“…Therefore, the compressive strength also decreases slightly. The results are aligned with the previous researcher's findings [42]. This condition is confirmed by a decrease in the compressive strength test results for SCC in the variant with the addition of PET fiber and fly ash powder.…”

“…This study also conducted non-destructive testing (NDT) with an ultrasonic pulse velocity (UPV) test as an alternative method, considering that the UPV test for concrete quality assessment has been in practice for decades. Previous studies have reported a good correlation between the SCC compressive strength and UPV test results [42,43]. However, specific studies on the application of NDT to concrete with plastic fibers having different densities and thermal conductivities compared to hardened concrete as a matrix still need to be made available, especially for the particular case of plastic fiber-reinforced SCC.…”

This study aims to utilize fly ash and waste PET bottles for producing more sustainable self-compacting concrete (SCC) with better mechanical strength. Fly ash is utilized as a supplementary cement material and waste PET bottles as fiber reinforcement to improve its flexural strength and achieve the targeted compressive strength. The experimental works were conducted on eight variations using 80 specimens, divided into two main groups of partial cement replacement using 0% and 15% fly ash by weight. The two variants are added with PET fiber based on the volume fractions of 0%, 0.25%, 0.50%, and 0.75%. Fresh concrete was tested using the slump flow method (T50) and the Visual Stability Index (VSI) based on ASTM 1611. The hardened concrete tests are conducted after 56 days and include testing the concrete's compressive strength, flexural strength, and ultrasonic pulse velocity. Test results showed that the presence of PET fiber in the SCC mix decreased its flowability. However, when added up to 0.75%, the mixes still meet the flowability requirements of fresh-state SCC. PET fiber addition tends to reduce the compressive strength, whereas the reduction in compressive strength of SCC with PET fiber without fly ash is insignificant. However, in SCC that uses fly ash, the addition of PET fiber causes a significant decrease in its compressive strength. Adding PET fiber into SCC mixes can increase flexural strength, both for the two variants: SCC without fly ash and SCC with fly ash. It can be concluded that PET waste fiber with an aspect ratio of 40 can be added up to 0.5% for SCC without fly ash and up to 0.25% by volume fraction for SCC with fly ash addition. The ultrasonic pulse velocity test results have an excellent tendency to predict the concrete's compressive and flexural strengths. Therefore, the UPV test can be applied for the non-destructive test evaluation of PET fiber-reinforced SCC. Doi: 10.28991/CEJ-2023-09-02-014 Full Text: PDF

“…Previously, research was often limited to the workability of fiber-reinforced concrete, such as the influence of fiber distribution on concrete fluidity and the influence of fiber length on concrete cohesion. Furthermore, mechanical properties are important in terms of whether materials or structures can meet the usage requirements, and thus, many experts have started to study the impact of various fibers on the basic mechanical properties of concrete [ 10 , 11 , 12 ]. M. G. Alberti and K. M. A. Hossain et al studied the effects of different fiber volume ratios on the basic mechanical properties of polyacrylonitrile fiber self-compacting concrete and polyvinyl alcohol fiber self-compacting concrete and concluded that with increasing fiber content, the splitting tensile strength of self-compacting concrete gradually increases and the compressive strength gradually decreases [ 13 , 14 ].…”

Pure self-compacting concrete has many disadvantages, such as early shrinkage and cracking. The addition of fibers can effectively improve the properties of resistance to tension and cracking of self-compacting concrete, thereby the effect of improving its strength and toughness can be achieved. Basalt fiber is a “new green industrial material” that has unique advantages, such as high crack resistance and being lightweight compared with other fiber materials. In order to study the mechanical properties and crack resistance of basalt fiber self-compacting high-strength concrete intensively, the self-compacting high-strength concrete of C50 was designed and obtained using the absolute volume method with multiple proportions. Orthogonal experimental methods were used to study the influence of the water binder ratio, fiber volume fraction, fiber length, and fly ash content on the mechanical properties of the basalt fiber self-compacting high-strength concrete. Meanwhile, the efficiency coefficient method was used to determine the best experiment plan (water binder ratio 0.3, fiber volume ratio 0.2%, fiber length 12 mm, fly ash content 30%), and the effect of fiber volume fraction and fiber length on the crack resistance of the self-compacting high-performance concrete was investigated using improved plate confinement experiments. The results show that (1) the water binder ratio had the greatest impact on the compressive strength of basalt fiber self-compacting high-strength concrete, and as the fiber volume fraction increased, the splitting tensile strength and flexural strength both increased; (2) there was an optimal value for the effect of the fiber length on the mechanical properties; (3) with the increase in fiber volume fraction, the total crack area of the fiber self-compacting high-strength concrete significantly decreased. When the fiber length increased, the maximum crack width first decreased and then slowly increased. The best crack resistance effect was achieved when the fiber volume fraction was 0.3% and the fiber length was 12 mm. Therefore, basalt fiber self-compacting high-strength concrete can be widely used in engineering fields, such as national defense construction, transportation, and building structure reinforcement and repair, due to its excellent mechanical and crack resistance properties.

Considering the challenges posed by agricultural waste, specifically rice straw, this study focuses on implementing cost-effective and eco-friendly processes to transform rice straw waste intovaluable, high-demand materials (sodium carbonate and M-25 concrete). The analysis of rice straw reveals its primary composition of cellulose and sodium silicate, with a layered cellulose microstructure. To produce sodium carbonate, rice straw is subjected to incineration ina furnace, with the resulting effluent gas passing through aqueous NaOH to effectively capture CO 2 at room temperature and ambient pressure. Simultaneously, the ash generated from burning rice straw is employed as a pozzolanic material in the production of M25 grade concrete.Notably, the concrete containing 20% ash demonstrates an impressive compressive strength of 29.05 MPa after a 28day curing period. These results are highly promising for the potentialutilization of agricultural waste in the production of soda and concrete.
