Babban kankare rarrabuwa

Nau'in kankare dogara ne a kan uku babban sharudda: ta nada, a wani talakawan yawa, kazalika da irin m a cakuda. Domin manufar da aka nufa, wannan abu ne a zahiri ya kasu kashi a jam'i na subclasses. Alal misali, a wasu yanayi bukatar hakan zafi juriya, a cikin wasu -. Tasiri juriya, da dai sauransu. A kowane hali, mafi kyau duka abun da ke ciki da aka zaba cewa ba da damar da tsarin ya karye lokacin aiki.

A general, wadannan rarrabuwa na kankare gina a kan manufar:

- manufa ta musamman kayan (amfani a high radiation yanayi a acidic muhallin, da kuma kamar).

- ga matafiya cakuda, hanyoyi, hadahada.

- al'ada kankare (an yi shi da tushe, da benaye, da dama karfafa kankare Tsarin).

- na'ura mai aiki da karfin ruwa samfurori (amfani ga samar da wani najasa, dams, canals, da dai sauransu).

Nau'in kankare yawa dogara a kan abin da irin m aggregates gabatar a cikin abun da ke ciki. Idan cakuda shi ne pumice, tuff, da kuma sauran porous yayan, shi iya auna daga 0.5 zuwa 1.8 ton da cubic mita (Hur da concretes, ciki har da wani slag kankare, pumice kankare, kumbura lãka). Domin samun wani musamman m samfurori (fiye da 2.5 ton / cu. Meter) ya gabatar a cikin kankare, karfe filings. Irin wannan cakuda da amfani a cikin halittar m Tsarin. Tã kankare (1.8-2.5 ton / cu. Meter) an hada da diabase, dutse ko farar ƙasa.

Kankare Nau'in kuma samar da wani cakuda matsananci-haske, kamar aerated kankare, aerated kankare ko foamed silicate. Da nauyi da cubic mita na kasa da rabin ton. Kankare wannan aji saboda da ya karu cellularity da low thermal watsin, amma low ƙarfi ne, kuma a lokaci guda. Saboda haka m, suna amfani da ta kayan.

kankare Nau'in da irin nauyin jamiái fiye da m. Mai ba yaduwa jamiái yau ne silicates tare da hanyar da curing a wani autoclave. Har ila yau infrequently samu garwayayye dangane da ruwa gilashi, stekloschelochnyh aka gyara abin da ake bukata domin samuwar zafi resistant kankare.

Mafi na kowa ne kayan dogara ne a kan gypsum, wanda yin datsa sassa, ciki ganuwar, kuma su sami wata cakuda da ruwa-resistant coatings. Bugu da kari, akwai suna yadu amfani da ciminti kankare (kamar Portland sumunti), slag-alkaline (a gwada sabon samfurin a cikin shiri kasuwar), polymer abun da ke ciki.

Rarrabuwa da kuma kaddarorin kankare ake bukata don ƙayyade da asali sigogi na cakuda da kuma nan gaba zane. A musamman, irin qagaggun ne ware halaye kamar da motsi (da ikon gudãna daga ƙarƙashinsu ƙarƙashin da kansa nauyi), ruwa juriya (a matsa lamba a wanda wani samfurin na 0,15 mita ne ruwa), da kuma wanda yake da muhimmanci sosai ga Rasha, sanyi. Alal misali, kankare F1000 alama zai iya tsayayya da dubban narke-narke hawan keke, wanda yana da muhimmanci musamman a yankunan da m weather, da kuma wani samfurin F50 na - kawai 50 irin hawan keke.
