ڪاسٽ-ان-سيٽو فوم ڪنڪريٽ جي تعمير تي مواد جي ملاوٽ جي تناسب ۽ ڪنڪريٽ جي ملاوٽ جو اثر

Foam concrete is a mixed gel of various materials and admixtures. Different materials of raw materials, different material mixing ratios, different properties of admixtures, different water-to-liquid mixing ratios, different operation levels of construction machinery and construction personnel, different construction environments and curing conditions will all bring about the quality of foam concrete products. Great influence is a construction project of multi-variable control technology. The intervention of every variable parameter will make a big difference in the quality of foam concrete. تنهن ڪري, the mixing ratio in construction is very important. How to solve the related problems that affect product quality in the construction of cast-in-place foam concrete is the focus of this article.

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. The performance of foam concrete is affected by many factors. Fly ash can increase the strength of the product within the optimal dosage, and its strength will decrease after the optimal dosage. The same is true for cement. After the optimum dosage is exceeded, its strength decreases with increasing cement dosage. This warns us that the optimal dosage of materials must be controlled reasonably, especially the addition of trace elements such as silica fume must be more precise. Adding too much or unevenly will cause waste. تنهن ڪري, 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

There are many admixtures for foam concrete, mainly cement foaming agents, تيز ڪندڙ, and water reducing agents. The proportioning parameters should be accurate. Such as cement foaming agent, 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. The foaming agent control system currently in use can be divided into three categories, namely gear pump control, hose pump control and straw cross section ratio control. جي برعڪس, gear pump control is more accurate. بهرحال, the gear pumps currently in use are mostly substitutes, which can be used in hydraulic systems, but the foaming agent metering system needs to be improved, because the substitute gear pump housing is made of aluminum alloy, and the internal gear is quenched by carbon steel. In the case of poor lubrication, the aluminum alloy of the internal valve plate is very easy to wear and cause internal leakage. ان کان سواء, the internal carbon steel gear has defects such as easy corrosion, fast wear, and large internal leakage, which directly affect the measurement accuracy. The reason is that the foaming agent is a neutral substance in theory, but in fact many foaming agents are weakly alkaline or weakly acidic, which will corrode the carbon steel gears in the gear pump to a certain extent and accelerate the wear; The foaming agent itself has a certain viscosity. If it is not cleaned or cleaned after work, it is easy to build up and block the distribution channel in the gear pump, which will increase the internal resistance of the gear pump, accelerate the wear, and increase the measurement error The larger the value, the water-liquid mixing ratio of the foaming agent will be affected, the foaming quality will not be stable, and the product quality of the foam concrete will be directly affected. This is also a problem that needs to be solved urgently.
