Te hu'ahu'a concrete e to'na taata hamani hu'ahu'a

Foam concrete is a new form of construction material that combines sand, aggregates and cement with foam making agent to produce lightweight, self-compacting and durable concrete. It is poured into a mould or a form and can be cut to different sizes for use in structural elements such as beams, slabs and walls. Foam concrete can be used in place of traditional forms or mortar and is much lighter than conventional concrete because of its thixotropic properties (ability to flow like a milkshake) that are derived from the interaction between the foam bubbles and the sand and aggregates in the mixture.

The workability of foam concrete depends on the water-cement ratio and type of aggregates. The higher the water-cement ratio, te rahi noa ' tura te pape i roto i te simeni e te ohie a'e i te ninii. Āre'a, ia hau atu ana'e te faito w/c i te otia maitai roa ' ' e, Te tupu nei te hoê hu'ahu'a simeni e te mau pore rairai e te mau pore tamau ore. E ohipa te reira i nia i te puai o te compression no te mea e faaruru te mau pore i te mau haapeapearaa [5,15]. E haamaitai te faaohiparaa i te mau hu'ahu'a taa ê i te aravihi no te rave i te ohipa. Te vai ra i roto te rehu manu, te mau hu'ahu'a fenua e te mau hu'ahu'a Portland. Te faaohipa-pinepine-roa-hia ra te rehu manu no te mea e faaiti te reira i te rahiraa sima e te anuvera o te pape, o te faatupu i te hoê maraaraa o te aravihi no te rave i te ohipa. I te horo'a i roto i, e faarahi te hoho'a o te rehu manu i te taheraa o te raima e to ' na pahonoraa i te pape.

Na te faaohiparaa i te RCA ei monoraa i te one e haamaitai i te aravihi e te mau huru o te hu'ahu'a, e te faarahi atoa ra te reira i te porosity no to ' na huru taata ore. Āre'a, e faahopearaa ino te reira i nia i te maroraa o te pape e te hutiraa mai i te pape.
