What is lightweight concrete？
Shubka khafiifka ah ayaa badanaa lagu isticmaalaa dhismayaal injineernimo oo badan, iyo shubka fudfudud waxa loola jeedaa shubka lagu sameeyay isku daryo fudud oo khafiif ah iyo sibidh. Shubka khafiifka ah waa erey guud oo shubka leh cufnaanta bulk oo aan ka badnayn 1950kg/m3. So what types of lightweight concrete are included?
There are three main types of lightweight concrete
1. Lightweight aggregate concrete has an apparent density of 800~1950 kg/m3. Lightweight aggregates include pumice, volcanic slag, ceramsite, expanded perlite, expanded slag, dharbaaxo, iwm.
2. Hollow concrete (shuban xumbo leh, shuban hawo leh), its apparent density is 300-1000 kg/m3. Foamed concrete is made of cement slurry or cement mortar and stable foam. Aerated concrete is made of cement, water and gas generating agent.
3. Macroporous concrete (ordinary macroporous concrete, light aggregate macroporous concrete) has no fine aggregate in its composition. The apparent density of ordinary macroporous concrete ranges from 1500 ku 1900 kg/m3, and is prepared with crushed stone, soft stone, and heavy slag as aggregates. The apparent density of light aggregate macroporous concrete is 500-1500 kg/m3, and it is prepared with ceramsite, barar, broken brick, dharbaaxo, iwm. as aggregates.
