“…Al-Naimi and Abbas [31] confirmed that the addition of steel fibers contributes to increased toughness in the post-crack phase. A similar effect was observed with the use of basalt [27,32] and polypropylene fibers [33,34]. It has been observed that steel fibers more significantly contribute to increasing the toughness of concrete than PP fibers [34].…”

Because of the increasing use of lightweight aggregate concrete as a construction material, the paper gives its classification, as well as a brief summary of its advantages and disadvantages in relation to a normal weight concrete. The addition of fibers has proved efficient at improving the properties of lightweight aggregate concrete, especially in terms of correcting its brittle behavior in tension and bending. Based on the literature review, the influence of the type and amount of fibers on the properties of fresh and hardened lightweight aggregate concrete is presented.

“…Nagarajan et al used basalt ber up to 0.25% in lightweight concretes. Sorptivity coe cients of concretes increased with the increase in basalt ber ratio (Nagarajan et al 2020). Basalt ber was used up to 0.20% by volume in the study conducted by Niu et al As the basalt ber ratio increased, the water penetration depth of the concretes increased (Niu et al 2020).…”

In this study, the use of copper slag and aggregate together with basalt fiber in cement-based composites was studied. It was aimed to contribute to the ecosystem by using copper waste, which is an environmental problem, in cement-based composites. In addition, the effect of basalt fiber on the strength and durability properties of composites was investigated. Taguchi optimization was carried out for cement-based composites. In this context, Taguchi L18 matrix was used. Copper slag was used at rates of 0, 7.5% and 15%, and copper aggregate at rates of 0, 25% and 50%. Basalt fibers of 6 and 12 mm length were used at the rates of 1%, 2% and 3%. The w/b ratios of the mixtures were chosen as 0.40, 0.50 and 0.60. Durability tests such as permeability, freeze-thaw and sulphate resistance with fresh and hardened mortar properties were performed on 18 different mixtures. In terms of the 7, 28 and 91-day flexural and compressive strength of the mixtures, the use of 1% of 6 mm long fiber in the mixtures with a w/b ratio of 0.40 provided more positive results. In terms of freeze-thaw resistance, it is necessary to use 3% of 6 mm long fiber in mixtures with 0.40 w/b. The use of 7.5% copper slag reduced the water penetration depth. The use of 15% copper slag in mixtures affected by sodium sulphate reduced the expansion values. Since the increase in the ratio of copper aggregate decreased the aggregate volume, it caused the drying shrinkage values to increase. As a result, it was observed that copper slag has a more positive effect than copper aggregate for the strength and durability of composites. However, by using 25% of copper aggregate by sacrificing some features, it can contribute to the environment and ecosystem. The use of basalt fiber with a length of 6 mm and a ratio of 1% increased the mechanical properties, while the use of 3% contributed significantly to the freeze-thaw resistance. It was determined that copper wastes contribute to the environment and ecosystem by using them instead of cement and aggregate.

“…Sintered fly ash aggregate concrete (SFAC) was more suitable for the structures exposed to sulphate and chloride environments . Hasan & Turan, 2013;Ranjith & Thenmozhi, 2018 has carried out a work on concrete produced with 40% (by weight) partial replacement of fly ash aggregates with granite aggregates possess an increase in workability and doesn't show any segregation (Divyah,Thenmozhi,Neelamegam & Prakash, 2020). Jiangpeng, et al (2017) used finite element analysis to know the failure propagation of concrete and steel yielding in the reinforced concrete slabs to know the punching shear force.…”

This paper presents experimental and numerical investigations on M30 Grade of concrete containing 40% of sintered fly ash aggregates (SFAs) on the punching behaviour of reinforced concrete (RC) slabs. Two 1000 x 1000 x 100 mm reinforced concrete slabs were cast and subjected to punching tests. The experimental results were compared with creating a nonlinear finite element programme using ABAQUS. This 3D Finite element analyses were performed with the appropriate modelling of element size and the constitutive modelling of concrete. The material parameters of the damaged plasticity model in ABAQUS were calibrated based on the test results of slab – plate connection. The comparison between experimental and numerical results indicates that the calibrated model correctly predicts the punching shear response of the slabs. A modification of 0.4 is introduced in MC2010 code.
