Waste tyres have been an increasing problem every year due to the increase in vehicle sales. In Indonesia, more than 50 million waste tyres were generated every year. However, materials in waste tyre such as textile and steel fibers, actually, can be used to improve the mechanical properties of the concrete. Recently, some researchers have been devoted to the utilization of steel fibers extracted from the waste tyre (SFEFWT) on the concrete. This study focuses on the investigation of SFEFWT effect on the concrete containing palm oil fuel ash (POFA). Steel fibers were extracted from waste tyres by manually cutting process and being cut to 1 inch (25.4 mm) length. A number of cylindrical and beam specimens of concrete containing 15% palm oil fuel ash by being partially replaced the weight of cement, with addition 0.25%, 0.50%, 0.75% and 1% SFEFWT were cast and tested. The mechanical properties such as compressive, tensile and flexural strengths at the age of 28 days are studied for having prepared the concrete. The results show that the addition of SFEFWT on the concrete containing POFA improves the concrete strengths, particularly the tensile and flexural strengths. The more percentage of SFEFWT content on the POFA concrete results in the higher increase in tensile and flexural strengths. In addition, the presence of SFEFWT contributes to give higher bonding on concrete to control the crack opening on the POFA concrete.

“…The efficiency of tire steel fibers on the compressive strength and freeze-thaw resistance of the conventional plain concrete was reported by Girskas [44]. Also, Dehghanpour et al [45], reported an increase in the compressive strength, flexural strength, toughness, and the absorbed energy under impact loading compared to plain cement mortars.…”

“…Girskas et al [37], concluded that fiber-reinforced concrete is superior in resisting cracks formation, impact loads; therefore, it has high durability, fatigue, and toughness characteristics besides compressive and flexural strengths improvement. Three types of mixtures were manufactured by replacing (1.5%, 3.0%, and 4.5% mass percentages) sand with steel cord scrap that reduced water absorption, open porosity, and increased closed porosity.…”

“…Aggregate in concrete mixes is a natural resource and requires massive mining when producing concrete on an industrial scale. Therefore, it becomes expedient to use other aggregate substitutes, and such research is also being conducted [ 17 , 23 , 24 , 25 , 26 ]. It is possible to reduce the cost of concrete production [ 27 , 28 ] and obtain a material with a modified matrix with specially designed properties [ 9 , 13 , 29 , 30 , 31 , 32 ].…”

This paper discusses an innovative APS hollow block wall with a frame made of concrete modified with recycled materials. The technical data of the hollow block, the percentages of the recycled materials, including SBR rubber granules and PET flakes in the modified concrete, and the composition of the concrete modified with this mixture of recycled additives, are presented. To demonstrate the effectiveness of the solution in reducing mechanical vibrations, the effect of the interaction of different frequencies of the mechanical wave on reducing these vibrations was evaluated for APS blocks and Alpha comparison blocks. The test was carried out on a developed test stand dedicated to dynamic measurements for sixteen frequencies in the range from 8 to 5000 Hz, forcing a sinusoidal course of vibrations. The results are presented graphically and show that the new type of APS hollow block wall was much more effective in reducing mechanical vibrations. This efficiency was in the range from 10 to 51% for 12 out of the tested 16 frequencies. For the frequencies of 8, 16, 128, and 2000 Hz, the values were obtained with a difference of 3.58% in favor of the APS hollow block. In addition, the study of the damping effectiveness of the APS hollow blocks, in relation to the vibrations generated by an M-400 impact mill, showed that the APS block wall had a higher damping efficiency of 16.87% compared to the Alpha hollow block for the signal reading on the floor next to the mill, and 18.68% for the signal reading on the mill body. The modified concrete used in the production of the APS hollow blocks enabled the effective use of two recycled materials, SBR rubber and polyethylene terephthalate, in the form of PET flakes.
