What are the raw materials of la taaban karo xumbo?
The main components of foamed concrete are cement, dambas duuli, qiiqa silica, fiber, iwm. Some proportions have more cement content, and some proportions have less cement proportions, so specific problems must be analyzed in detail. Because foamed concrete is mostly cured under normal temperature conditions, iyo xaddi badan oo xumbo ah ayaa lagu daraa, these two factors determine that its cement ratio will be higher.
What is ALC?
ALC is the abbreviation of autoclaved lightweight concrete, which is a kind of high-performance autoclaved aerated concrete (ALC). ALC board is made of fly ash (or silica sand), sibidh, lime, iwm. sida alaabta ceeriin ugu weyn, and is cured by high-pressure steam to form a porous concrete sheet (containing processed steel reinforcement). ALC board can be used as wall material and roof panel. It is a new type of building material with superior performance. ALC board first appeared in Europe, and Japan, Europe and other regions have more than 40 years of production and application history. Hadda, the production technology and production equipment of domestic manufacturers are mainly imported from Japan and Germany.
Foam concrete is fundamentally different from ALC. Because ALC adopts autoclave, waxay inta badan ku tiirsan tahay falcelinta fuuq-celinta ee dambaska dukhsiga iyo lime ee kulayl sare iyo cadaadis si ay u soo saarto gelation. Cement is an auxiliary material.
While foam concrete is produced at room temperature, the active microaggregate will not quickly produce hydration reaction, iyo xumbodeeda adag ayaa wali ku xidhan saamaynta sibidhka ee sibidhka. Sidaa darteed, the mixing ratio of foamed concrete must be cement as the main body, iyo Saamiga sibidhka oo sarreeya.
Xaaladaha caadiga ah, the amount of cement should account for more than 30% tirada guud ee alaabta qalalan, iyo 30% should be the minimum use amount for its normal temperature curing. Marka lagu shubayo goobta, saamiga sibidhka waa in lagu xisaabtamaa in ka badan 60% ee wadarta alaabta qalalan. Heerkulka caadiga ah shubka xumbo leh cufnaanta hoose 600 kg/m3, saamiga sibidhka waa inaanu ka yarayn 70% ee wadarta walxaha. Marka cufnaanta hoose 400 kg/m3, the conventional proportion should account for more than 90% ee wadarta walxaha qalalan.
The following factors should be considered in the design of cement ratio:
(1) Noocyada sibidhka. Noocyada sibidhka oo leh xoog hore iyo goor dambe (sida sibidhka Portland-dual-degdega ah) waxay si habboon u dhimi kartaa saamiga sibidhka, iyo noocyada sibidhka ee leh awoodda dambe ee hoose ama xoogga hore ee hooseeya waa inay kordhiyaan saamiga sibidhka;
(2) Heerka xoogga sibidhka. High-strength grade cement (sida 42.5, 52.5, iwm.) can reduce the proportioning amount, iyo sibidhka heerka hooseeya waa inuu kordhiyaa qaddarkiisa;
(3) Tayada sibidhka. For large plants’ new dry-process rotary kiln cement, the mixing ratio can be appropriately reduced, while for small plants, shaft kiln cement or cement with a large mixing ratio should be appropriately increased;
(4) Density and strength requirements of the product. Cufnaanta hoose ama shuruudaha xoogga sare waa inay kordhiyaan saamiga sibidhka, cufnaanta sare ama shuruudaha xoogga hoose waxay yareyn kartaa saamiga sibidhka;
(5) Initial growth temperature. Heerkulka hore ee daaweynta ka dib marka la shubo (shubid) wuu hooseeyaa (<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) Variety and activity of active micro-aggregate (isku darka). Isticmaalka dhaqdhaqaaqa sare ee isku-darka-yar-yar ayaa yarayn kara saamiga sibidhka (sida ultra-fine slag), iyada oo la adeegsanayo isku-darka-yar-yar ee dhaqdhaqaaqa hooseeya (sida dambaska duqsiga sare) waxay kordhin kartaa saamiga sibidhka.
