“…Promising results have been obtained as regards the vibration damping coefficient in concrete composites modified by polymers and kinescope glass [45]. In [50][51][52], concrete samples containing different proportions of sand and waste red ceramic aggregate (RWCA) were tested. Among other things, compression and bending samples were tested, crack resistance and fatigue properties were determined.…”

The article presents results obtained during testing of concrete based on CEM I 42.5R Portland cement, fine and coarse aggregate, glass, volatile ash, and superplastifier. The concrete mixture was modified using filler consisting of bromosilicate heat resistant cullet. Recycled aggregate was added to the batch. Samples for the need of testing were produced as (100 × 100 × 100) mm cubes. Before commencing proper tests, samples have been heated within the temperature range of 20–800 °C. Tests carried out during the proper testing procedure included tests of compressive strength, elevated temperature, impact strength, as well as macroscopic tests of the contact area. The obtained test results have provided proof of there being a possibility of producing special concrete, modified by products obtained from heat resistant cullet. This type of is generally characterized by satisfactory performance parameters. The average compressive strength for concrete modified by a 10% of heat resistant cullet was determined as 43.6 MPa and 48.3 MPa respectively after 28 and 180 days of curing.

“…The aggregates counterparts are those having high crushing strength and moderate water absorption properties, such as steel slag, ceramics, recycled aggregate and palm kernel shell [6][7][8][9][10][11][12]. Also, numerous reports have shown that steel fibre possesses tensile properties suitable for improving the performance of SCC [13][14][15][16][17]. Particularly, the macro-hooked ends steel fibre with multiple hooks exhibited strong impact on strength of SCC as discussed in [18].…”

Self-compacting concrete (SCC) production is growing rapidly due to its several advantages in terms of enhanced properties and applications. However, there are associated sustainability issues with the SCC materials. With the demand for SCC expected to continually increase, an ideal solution is therefore required to sustain the technology, such as derivation of alternative materials. Thus, this study explores innovative application of industrial wastes in self-compacting concrete production, with the aim of finding the most appropriate technique in SCC material use. Also, the potential limitations in using some of the waste materials as sustainable alternatives were highlighted. This study found that several materials emanating from industrial rejects have been mostly investigated as a potential material for making SCC, which showed that the incorporation of waste materials into SCC could be a viable approach. However, in order to achieve optimal performance of SCC, an adequate material composition is necessary. It is clear from this study that factors such as embodied carbon, energy and cost of SCC production can notably be reduced with the incorporation of waste materials. The study also identified areas for further investigations that can help in the improvement of SCC for construction applications.

“…These include crimped, straight, spiral, hooked end and twisted [16,17]. However, according to the last statistics, two thirds of steel fibres used in concrete are hooked end fibres of single hooked (3D) compared with other types [18,19].…”

A series of uniaxial tensile tests on cylinders made from steel fibre reinforced selfcompacting concrete (SFR-SCC) have been carried out to investigate the influence of fibre geometry and the combined effect of fibre content and distribution on the post-cracking behaviour. Three types of commercially available hooked end fibres (3D (single hooked), 4D double (double hooked) and 5D (triple hooked)) have been used in this study, which are added to the concrete mixture at two fibre dosages (0.5 and 1% by volume). The experiments show that the post-cracking strength increases significantly (P˂ 0.05) with the increase of fibre content for all mixtures. The combination of a unique shaped hook of high tensile strength demonstrates an optimum effect on the failure mode of concrete cylinders in which peak and post-peak strengths are raised. Notably, strain-hardening behaviour is observed only for cylinders reinforced with 5D hooked end fibres. A correlation between number of fibres exposed on fractured surfaces and post-cracking behaviour is established.
