Description

ANYTHING TO IMPROVE THE STRENGTH PERFORMANCE OF CONCRETE WASTE FIBERS USED AS IS, WITHOUT PROCESSING. TECHNICAL FIELD This invention can be used in structures where bending strength is important. without any processing to increase the strength performance of concrete It is related to waste fibers that are used as is. STATE OF THE ART The flexural strength of traditional concrete is approximately the same as its compressive strength. It is known to be one in ten. Flexural strength is both a strength and a tenth of the characteristic of concrete. This is of great importance in terms of service life (Bırıcık Ö., et al., 2023). To increase the flexural strength of concrete, both micro and macro-sized fibers are used. These fibers are used. Depending on their size, these fibers exhibit different functions in concrete. It improves performance. However, the production processes of the fibers used are long and... It is costly. For example, polypropylene fibers have high polymer raw materials. Basalt fibers are produced by melting and shaping them at various temperatures. Despite being produced, very high temperatures are still required to bring it to fiber length. It is used. Considering the global climate crisis, its production is high. It prioritizes the research of alternative products to replace energy-consuming products. Accordingly, the high value of materials that are generated as waste in the production of another product Using it as a replacement for materials that require energy to produce offers significant advantages. It provides. Previous technical research has shown that waste fibers are used in some studies. This is observed. One of the files found during the investigation regarding this matter is: It is a lightweight fiber-reinforced concrete based on industrial waste, with the number RU2781487C1. It is related to that. 2 Described as a similar study in document number RU2781487C1 the study's hazardous waste resulting from production and consumption It is observed that it is used. The other document is numbered CN112408827B and concerns recycled concrete and... It is related to the method of preparation. The other document is numbered CN114507044B and concerns high-strength environmental materials. It is related to the type of concrete and its preparation method. Although the three documents mentioned above are similar in subject matter, their advantages are... In terms of the solutions they offer and the materials used, they are included in our current application. The site does not meet the requirements in terms of space, materials, and solutions. DEFINITION OF INVENTION The invention in question overcomes the disadvantages described in the current state of the art. It provides and meets needs. This invention is suitable for structures where bending strength is important, such as beams and concrete that can be used as an alternative to reinforcement fibers in floors without undergoing any processing to improve its durability performance This is related to waste fibers used in g�b. Regarding the invention in question, the state of the art as mentioned above is primarily relevant. When we consider the differences between similar topics; In the known state of the art, as mentioned in document number RU2781487C1 The study examined waste classified as hazardous, originating from production and consumption. It is observed that waste materials are used in our invention application. The materials are known to pose no danger. 3 In document CN112408827B, it is stated that the fibers, which are indicated as waste, are mixed with various materials. It is observed that a pre-treatment is applied by mixing. In this respect, the invention in question... Our application differs from theirs in terms of similarity. In document CN114507044B, and also in document RU2781487C1 Asbestos fibers, which are considered potentially dangerous, have been used. Our proposed invention, which poses no danger, appears to be separated by fibers. Tensile strength compared to the high compressive strength performance exhibited by concrete. It is known to have very low strength (Latif et al., 2021). It is brittle. By using fibers in concrete, a more ductile structure is created, thus improving mechanical properties. Improving their performance is a widely researched topic (Mardan- Aghabaglou et al., 2018). Concrete containing materials such as steel, basalt, polypropylene and polyethylene. It has been understood that various types of fibers were used. The type, length, and delicacy of the fibers used... many factors such as ratio, geometry, usage amount, tensile strength and surface properties Depending on the parameter, it affects the strength, crack control, and deformation of concrete. It is expected to improve capacity, impact resistance and durability. (Mardan-Aghabaglou et al., 2019; Yazıcı Ş, et al., 2023). Concrete in its composition, completely waste and without any pre-processing Investigating usable fibers will enable the reuse of waste. It is important both in terms of recognition and contributing to the circular economy. Textile materials, due to their lightness, flexibility, easy availability, antibacterial properties, durability, and desired features. Widely used in concrete mixes thanks to advantages such as manufacturability in various sizes. It is used as (Mardan-Aghabaglou et al., 2013). From textile waste Various surfaces were used so that the created fibers do not negatively affect the fiber-matrix bond. It is understood from the literature that modification processes are applied. These processes are carried out for this purpose. The processes initially include plasma, UV, ozone, and UV-ozone surface modification. This has been emphasized. However, an additional process is needed both in terms of energy consumption and cost. waste fibers that can be used in concrete composition without needing additional materials This needs to be investigated. The waste used within the scope of our application. Table 1 shows that the fibers increased the compressive and flexural strength performance of the concrete. This is observed. Furthermore, the effect of fibers on the spreading performance of cementitious systems is also studied. 4 This is shown in Figure 1. The naming of the mixtures in the Figure and Table is based on the composition of the mixture. It is made according to the type of fiber it contains and the fiber dosage. For example, fiber 1-25; air conditioning dust waste. It is described as a mixture containing 0.25%. Furthermore, the prepared... To examine the performance of fibers in cementitious systems more clearly. Each branch has been used separately. Each result is given as the average of 3 samples.
