Konkire. Features, Mungasankhe yache.

Base, pansi slabs konkire nyumba ziyangoyango malonda, katundu mwankhanza makoma - zonsezi ndi maziko a analimbitsa yomanga ndi simenti.

Konkire, analimbitsa simenti ndi njira yaikulu yomanga monolithic nyumba ku Russia. Mbali A nyumba izi ndi osakaniza zomangira zachitsulo , ndi grout. Kodi kusankha kuphatikiza Napempha kwa mavuto amene amapezana ntchito kapena zipangizo ine m'nkhani ino,

The katundu chachikulu cha konkire, yodziwika ndi chigawo ake Mkhalidwe ndi:

1) Konkire mphamvu (atalonjeza index n'zosangalatsa kumva, imakhala 7.5; 10; 12,5; 20; 25; 30). N'zimenenso kuthamanga chovomerezeka pa simenti, m'malo mphamvu compressive mu MPa (N / m2). Mwachitsanzo pa mwala kalasi B20 malire kufunika 20 MPa mphamvu. mphamvu konkire ndi kufufuzidwa ndi wapadera zipangizo chingwe: nyundo Schmidt nyundo Kashkarova onekisi, etc.

2) Madzi kugonjetsedwa. Anatchulidwa kalata W ndi index wa 2 20. amadziwika pazipita madzi mutu kuthamanga pa lalikulu centimeter m'dera la simenti, ndi mmene katundu konkire sidzasinthika.

Pamene angagwiritse nyumba ntchito mwa mapangidwe ankhanza (madzi ogwiritsidwa ntchito malo chithandizo, aeration, njira ngalande ndi mikondo) amafuna zina lofunika kumatira makoma. Zingatanthauze kuti ochiritsira kumatira utomoni wonunkhira phula, kapena kusakaniza pulasitiki kutchinjiriza akhoza kuthetsa nkhaniyi. Koma si onse mophweka. Silnoagressivnyh Lachitatu pogubno bwanji zipangizo kumatira, phula mastiga kusungunuka CO2 mu chilengedwe ndi pulasitiki ndi wosendedwa. Koma pali njira. Ntchito ozama kumatira - ichi ndi yabwino yothetsera mapangidwe zikuwononga. Kodi izo? Ozama kumatira limangolembedwa crystallization kumatira zowonjezera auzidwa, kumawonjezera vodonepronizaemost ake osachepera 1 Mfundo (10-15%). Timibulu zina konkire wodzazidwa porosity ndi malowedwe a chinyezi adamulowetsa pozlaschaya chochuluka chinyontho ndi crystallizes mu pores lapansi. The zopangidwa waukulu hydrophobes Penitron, Kristallizol. Buku nusu ya thunthu mu konkire makilogalamu 12-12.5. pa M3 konkire.

3) Frost. Amalembedwa ndi kalata F. n'zimenenso chiwerengero cha m'zinthu wa yozizira koopsa ndi thawing konkire, kenako konkire sasiya katundu makina.
