi chuma nyumba za ulemu. Izo ntchito pa nthawi imene ntchito ochiritsira konkire katundu n'zosatheka. Izi pazikhalanso caulking, mudzaze gustoarmirovannyh kumanga ndi makonzedwe a kumatira lapansi. Koma pamaso kukonzekera osakaniza ayenera dziŵani okha ndi specifications ake komanso mbali.

makhalidwe luso

Tafotokozazi ndi yowona structural chuma, analenga zochokera simenti. Pamene zosakaniza zofunika kuchita raznofraktsionny mchenga ndi madzi. Mtundu wa simenti amatchedwanso mchenga, ndi chachikulu kwagona kuti nusu ya particles nkhani zikuchokera sayenera oposa 2.5 mm.

osalimba a olemedwa ndi owonjezera konkire katundu lingayambire pakukhala 2200 ndi 2500 makilogalamu / m³. Akuchiritsa kutentha akhoza kukhala wolingana ndi malire a +5 kuti +30 ° C. Luso kupirira kuthamanga anakhalabe pa 25 MPa. mphamvu Compressive ndi 18,5 MPa, ndi nkhani ya mawerengedwe a kukana, ndi lofanana 14.5 MPa.

Frost kukana zingasiyane malingana ndi zosakaniza ntchito, ndi osiyanasiyana kuchokera m'zinthu 50 1,000 wa yozizira koopsa ndi thawing. Chabwino konkire ali enaake a madzi kukana. chizindikiro Izi zinaperekedwa mwa kalata «W» ndipo mwina zizigwirizana osiyanasiyana kuchokera 2 20.

Features zina

Katundu ndi zabwino-grained konkire angathe kugwira mawonekedwe anakonzeratu panthawi imodzi, zimakhudzidwira chiŵerengero simenti ndi mchenga komanso madzi. Ngati ndi mafuta zosakaniza, iwo akhoza kukonza mu chiŵerengero cha 1 1 kapena 1 1.5. Mu njira zimenezi, mbewu imakonzedwa pa mtunda Chrixitu.

Ngati kuchuluka kwa binder yafupika, izo adzachititsa kuchepa vodopotreblyaemosti ndi kuyenda. Chabwino konkire zaphindu cholinga akhoza kukhala okonzekera m'mbali zotsatirazi: 1: 3.5 ndi 1: 4. Konkire adzakhala viscous, ngati zili mchenga udzakhala wautali. Plasticity patsogolo ndi Kuwonjezera wa madzi ndi plasticizers. Ngati inu kuchepetsa simenti, zingayambitse kulekana.

chifukwa umboni wa

Ntchito kufanana mulingo woyenera kwambiri kusanganikirana konkire, inu adzaonetsetsa kachulukidwe yachibadwa pa ntchito zoyendayenda. Ngati ntchitoyo yakhala ikuchitidwa molondola, chabwino-grained konkire adzakhala ndi osalimba ndi mkulu, pachilichonse wabwino, kukana chinyezi ndipo durability wa kupinda ofananira. Chisanu kukana mwa zinthu kuchuluka, pamene gawo chabwino ndi kuyenda yachibadwa kugawira osakaniza mofulumira ngati nkotheka. Mwa mbali zabwino mwa nkhani - ndi mtengo wotsika, amene anakhudzidwa ndi pakalibe akaphatikiza coarse. Izi mosavuta kunyamula. Mwazina, simenti amapereka zosiyanasiyana.

Kuchuluka kwa ntchito

Konkire katundu chabwino ndipo angagwiritsidwe ntchito m'madera kuda coarse kuchepekedwa akaphatikiza. Pamene kusanganikirana ntchito kukweza la simenti, imene akhozanso kukopeka ndi mavuto kusankha chiŵerengero cha magulu. Koma kuipa ndi kulipidwa ndi ndalama mu mayendedwe a mwala wosweka ndi miyala.

Makhalidwe a monolith akhoza bwino pogwiritsa ntchito plasticizer kuchepetsa ndalama komaliza. The polima filler akupanga kukana zinthu chilengedwe ndi mwamakani madzi ndi chisanu. Concretes katundu ndi zabwino, mawu luso omwe atchulidwa pamwambapa ntchito monolithic ziwembu pomwe zovuta Mwachitsanzo:

• woonda-mipanda partitions;
• anawasema ndi domes;
• mu kupanga ziboliboli paki;
• mapangidwe njira, akasinja ndi mipope;
• pamene wobala amaika mumsewu miyala ,
• amaika mumsewu slabs ndipo kumathandiza kuchepetsa;
• mu kupanga za ubwenzi wa pamakoma zambali ndi chipewa;
• pomanga nyumba hayidiroliki;
• pamene kupanga kudenga arched.

Yomanga imeneyi zikuchokera kungakhale mayikidwe pamalo. Ngati inu ntchito simenti kalasi B25, ndiye zingakhale chitsulo simenti pansi, kusindikiza mfundo ndi ming'alu mu mpanda.

Ubwino waukulu ndi kuipa

Zabwino-grained konkire, amene zikuchokera amatchulidwa m'nkhani, zambiri ubwino, m'pofunika kusiyanitsa pakati pawo:

• Mkulu mphamvu chiŵerengero;
• kuthekera kupanga zipangizo ndi katundu wapadera;
• zonyamula katundu kugwedera;
• yunifolomu dongosolo;
• Kuthekera yozindikira kusakaniza.

Komabe, nkhani ali ndi kuipa kwake, iwo MUKACHULUKIDWE mowa okwera simenti, ndi kuuma mkulu ndi shrinkage mankhwala kuponyera. Pankhani kuuma, zikhoza kusokoneza mankhwala.

The zikuchokera ndi boma miyezo

Kupanga zinthu anafotokoza ntchito GOST, concretes katundu ndi zabwino, specifications zomwe zimatchulidwa m'nkhani chopangidwa ntchito zigawo zikuluzikulu za simenti ndi madzi. Koma kumadzazidwa kungakhale mtsinje mchenga ndi miyala. Mbali yoyamba, kachigawo sayenera upambana mlingo wa 2.5 mm. Atavutika mwina zidzawonjezedwa ngati tinthu kukula kwake si upambana 10 mm. Komanso, kuwonjezera kuti, pophika dongosolo angawauze kufunika plasticizers. Izi zimathandiza kuti tikwaniritse dongosolo homogeneous.

Powonjezera simenti mu kuchuluka lalikulu kuposa chofunika, inu zingachititse njira kuti adzakhala omangika mu zomangamanga ndi. Ngati pophika izi anawonjezera ndalama zochepa, ndiye pambuyo kuchiritsa zinthu adzakhala ndi mphamvu otsika. Konkire mwakhama ndi zabwino-grained (GOST 7473-2010) akhoza kupangidwa ndi mafunde otsika. Njira imeneyi anafotokoza kuti kupanga malire, zitsime zosambiramo, kuphatikizaponso komanso amaika mumsewu slabs. Pankhani ya nyumba woonda-mipanda ntchito njira wandiweyani ikuthandizira. Zinthu zimenezi nthawi zambiri zimakhala maziko a kali msewu, ngati ali mkulu madzi kukana ndi kukana ozizira.

Zimaonetsa filler

Chabwino zigawo konkire ayenera anasankha kutenga nkhani malamulo. Njira yothetsera ayenera muli zigawo kuti ndi makhalidwe osiyana. Malamulo amayendetsa ntchito mchenga, pa kukula kwa kugawanika kwa. Choyamba, mchenga ndi anasefa kupyolera mu chophimba, lomwe mbali 2.5 mm. Zimenezi zimathandiza nusu choyamba. Kenako gululi ntchito ndi kukula mauna a 1.2 mm.

Pambuyo selo yafupika, iwo ayenera kutsatira kukula kwa 0,135 mm. Onse amene adzadutsa ukondewo nthawi yotsiriza, zidzagwiritsidwanso ntchito monga filler a. Zabwino-grained konkire ayenera kukhala okonzeka kugwiritsa ntchito gulu loyamba la mchenga mu buku la 20 mpaka 50% ya kulemera okwana. Buku yotsalira adzakhala yaing'ono kukamphindi.
