This work investigates and improves the thermal dynamics of autoclaved aerated concrete (AAC) wall containing phase change material (PCM). The PCM is paraffin wax loaded into conical holes drilled into the AAC. Filled AAC with three different numbers of PCM-filled holes (2, 3, and 4 conical holes, which are designated as AAC-2H, AAC-3H, and AAC-4H, respectively) as well as the unfilled original AAC were both tested under two different conditions: indoors (with controlled temperature) and outdoors (with actual weather). For the indoor experiment, a heater was used as a thermal source and set up to maintain the testing temperature at one of three levels: 40 °C, 50 °C, or 60 °C. The wall temperature was then measured on the surface with each horizontally-positioned wall as well as four different positions at various depths below the surface of the wall. It was found that AAC-4H was the optimum condition, which can produce outstandingly a time lag of approximately 27%, reduce a decrement factor of approximately 31%, and also decrease the room temperature. This reached approximately 9% when compared with that of ordinary AAC at the controlled testing temperature of 60 °C. All samples were further tested in actual weather to confirm the thermal performances of AAC-4H. Thermal effectiveness of AAC-4H was improved by extending approximately a 14.3% time lag, which reduces approximately a 4.3% decrement factor and achieving approximately 5% lower room temperature when compared with ordinary AAC.

“…Analysis of the thermal parameters of various types of concrete is subjected to a number of studies [32][33][34][35][36], the results of which indicate the possibility of using the cement composite as the TES material. In addition, finding new methods to deposit ceramic wastes have a double positive impact on the environment.…”

Abstract:The paper presents the results obtained in the course of a study on the concrete made of aggregate obtained from wastes of sanitary ceramics. Previous examinations proved high in strength and durability of concrete of this type, and it showed a resistance to high temperatures. The material was classified as a fireproof concrete. While searching for the optimal applications of such concrete, a series of examinations and analyses on its thermal energy storage (TES) properties were performed. This paper describes the two-stage experiment on the thermal behavior of the concrete made with sanitary ceramic wastes during cooling processes in comparison to different building materials subjected to the same thermal conditions. On the basis of the thermal, infrared analysis, and suitable calculations, the thermal power and the ability of the composite to store thermal energy was estimated. Finally, it was stated that the concrete made of sanitary ceramic waste aggregate and alumina cement can be recommended as a heat-accumulating material, and in combination with high durability can be used, e.g., for the construction of fireplace bodies.

“…The new design of the monolithic lining of uidized bed furnaces was developed taking into account the requirements of regulatory documents of the Republic of Kazakhstan, and the requirements of foreign documents. Thus, the value of the concrete protective layer for reinforcement was determined in accordance with the requirements [5,15], and the results of scienti c tests [16,17].…”

The research purpose of the work is to extend the service life by experimental study of the performance of the liquid-layer furnace. Here, instead of large and small aggregates, the effect of the use of secondary refractory substances in reducing the cost of the concrete mixture is studied. The value of the study is to prove that heat-resistant concrete meets the technological requirements of a liquid-layer furnace, as well as experimental confirmation of the possibility of using secondary refractory materials as heat-resistant concrete aggregates. To solve this problem, it was proposed to replace the traditional method of facing the boiling floor furnaces (Fireclay brick of the SHB brand) with a monolithic concrete version. Considering that the technological feature of the boiling layer of the furnace is a high temperature up to 1000°C and an aggressive environment that causes SO3 gaseous sulfur, one of the well-known types of heat-resistant concretes, the sodium-infused liquid glass concrete type is selected as the base, and instead of cement, it is recommended to use liquid glass with low thermal conductivity, such as a material in the amorphous phase and a glass-layered composite viscous substance.
