1 The impact of material mixing ratio on project quality

The mixing ratio of materials in the foam concrete construction is the main factor affecting the project quality. Arụ ọrụ nke ụfụfụ ihe na-emetụta ọtụtụ ihe. Fly ash can increase the strength of the product within the optimal dosage, and its strength will decrease after the optimal dosage. Otú ahụ ka ọ dịkwa maka ciment. Mgbe oke usoro onunu ogwu gafechara, its strength decreases with increasing cement dosage. This warns us that the optimal dosage of materials must be controlled reasonably, karịsịa mgbakwunye nke ihe ndị dị ka silica fume ga-abụrịrị nkenke. Ịtinye nke ukwuu ma ọ bụ na-ezighị ezi ga-akpata n'efu. Ya mere, the use of a mechatronics uniform velocity measurement system for control is an ideal solution.

2 The influence and control of admixtures on foam concrete quality

E nwere ọtụtụ admixtures maka ụfụfụ ihe, tumadi simenti na-afụ ụfụfụ, accelerators, na ndị na-ebelata mmiri. The proportioning parameters should be accurate. Dị ka simenti na-afụ ụfụfụ, 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 foam concrete. Enwere ike kewaa sistemu njikwa ụfụfụ a na-eji ugbu a ụzọ atọ, ya bụ njikwa mgbapụta gia, hose pump control and straw cross section ratio control. Na ntule ndịiche, gear pump control is more accurate. Agbanyeghị, the gear pumps currently in use are mostly substitutes, nke enwere ike iji na sistemu hydraulic, mana ọ dị mkpa ka emeziwanye sistemu metering agent foaming, n'ihi na dochie gia mgbapụta ụlọ na-mere nke aluminum alloy, and the internal gear is quenched by carbon steel. N'ihe banyere mmanye mmanye na-adịghị mma, aluminum alloy nke esịtidem valvụ efere dị nnọọ mfe iyi na-akpata n'ime ime ntapu. Ọzọkwa, gia carbon nchara dị n'ime nwere ntụpọ dị ka corrosion dị mfe, eyi ngwa ngwa, na nnukwu ntapu nke ime, nke na-emetụta kpọmkwem nha nha. Ihe kpatara ya bụ na onye na-emepụta ụfụfụ bụ ihe na-anọpụ iche na tiori, ma n'ezie ọtụtụ ndị na-afụ ụfụfụ bụ alkaline na-adịghị ike ma ọ bụ na-adịghị ike acidic, nke ga-emebi carbon ígwè gia na gia mgbapụta ruo n'ókè ụfọdụ na mee ngwangwa eyi; Onye na-emepụta ụfụfụ n'onwe ya nwere ụfọdụ viscosity. Ọ bụrụ na anaghị ehicha ya ma ọ bụ hichaa ya mgbe ọ rụchara ọrụ, ọ dị mfe ịmepụta na igbochi ọwa nkesa na mgbapụta gia, nke ga-eme ka nkwụsi ike dị n'ime nke mgbapụta gia, mee ngwangwa iyi, and increase the measurement error The larger the value, A ga-emetụta oke ngwakọta mmiri-mmiri nke onye na-eme ụfụfụ, àgwà ụfụfụ agaghị eguzosi ike, and the product quality of the foam concrete will be directly affected. This is also a problem that needs to be solved urgently.
