Te mau tao'a tahi mâmâ | Te mau rave'a haaparareraa parau teitei no te cellular concrete
Ua riro te simeni ei gel anoi no te mau tao'a e rave rahi e te mau anoiraa. Te mau tao'a mata e rave rahi, te mau faito taa ê o te mau tao'a, mau huru taa ê o te mau anoiraa, te mau faito taa ê no te anoiraa i te pape e te pape, Te mau faito faaohiparaa taa ê o te mau matini paturaa e te mau rave ohipa paturaa, E faatupu te mau huru paturaa taa ê e te mau huru tapearaa i te huru o te mau tao'a hu'ahu'a. Te mana rahi o te hoê ïa opuaraa paturaa o te mau rave'a aravihi apî. E faatupu te faaôraa ' tu i te mau tao'a atoa i te hoê taa - ê - raa rahi i roto i te huru o te hu'ahu'a. Āre'a, E mea faufaa roa te faito o te anoiraa i roto i te ohipa paturaa. Te faatumu nei teie tumu parau nahea ia faatitiaifaro i te mau fifi o te faaino i te huru o te mau tao'a i roto i te paturaa o te hoê hu'ahu'a hu'ahu'a.
1. The influence of material mixing ratio on project quality
As we all know, the mixing ratio of materials in the construction of foam concrete is the main factor affecting the quality of the project. E rave rahi mau mea o te faaino i te aravihi o te hu'ahu'a. There are many problems in quality control, and intelligent and automated construction machinery is still under further development. The mixing ratio, construction method, site management and other aspects of the cast-in-situ project of foam concrete are still in the initial stage of development. Tests have shown that the strength of the product can be increased within the optimum content of fly ash, and its strength will decrease after the optimum content is exceeded;
E parau mau atoa te reira no te sima. I muri a'e i te hi'opo'araa i te faito maitai roa a'e, its strength decreases as the amount of cement increases. This warns us that the optimal amount of materials must be controlled reasonably, E tia ia riro iho â râ ei mea papu a'e no te faaô atu i te mau hu'ahu'a mai te hu'ahu'a silica.
E faatupu te faarahi - roa - raa aore ra te au ore i te ino. Āre'a, the use of a mechatronics uniform speed measurement system for control is an ideal solution.
2 The influence and control of admixtures on the quality of foam concrete
E rave rahi mau anoiraa no te hu'ahu'a, te mau tao'a hu'ahu'a sima ihoa râ, mau rave'a vitiviti, e te mau rave'a no te faaiti i te pape. The matching parameters should be accurate. Mai te hoê tao'a hu'ahu'a sima, the control of the initial water-liquid mixing ratio and the control of the foaming rate will have a great impact on the quality of foamed concrete. The mixing ratio control of cement foaming agent and other raw materials is not accurate enough, which makes the construction quality not stable enough.
E nehenehe te faanahoraa no te faatere i te mau hu'ahu'a e faaohipahia ra i teie nei e amahamaha e toru tuhaa, oia ho'i, te faatereraa i te hoê pâmu, hose pump control and straw cross-section ratio control. I te tahi a'e pae, the gear pump control class is more accurate. Āre'a, most of the gear pumps currently in use are substitutes, o te nehenehe e faaohipahia i roto i te mau faanahoraa hydraulic, tera râ, e tia ia haamaitai i te faanahoraa no te faito i te hu'ahu'a, no te mea ho'i e, ua hamanihia mai te fare pâmu no te mono i te mau tao'a aluminium, and the internal gears are quenched by carbon steel. The hardness of the two parts is very different. No te ereraa i te hinu, E mea ohie roa ia oomo e ia faatupu i te taheraa toto i roto. Tamāhine, E mau hape to roto i te mau tauihaa carbone mai te ino ohie, ahu oioi, e te hoê taheraa toto rahi i roto, e ohipa oioi te reira i nia i te tanoraa o te faito. Te tumu, no te mea ïa e ua riro te tao'a hu'ahu'a ei tao'a taa ê i roto i te mana'o, tera râ, e rave rahi mau tao'a hu'ahu'a e ere i te mea ino roa aore ra e mea vaivai te hu'ahu'a, E vavahi te reira i te mau ravea auri carbone i roto i te pâmu pereoo i roto i te hoê faito e e haavitiviti i te ahu; I te horo'a i roto i, E huru ê to te tao'a hu'ahu'a iho. Mai te mea e, aita te reira e tamâhia aore ra e tamâhia i muri a'e i te ohipa, E mea ohie roa ia patu e ia opani i te tahua tufaraa i roto i te pâmu, o te faarahi i te patoiraa i roto i te pâmu, haavitiviti i te ahu, and increase the measurement error. Te rahi noa ' tura te faufaa, E faainohia te faito o te pape e te pape o te tao'a hu'ahu'a, Eita te huru o te hu'ahu'a e vai tamau, and the product quality of the foamed concrete will be directly affected. This is also an urgent problem that needs to be resolved.
