The effect of polypropylene fibers on the properties of fresh and hardened lightweight self-compacting concrete

In this paper, the solution of the nonlinear Troesch’s problem is obtained by means of homotopy perturbation method (HPM). Troesch’s problem arises in the investigation of the confinement of a plasma column by radiation pressure. The results reveal that the homotopy perturbation method (HPM) is very effective, convenient and quite accurate to nonlinear differential equations. It is predicted that the HPM can be found widely applicable in engineering.

Method to Nonlinear Troesch's Problem

Purpose – Self‐compacting concrete (SCC) offers several economic and technical benefits; the use of steel fibers extends its possibilities. Steel fibers bridge cracks, retard their propagation, and improve several characteristics and properties of the SCC. The purpose of this paper is to investigate the effects of type and volume fraction of steel fiber on the compressive strength, split tensile strength, flexural strength and modulus of elasticity of steel fiber reinforced self‐compacting concrete (SFRSCC).Design/methodology/approach – For this purpose, Micro wire and Wave type steel fibers with l/d ratios of 50 were used. Three different fiber volumes were added to concrete mixes at 0.5, 0.75 and 1 per cent by volume of SCC. Six different SFRSCC mixes were prepared. After 28 days of curing, compressive, split and flexural strength and modulus of elasticity were determined.Findings – It was found that, inclusion of steel fibers significantly affect the split tensile and flexural strength of SCC accordanc...

The effect of type and volume fraction (VF) of steel fiber on the mechanical properties of self‐compacting concrete

We apply the homotopy perturbation method and variational iteration method for solving a nonlinear fourth-order boundary value problem. The analytical results of the boundary value problem have been obtained in terms of convergent components with easily computable sentences. This example is given to illustrate the efficiency and implementation of the homotopy perturbation method and variational iteration method. Comparisons are made to confirm the reliability of the methods.
