“…Steel fiber is a very effective material for dispersed reinforcement in rigid concrete pavements. In a previous study by Latifa [10], due to the use of a reasonable amount of steel fiber, the compressive strength, flexural strength, and Young modulus of concrete were significantly increased. In another study [11], the use of steel fiber with a proportion of 8% by cement weight led to an increase in the compressive strength of rigid pavement concrete by up to 45% and flexural strength by up to 60%.…”

The complex effect of the amount of cement, polypropylene fiber (the fiber length was 39 mm, and the diameter was 0.45 mm), and polycarboxylate superplasticizer on concrete properties for rigid pavement was determined using the methods of experiment planning and experimental–statistical modeling. The fluidity of all the mixtures was S1. The W/C of the mixtures depended on the composition of the concrete and variable from 0.32 to 0.46. It was found that, by increasing the amount of superplasticizer from 1% to 1.8–2%, the compressive strength of concrete increased by 4.5–6 MPa after 3 days and by 7–9 MPa after 28 days. The flexural strength in this case increased by 0.6–0.9 MPa. The use of polypropylene fiber in the amount of 1.5–1.8 kg/m3 increased the compressive strength of concrete by an average of 3 MPa, increased the flexural strength by 0.5–0.6 MPa, reduced the abrasion capacity by 9–14%, and increased the frost resistance by up to 50 cycles. When using a rational amount of superplasticizer and fiber, the compressive strength of concrete, even with a minimum cement amount of 350 kg/m3, was at least 65 MPa, its flexural strength was at least 6 MPa, its frost resistance was F200, and its abrasion capacity was not more than 0.30 g/cm2. Concrete with such properties can be used for roadways of any type. Low abrasion capacity and high frost resistance provide the necessary durability of concrete for rigid pavement during operation.

“…Only two Technical Standards address the theme: (a) NBR 15530 "Steel fibers for concretespecification" [5]; and (b) NBR 8890 "Circular section concrete pipe for rainwater and sanitary sewerage systems -Requirements and test methods" [6]. Despite this national reality, in other countries this material already has great applicability in Structural Engineering, for example, in shotcrete for tunnels, earthquakes regions, slender repairs, pavements subjected to dynamic loads, in the area of structural recovery, rigid pavements subjected to cyclic loads [7]- [11] including technical standards which guide tests and design steps, such as the following codes: ACI 544.1R-96 [12], ACI 544.2R-89 [13], ACI 544.3R-93 [14], ACI 544.4R-88 [15], ACI 318 [16], RILEM TC 162-TDF [17], Model Code 2010 [18] and EN 14651 [19]. The study of this material is still an open research field, especially concerning the computational modelling line of structural parts composed of this material.…”

This work deals with parametric analyses of the structural behaviour of steel-fiber-reinforced concrete using a Damage Constitutive Model and homogenization technique. This approach is contemporary once Brazil has not a standard procedure for the design of this type of material. The present study performs a parametric analysis of rectangular beams subjected to flexion at four points, with height variations (h), reinforcement area (As) and span (L) are used to verify the influence of each parameter on the numerical study of the deformability of beams composed by this material. Fiber volume concentrations of 2.00% and 2.50% have been used on the modelling. It is observed that the obtained results were mainly affected by height and span. It is noticeable that the inclusion of steel fibers leads to an increase in the maximum load and ductility of the analyzed beams in this work.

During the last three decades, concrete pavement or rigid pavement became a widely used alternative of flexible pavement (asphalt pavement) at freeways and highways with high traffic of heavy vehicles, due to its durability, long life, and less need of maintenance; however, the cost of construction for rigid pavement is very high compared to asphalt pavement. Developing a new concrete mixture to increase the performance and reducing the required thickness of concrete pavement became an important issue in rigid pavement design in order to reduce the high construction cost. In this study, a new concrete mixture was developed using specific amounts of steel fibers and steel slag (as a supplementary cementing material to replace a part of the cement). Several mixtures with different concentrations of fibers were prepared, and samples were tested for workability, early flexural strength, and ultimate flexural strength. The results showed that the new concrete mixture could achieve an increase in flexural strength between 48.9% and 50.5% compared to normal concrete mixture without steel fibers and steel slag, with minimum acceptable workability, and therefore, the required pavement thickness could be decreased by more than 24%.
