Rangahau mō ngā āhuatanga pānga o te raima muka basalt
Tērā pea ka pāngia ngā hanganga raima e ngā pānga tūpono i te wā e whakamahia ana, ka hua ake he kino ā-rohe ki te hanganga, he pānga kino rānei pērā i te hinga o te hanganga, ka puta he mate kāore e taea te whakatika. Hei whakarite i te haumaru o te raima i roto i te āhua pānga, he mea nui kia akohia ngā āhuatanga pānga o te raima. Ko ngā āhuatanga pānga o muka pātarati kua tirotirohia te raima mā te whakamātautau SHPB, te whakamātautau pānga hama taka rānei.
I roto i te whakamātautau pānga i kitea ai ka taea e te whakaranu i ngā muka basalt te whakapai ake i te pakari pānga o te raima, te pakari pānga me te pikinga o te nui o ngā muka pātarati i whakaatu i te ia o te pikinga, kātahi ka heke iho, e whakaatu ana ngā rangahau e pā ana ko te nui o te ranu muka basalt 0.3% me te 0.36% o te mahi pānga o te muka basalt ki te raima ko te mea pai rawa atu; ki te whakatauritea ki ngā āhuatanga kino o te tauira, ko te whanaketanga o ngā kapiti me te kino whakamutunga ki te āhua o te whati, i kitea ko te muka basalt raima mō te kino kirihou, arā, ko te whakaranu i te muka basalt ka taea te mimiti pai i te kaha pānga ki te raima, ā, he pānga whakapakari i te raima. I te whakataurite i ngā āhuatanga kino o ngā wahi whakamātautau, te whanaketanga o te kapiti me te āhua whakamutunga o te whati kino, i kitea ko te muka basalt raima mō te kino kirihou, arā, i konatunatua ki ngā muka pātarati Ka taea e te raima te mimiti i te kaha pānga, ā, he pānga whakapakari i te raima. I rangahauhia e ngā kairangahau te ātete pānga o te muka pereki konukōre me te rōrahi o te muka pereki konukōre (0%, 0.4%, 0.6%, 0.8%) me te roa o te muka pereki konukōre (6mm me te 18mm) hei taurangi. I kitea ka taea e ngā muka pereki konukōre te whakapai ake i te pakari pānga o te raima, me te pakari pānga me te pikinga o te whakaranu muka me te nui haere; i te whakaranu muka kotahi, he pai ake te mahi pānga o te roa muka o te 6mm i te roa o te muka raima 18mm.
Hei whakarāpopototanga, muka pātarati Ka taea e te ranunga tāpiri te whakapai ake i te mahi pānga o te raima, engari kāore te ranunga muka tino pai i te ōrite, nā roto i tētahi tātari whakatairite i kitea ko tēnei āhuatanga i puta mai i te tikanga whakamātautau, te ōwehenga whakaranu raima, muka pātarati I roto i ngā whakamātautau ā muri ake nei, me whakapakari ake te kotahitanga o ngā āhuatanga e pā ana. Hei tāpiri, ko ngā rangahau o nāianei e aro ana ki te pānga o te horopeta muka ki tōna mahi pānga, ā, me whakahaere ā muri ake nei hei ako i te pānga o te tere taumahatanga me ētahi atu āhuatanga ki te mahi pānga.
