“…The results of ultrasonic velocity measurements represented by calculated velocity variation coefficient are summarized in Table 2. The specimen with 5.0% of fibres did not achieve satisfactory homogeneity (Δ = 8.4%), due to insufficient fibre amount for creation the uniform skeleton, which corresponds with the findings published in study [10]. All the other specimens showed very good homogeneity-regardless of the measuring point, the ultrasonic velocities of these specimens remain almost constant, with Δ lower than 5%.…”

“…As the traditional concrete technology is difficult to be adopted when using not classified waste fibres (the fibres tend to stay in bulks and the proper disintegration and homogenous dispersion is difficult to achieve in higher fiber dosage), the slurry infiltration technology was tested in this study. Slurry infiltrated fibre concrete -SIFCON was first developed in 1979 in USA, by incorporating large amounts of steel fibres in cement-based composites [10]. SIFCON is prepared by infiltrating pre-placed fibres with fine grain aggregate mortar.…”

“…This limits the fibre volume V f to 1 -5%, depending on the type of fibre used and the required workability of the mixture. SIFCON specimens can be produced with V f between 5% and 30% [10], the fibre volume depends on the fibre geometry, length and diameter and vibration of the fibres during their placement process. SIFCON possesses excellent mechanical propertiesextraordinary behaviour in flexure and punching shear coupled with very good energy-absorption characteristics [11,12].…”

Abstract. The utilization of waste steel fibres (coming from the recycling process of the old tires) in production of blast resistant cement based panels was assessed. Waste fibres were incorporated in slurry infiltrated fibre concrete (SIFCON), which is a special type of ultra-highperformance fibre reinforced concrete with high fibre content. The technological feasibility (i.e. suitability of the waste fibres for SIFCON technology) was assessed using homogeneity test. Test specimens were prepared with three volume fractions (5; 7.5 and 10 % by vol.) of waste unclassified fibres. SIFCON with industrial steel fibres (10% by vol.) and ultra-highperformance fibre concrete with industrial fibres were also cast and tested for comparison purposes. Quasi-static mechanical properties were determined. Real blast tests were performed on the slab specimens (500x500x40 mm) according to the modified methodology M-T0-VTU0 10/09. Damage of the slab, the change of the ultrasound wave velocity propagation in the slab specimen before and after the blast load in certain measurement points, the weight of fragments and their damage potential were evaluated and compared. Realized tests confirmed the possibility of using the waste fibres for SIFCON technology. The obtained results indicate, that the usage of waste fibres does not significantly reduce the values of SIFCON flexural and compressive strength at quasi-static load -the values were comparable to the specimens with industrially produced fibres. With increasing fibre content, the mechanical parameters are increasing as well. Using of the waste fibres reduces fragmentation of SIFCON at blast load due to the fibre size parameters. Using of low diameter fibres means more fibres in the matrix and thus better homogeneity of the whole composite with less unreinforced areas. Regarding the blast tests, the specimen with waste steel fibres showed the best resistance and outperformed also the specimen with commercial fibres. Using of waste fibres in SIFCON technology can reduce the price of this composite by 70 % by keeping the original SIFCON extraordinary properties, which makes it very competitive material in the concrete area.

The growing importance of environmental efficiency in reducing carbon emissions has prompted scientists around the world to intensify their efforts to prevent the destructive effects of a changing climate and a warming planet. Global carbon emissions rose by more than 40% in 2021, leading to significant variations in the planet’s weather patterns. Nevertheless, a significant proportion of natural resources continue to be exploited. To prepare for this challenge, it is essential to implement a sustainable approach in the construction industry. Biobased materials are made primarily from renewable raw materials like hemp, straw, miscanthus, and jute. These new materials provide excellent thermal and acoustic performance and make optimum use of local natural resources such as agricultural waste. Nowadays, cement is one of the most important construction materials. In an attempt to meet this exciting challenge, biobased materials with low-carbon binders are one of the proposed solutions to create a more insulating and less polluting material. The aim of this review is to investigate and to analyze the impact of the incorporation of different types of biobased materials on the mechanical, thermal, and hygric performance of a mix using different types of binder.
