Kedu ihe bụ akụrụngwa nke ụfụfụ ihe?

Ihe ndị bụ isi nke ihe na-emepụta ụfụfụ bụ ciment, ofufe utu, silica uzuoku, eriri, wdg. Akụkụ ụfọdụ nwere ọdịnaya ciment karịa, na akụkụ ụfọdụ nwere obere ciment, ya mere a ga-enyocharịrị nsogbu ndị akọwapụtara nke ọma.

Kedu ihe bụ ALC?

ALC bụ mbiri nke kọnkịrị dị fechaa autoclaved, nke bụ ụdị nnukwu arụmọrụ autoclaved aerated concrete (ALC). ALC osisi bụ nke ijiji ash (ma ọ bụ silica ájá), simenti, oroma nkịrịsị, wdg. dị ka isi akụrụngwa, a na-agwọkwa ya site na uzuoku dị elu iji mepụta mpempe akwụkwọ nwere oghere (nwere nkwado nchara edozichara). Enwere ike iji bọọdụ ALC dị ka ihe mgbidi na panel panel. Ọ bụ ụdị ihe owuwu ọhụrụ nke nwere arụmọrụ dị elu. Bọdụ ALC pụtara na Europe nke mbụ, na Japan, Europe na mpaghara ndị ọzọ nwere karịa 40 afọ nke mmepụta na ngwa akụkọ ihe mere eme. Ugbu a, teknụzụ mmepụta na akụrụngwa mmepụta nke ndị na-emepụta ụlọ na-ebutekarị site na Japan na Germany.

Ihe ụfụfụ bụ isi dị iche na ALC. N'ihi na ALC na-anabata autoclave, ọ na-adabere na mmeghachi omume hydration nke uyi ofufe na wayo n'okpuru nnukwu okpomọkụ na nrụgide iji mepụta gelation.. Simenti bụ ihe inyeaka.

Ọ bụ ezie na a na-emepụta ihe nkedo ụfụfụ na okpomọkụ ụlọ, Microaggregate na-arụ ọrụ agaghị emepụta mmeghachi omume hydration ngwa ngwa, na ụfụfụ siri ike ya ka na-adabere na mmetụta ciment nke ciment. Ya mere, Ngwakọta ngwakọta nke ihe na-afụ ụfụ ga-abụrịrị ciment dị ka isi ahụ, na oke ciment Ratio.

N'okpuru ọnọdụ nkịtị, ọnụ ọgụgụ nke ciment kwesịrị ịkọ karịa 30% nke ngụkọta ego nke ihe akọrọ, na 30% kwesịrị ịbụ opekempe ojiji ego maka ọgwụgwọ okpomọkụ ya. Mgbe ị na-awụsa na saịtị, oke nke ciment kwesịrị ịkọ karịa 60% nke mkpokọta akọrọ ihe. N'ihi na nkịtị okpomọkụ foamed ihe na a njupụta n'okpuru 600 n'arọ/m3, oke simenti ekwesịghị ịbụ ihe na-erughị 70% nke mkpokọta ihe. Mgbe njupụta dị n'okpuru 400 n'arọ/m3, ọnụ ọgụgụ nkịtị kwesịrị ịkọ karịa 90% nke mkpokọta akọrọ ihe.

Ekwesịrị ịtụle ihe ndị na-esonụ na nhazi nke cement ratio:

(1) Simenti dị iche iche. Ụdị ciment nwere ike dị elu n'oge na mbubreyo (dị ka simenti Portland na-agba ọsọ) nwere ike ibelata oke ciment nke ọma, na ụdị ciment na obere ike oge ma ọ bụ obere ike mmalite kwesịrị ịbawanye oke ciment;

(2) Ike ọkwa ciment. Simenti ọkwa dị elu (dị ka 42.5, 52.5, wdg.) nwere ike ibelata nha nhata, na simenti ọkwa dị ala kwesịrị ịbawanye oke nha ya;

(3) Ogo nke ciment. N'ihi na nnukwu osisi 'ọhụrụ akọrọ-usoro rotary kiln simenti, Enwere ike belata nha nke ngwakọta nke ọma, mgbe maka obere osisi, ciment ma ọ bụ ciment nwere nnukwu ngwakọta ga-abawanye nke ọma;

(4) Njupụta na ike chọrọ nke ngwaahịa. Obere njupụta ma ọ bụ ike dị elu chọrọ kwesịrị ịbawanye oke ciment, nnukwu njupụta ma ọ bụ ike dị ala chọrọ nwere ike ibelata oke ciment;

(5) Okpomọkụ mmalite mmalite. The mmalite ọgwụgwọ okpomọkụ mgbe wụsa (wụsa) dị ala (<25°C). The proportion of cement should be increased. When the initial curing temperature is high (25℃-45℃), the proportion of cement can be appropriately reduced. If steam curing or autoclave is used, it is still strong to reduce the proportion of cement;

(6) Ụdị dị iche iche na ọrụ nke mkpokọta micro-arụ ọrụ (admixture). Ojiji nke micro-aggregates na-arụ ọrụ dị elu nwere ike ibelata oke ciment (dị ka ultra-fine slag), ebe a na-eji obere mkpirisi arụ ọrụ dị ala (dị ka utu ijiji nke abụọ) nwere ike ịbawanye oke ciment.
