1. The influence of material mixing ratio on project quality
Bi gbogbo wa ti mo, the mixing ratio of materials in the construction of foam concrete is the main factor affecting the quality of the project. Awọn iṣẹ ti foomu nja ni ipa nipasẹ ọpọlọpọ awọn okunfa. 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;
Bakan naa ni otitọ fun simenti. Lẹhin iwọn lilo to dara julọ ti kọja, its strength decreases as the amount of cement increases. This warns us that the optimal amount of materials must be controlled reasonably, paapaa afikun awọn eroja itọpa gẹgẹbi fume silica gbọdọ jẹ diẹ sii kongẹ.
Ṣafikun pupọ tabi aiṣedeede yoo fa egbin. Nitorina, 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
Nibẹ ni o wa ọpọlọpọ awọn admixtures fun foomu nja, o kun simenti foomu òjíṣẹ, accelerators, ati omi idinku awọn aṣoju. The matching parameters should be accurate. Iru bii oluranlowo foomu simenti, 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.
Eto iṣakoso aṣoju foaming lọwọlọwọ ni lilo le pin si awọn ẹka mẹta, eyun jia fifa iṣakoso, hose pump control and straw cross-section ratio control. Ni ifiwera, the gear pump control class is more accurate. Sibẹsibẹ, most of the gear pumps currently in use are substitutes, eyi ti o le ṣee lo ni eefun ti awọn ọna šiše, ṣugbọn eto wiwọn aṣoju foaming nilo lati ni ilọsiwaju, nitori awọn aropo jia fifa ile ti wa ni ṣe ti aluminiomu alloy, and the internal gears are quenched by carbon steel. The hardness of the two parts is very different. Ninu ọran ti lubrication ti ko dara, Aluminiomu alumọni ti awo àtọwọdá inu jẹ rọrun pupọ lati wọ ati ki o fa jijo inu. Jubẹlọ, awọn ti abẹnu erogba irin jia ni o ni awọn abawọn bi rorun ipata, yara yiya, ati ki o tobi ti abẹnu jijo, eyi ti o taara ni ipa lori išedede wiwọn. Idi ni pe oluranlowo foomu jẹ nkan didoju ni imọran, ṣugbọn ni otitọ ọpọlọpọ awọn aṣoju foaming jẹ ipilẹ alailagbara tabi ekikan ailera, eyi ti yoo ba awọn erogba irin jia ni jia fifa soke si kan awọn iye ati ki o mu yara awọn yiya; in addition, Aṣoju foomu funrararẹ ni iki kan.

Ti o tobi ni iye, ipin idapọ omi-omi ti oluranlowo foomu yoo ni ipa, didara foomu kii yoo jẹ iduroṣinṣin, and the product quality of the foamed concrete will be directly affected. This is also an urgent problem that needs to be resolved.
