“…The modulus of elasticity of concrete (E c ) is a material property that describes the deformation parameters and geometric response of a structure when loaded [40]. It is a function of the stress-strain behavior of its constituent material and represents an essential property in the analysis and design of structural elements [41].…”

Abstract:Concrete is a very popular material in the construction industry-it is, however, susceptible to quasi-brittle failure and restricted energy absorption after yielding. The incorporation of short discrete fibers has shown great promise in addressing these shortfalls. A natural fiber such as sisal is renewable, cheap, and easily available. It has also exhibited good tensile strength and can significantly improve the performance of concrete. In this study, the physical and mechanical properties of sisal fiber-reinforced concrete were reported. Sisal fibers were added in the mix at percentages of 0.5%, 1.0%, 1.5%, and 2.0% by weight of cement. Physical properties measured are workability, water absorption, and density while mechanical properties reported are compression strength, split tensile strength, and static modulus of elasticity. The computed modulus of elasticity of sisal fiber-reinforced concrete was compared with predicted values in some common design codes. From the study, it was concluded that sisal fiber can enhance the split tensile strength and Young's modulus of concrete but cannot improve its workability, water absorption, and compressive strength.

“…The elastic modulus of the concrete in compression and tension from the experimental results by [5] are very much different therefore making the concrete model to possess anisotropic behaviour and could also lead to instability of the model since the model in this study is created as isotropic model. This is also supported by [9] that when the elasticity modulus of concrete and fibre-reinforced concrete in compression and tension vary from each other, the widely used equality assumption of both values may have a negative effect on structural behaviour analysis and experimental evaluation. So, it cannot be assumed that the modulus of elasticity of the concrete in compression and in tension is the same to be used in the numerical analysis.…”

This paper presents the study on the numerical analysis of splitting tensile strength test of steel fibre reinforced concrete under static loading. ABAQUS FEM software is used to model the test configuration for plain concrete and steel fibre reinforced concrete (SFRC) based on the experimental investigations that studied the effectiveness of adding steel fibres of 1.5% volume fraction into the concrete mix. Four 3D models are created which are brick concrete, brick SFRC, stone concrete and stone SFRC. The numerical analysis results are compared with the published experimental results in terms of splitting tensile strength, tensile stress-strain relationship and tensile damage. The splitting tensile strengths from horizontal stress output are found to be slightly lower compared to the experimental results with percentage difference of less than 15%. While the results from using analytical formula also underestimate the splitting tensile strength with percentage difference up to 22% when compared to the experimental results. Elastic modulus from tensile experimental results should be taken as Young’s modulus of the model since it gives results that are closer to experimental results. The Poisson’s ratio that gives the closest results to the experimental result is taken as the Poisson’s ratio of the concrete and SFRC. The adopted 3D model captured reasonably well the reaction of the concrete cylinders subjected to splitting tensile test. Numerical analysis displays a strong correlation with the experimental results after proper evaluations and realistic optimizations of the governing parameters through extensive analyses.

“…As (drying) shrinkage was not measured for S100, it is recommended to include shrinkage measurements in future studies. The elastic tensile moduli and the ratios are indirectly determined, and are significantly lower compared to experimentally reported values for conventional concrete by Tipka et al [50]. To verify the obtained results and the adopted bi-modular approach, the tensile elastic modulus of AACs should be measured in the future.…”

“…Consequently, the elastic compressive modulus (E c ) and elastic tensile modulus (E t ) are assumed to be equal. This is a reasonable assumption given that the ratio between the elastic tensile modulus and the elastic compressive modulus for OPCCs is around 0.9 [50]. However, it is not clear if the same ratio and accompanying assumptions are valid for AACs.…”
