Concrete. Features, Options, Application.

Base, uriri Slabs, kongiri Mapedhi kushambadza zvivako, mutoro inobereka masvingo - zvose izvi hwaro yanyatsosimba kongiri kuvakwa.

Concrete, zvakasimbisa kongiri inzira huru monolithic dzimba kuvakwa muna Russia. A chiri zvivako izvi kunosanganisira esimbi zvisungo , uye grout. How kusarudza zvinodiwa mubatanidzwa ezvinhu pasi izvo zvavari kushandiswa kana zvimwe zvinhu Ndinenge munyaya ino,

The chikuru ehupfumi nekongiri, inozivikanwa ayo Qualitative zvinoriumba vari:

1) Concrete simba (achiratidzei kusanganiswa indekisi, kazhinji 7.5; 10; 12,5; 20; 25; 30). Rinoreva bvumidzwa vomanikidza kongiri, ndingadaro simba raro compressive muna MPa (N / m2). Somuenzaniso panguva chesamende mugwaro B20 muganhu kukosha 20 MPa simba. simba Concrete iri atariswa chaiyo kuyera Ezvemutauro: nyundo Schmidt sando Kashkarova zveonikisi, etc.

2) Water nemishonga. Varehwa tsamba W ane indekisi 2 kusvika 20. Rinoreva kunonyanyisa mvura musoro nevezera pa mativi sendimita nzvimbo kongiri, sezvamakaropafadzwa kongiri ehupfumi havasi achinja.

Kana mazano Zvivako uchishanda mamiriro ezvinhu akaoma (wastewater kurapwa Zvivako, aeration, abudise migero uye miseve) zvinoda dzokuwedzera inokosha mvura masvingo. Zvaizoratidza sokuti kwakajairika mvura yemastic Asphalt, kana akakonzera kubatana kwe epurasitiki kuputira anogona kugadzirisa nyaya iyi. Asi kwete vose nyore. Silnoagressivnyh Wednesday pogubno kukanganisa mvura zvinhu, bhitumini mastiga ichiputswa CO2 mune zvakatipoteredza uye mapurasitiki iri akasvuura. Asi pane mhinduro. Kushandiswa rakapinza mvura - ichi ndiyo yakanakisisa mhinduro kuti kungatikanganisa runyararo. Chii?! Rakapinza mvura iri nyore crystallization mvura chirungiso mu kongiri, anowedzera ayo vodonepronizaemost kanenge 1 nguva (10-15%). Crystals yokuvirisa mu kongiri akazadzwa porosity uye kupinda kwakaita mwando kusashanda pozlaschaya hombe unyoro uye crystallizes iri pores. Huru pezvitsiga hydrophobes Penitron, Kristallizol. Vhoriyamu chikamu pafuma kupinda chesamende 12-12.5 makirogiramu. por m3 nekongiri.

3) Frost. Kunoonekwa pamwe tsamba F. Rinoreva uwandu Zvinonzi nechando uye thawing nekongiri, pashure izvo kongiri asingadi chisanyanya zvemaziso ehupfumi.
