Універсальна мобільна установка для приготування ніздрюватих бетонів та результати випробування отриманих виробів

Abstract

The installation for the preparation of cellular concrete refers to the technological equipment of the construction sector, which is used for the preparation of various building mixtures, including mortars and other materials. The advantage of the machine is its ease of use and simplicity of design. The disadvantage is that the concrete mixer has a small mixing volume. The main task is to choose equipment for preparing aerated concrete. The problem is solved by the installation of a lid that closes tightly and makes it airtight, which makes the mixer especially effective for the production of cellular concrete. At the same time, the equipment retains its versatility, which allows to use it for other building mixtures. The production of aerated concrete includes mixing of raw components, pouring the mixture into the mold, swelling, pre-hardening, cutting and final hardening. Studying the compressive strength by applying a uniform increase in the loading of the sample until its failure allows to assess its bearing capacity. Increasing the cement content in the mixture helps to increase the strength of aerated concrete, but a significant amount of cement can negatively affect its thermal insulation properties. As the density of aerated concrete is less , in case of the less load it will be destroyed, but the evenness of the surface of the cube sample is also an important factor in the experiment. In addition to standard mechanical tests, it is advisable to use non-destructive testing methods, such as ultrasonic scanning and X-ray tomography, to assess the quality of aerated concrete. The versatility of the design allows the mixer to work with different types of mixtures, ensuring high productivity and product quality, and also adapting to various construction needs. Having considered the advantages of the proposed installation for preparing cellular concrete, several key aspects can be highlighted, namely: versatility, which allows the mixer to be used for various building mixtures and makes it possible to use it not only for aerated concrete, but also for other materials, such as fiber concrete and dry building mixtures.
