“…When SF, FA, and/or NS were added to the mixtures of SCC, a higher compressive strength was obtained. This finding was due to the enhancement of the C–S–H gel present in the cement paste 76,77 and the appropriate distribution of C–S–H, which gave the hardened SCC a stronger microstructure 78–80 . Furthermore, the shifting size of the voids present between the cement grains could increase the packing density and densify the microstructure 81,82 .…”

This research focused on finding the effect of nanosilica (NS) on the properties of self‐compacting concrete (SCC). NS in various proportions of 1%, 2%, 3%, 4%, 5%, 6%, 8%, and 10% was added to SCC with 10% silica fume (SF) or 10% fly ash (FA) by weight of cement to improve the properties of SCC. While the limestone powder (LSP) was used at a fixed supplementation of 15% by cement weight for all mixes. Fifteen SCC mixtures were designed based on the European guidelines for self‐compacting concrete. The properties of fresh SCC were evaluated by several tests of the slump flow, slump T50, V‐funnel, V‐funnel T5min, L‐box J‐ring, and fill box. Meanwhile, several tests evaluated SCC's mechanical properties, including compressive strength, split tensile strength, flexural strength, bond strength, and modulus of elasticity. Moreover, the permeability properties of SCC were evaluated by water permeability and air‐content tests. The effect of applying high temperatures (100–800°C) on the compressive strength of SCC containing NS with cementitious materials (SF, FA, and LSP) was also evaluated. Results showed that adding 3% NS with 10% SF and 15% LSP by weight of cement can be used to achieve the best mechanical properties of SCC. The SFNS3 mixture achieved the highest mechanical properties of 75.1, 11.9, and 41,300 MPa for compressive strength, bond strength, and modulus of elasticity tests. While the results for the slump flow, slump T50cm, and fill box were 680 mm, 6 s, and 93%.

“…Smaller TRE thicknesses had smoother load-slip curves and greater interfacial fracture energy at different rates during dry-wet cycles. Fattouh et al (2023) [17] found in his research that adding steel fiber or steel fiber with silica fume to concrete improves compressive strength and flexural behavior, with the strongest results seen in tap watercured concrete. Compressive strength increased by 23-25% from 7 to 28 days for tap water-cured concrete and 23-26% for SW-cured concrete.…”

“…Typically, the properties monitored are those most of which are known for ordinary concretes, such as compressive strength, modulus of elasticity or consistency. In addition, other properties are usually monitored, such as the amount and distribution of the fibres, and flexural tensile strength, ductility, toughness and residual flexural strength of SFRC [5,6,7]. Unfortunately, there are very few articles dealing with…”

The paper focuses on the consistency of fresh steel fibre reinforced concrete in relation to the amount of steel fibre used. Consistency was determined by the slump test and the flow table test. Furthermore, the paper deals with monitoring the compressive strength and volume changes during the maturing process of steel fibre reinforced concrete. Volume changes were monitored using a shrinkage drain. The results of the steel fibre reinforced concrete properties are compared with the values of the reference concrete without fibres and with each other. The result is an evaluation of how the amount of fibre affects the properties of fresh and hardened concrete. The dependence between consistency, compressive strength and shrinkage of steel fibre reinforced concrete is also established.
