Eziphathekayo. Iimpawu, khetha, Application.

Base, Iizilebhu floor, izakhiwo zentengiso pads eziphathekayo, umthwalo-ethwala ezindongeni - konke oku isiseko ngakumbi zokwakha eziphathekayo.

Eziphathekayo, ufakelo lwesamente yeyona ndlela iphambili ukwakhiwa kwezindlu monolithic eRashiya. Uphawu kwezi zakhiwo yintlanganisela iibhondi sisinyithi , kunye grout. Indlela ukukhetha udibaniso olunqwenelekayo neemeko zisetyenziswa okanye ezinye izinto Ndiza kuxoxa kweli nqaku,

Iimpawu eziphambili ngekhonkrithi, ebonakala licandelo wayo umgangatho:

1) amandla eziphathekayo (liboniswe isalathiso lwamanani, ngesiqhelo 7.5; 10; 12.5; 20; 25; 30). It ephawula uxinzelelo kwenxiwa eli eziphathekayo, kunokuba amandla ayo compressive e MPA (N / m2). Umzekelo, izinto eziphathekayo kwibakala B20 ixabiso umda we-20 MPA amandla. amandla eziphathekayo ikhangelwe yi ezikhethekileyo izixhobo umlinganiselo: ihamile Schmidt ihamile Kashkarova Onyx, njl

2) Water enganyangekiyo. Otyunjwe unobumba W kunye isalathisi ka-2 ukuya 20. Oku ubonakalise ubuninzi uxinzelelo intloko amanzi square sentimitha ye eziphathekayo, apho nganye iipropati eziphathekayo abazitshintshi.

Xa eyila izakhiwo ukusebenza kwiindawo ezinobutshaba (iziko lonyango amdaka, nomoya, imijelo eyenziweyo upper) ifuna ezongezelelweyo iindonga zingangenwa esisiseko. Kubonakala ukuba eqhelekileyo amanzi zemastic asphalt, okanye lokufaka ingqiqo yokulwela yokugquma seplastiki na ukusombulula le ngxaki. Kodwa asingabo bonke elula kangaka. Silnoagressivnyh ngoLwesithathu pogubno kuchaphazela izinto amanzi, itha mastiga yachithwa CO2 kwimeko bume yendawo kwaye weplastiki atyabukile. Kodwa kukho isicombululo. Ukusetyenziswa wajula amanzi - oku simse bume entsimbini. Yintoni na?! Gaze zingangenwa ibizwa crystallization ngamanzi additive ngaphakathi ngekhonkrithi, kwandisa vodonepronizaemost yayo indawo ubuncinane 1 (10-15%). Ziikristale kwezithako ngaphakathi ngekhonkrithi ezele porosity kunye kwii ukunyakama yasebenza pozlaschaya ukufuma isambuku kwaye crystallizes kwi pores. Brand eziphambili hydrophobes Penitron, Kristallizol. Umthamo iqhezu iziyobisi kwi concrete 12-12.5 kg. m3 ngekonkriti nganye.

3) uFrost. Ziphawulwe ncwadi F. It olwahlula inani kuxhotyiwe ukuqanda thawing of ngekhonkrithi, emva koko eziphathekayo angalahlekelwa iipropati yayo mechanical.
