Te mau tao'a tahi mâmâ | Te mau rave'a haaparareraa parau teitei no te cellular concrete
TE Taata hu'ahu'a sima is a substance that is added to a concrete mix to form air bubbles which help the formation of lightweight concrete. The foam concrete can then be used in a variety of applications including insulation and thermal energy projects. The foamed concrete can also be pumped over great distances and heights. Taata hu'ahu'a simas are able to withstand high temperatures and are highly resistant to corrosion.
A slurry containing cement, fly ash and sand is combined with a foaming agent to form the lightweight concrete. The concrete is then pumped to the desired application site. It is important to note that foamed concrete does not swell upon exposure to water and therefore requires little or no hydration time.
This is a key advantage of the cellular concrete compared to conventional concrete. E faatupu te mau tao'a hu'ahu'a i te mau hu'ahu'a mata'i nainai roa o te faatupu i te hoê faito mata'i rahi a'e i roto i te simeni, o te faarahi i to'na puai e te pato'iraa i te mau tauiraa. Na te reira e haapuai a'e i te raima uira i te raima matauhia e e nehenehe atoa te reira e hamanihia i roto i te hoê vahi roa a'e ma te faaino ore i to ' na taiva ore.
I te rahiraa o te taime, e hamanihia mai te hoê anoiraa sima no roto mai i te hoê anoiraa sima, te hoê tao'a hu'ahu'a e te hoê mǎhu mai te haumi. No te hamani i te hu'ahu'a, e hi'opoahia te mǎhu i roto i te repo niu i te faaheporaa rahi. E ohipa te tao'a hu'ahu'a mai te hoê surfactant e e tauturu i te faarahi i te hepohepo o te repo no te hamani i te mau hu'ahu'a hau. Ua faatupu atoa te reira i te hamaniraa i te mau pore o te hu'ahu'a. Ia au i te huru o te surfactant i faaohipahia, E nehenehe te hu'ahu'a e faatupu i te hoê taa - ê - raa rahi i roto i to ' na tuhaaraa rahi o te pore, te aravihi e te taairaa.
