Abstract:

Ultra High Strength Steel-Fiber Reinforced Concrete (UHS-SFRC) is characterized by very high compressive and tensile strength that is about 8 times of ordinary concrete, and high ductility owing to the addition of steel fibers. This paper investigates the relationship existing among the direct tensile strength, flexural tensile strength and splitting tensile strength of UHS-SFRC. Differently from ordinary concrete, it is found that the first cracking strengths in UHS-SFRC obtained through direct tensile test and splitting tensile test are similar, while the strength obtained from flexural tens

The deformation of rubberized concrete under uniaxial compression and three-point flexure is studied in this paper by test, and the load-deflection curves and load-strain curves under three-point flexure are obtained. Three rubberized concrete, with 5%, 10% and 15% rubber contents, were tested. The test results show that rubber powder influences the compressive strength and flexural strength of concrete. The greater of the rubber dosage, the greater of the strength decreasing of concrete. The decline of compressive strength is greater than flexural strength, the ratio of flexural strength to c

Abstract One of the tests carried out to determine the quality of ceramic tiles is the flexural strength test (Modulus of Rupture, MOR). So far, the flexural strength test method for ceramic tiles is usually carried out by destructive tests that break the ceramic tiles until they break, which takes a long time and generates ceramic waste. Currently, the use of the non-destructive (NDT) method in the ceramics quality test is growing. The NDT method is a method of testing the quality of solid objects without damaging the object.

The goal of this study was to investigate the influence of cyclic hot and cold water absorption and desorption on the flexural and impact strengths of luffa – PLA biocomposites. PLA was reinforced with heat treated luffa fibers with the fiber loadings: 5 vol.%, 10 vol.%, 15 vol.% and 20 vol.%. Based on the test results the biocomposite with the highest flexural and impact strengths was selected for water absorption and desorption cycles. The biocomposites were subjected to 56 cycles of hot and cold water absorption and desorption. The biocomposites were tested for their strengths after every 1

This study is aimed at evaluating the hybrid reinforcement effects of zirconium oxide nanoparticles (nano-ZrO2) and glass fibers (GFs) at different ratios on the flexural and impact strengths of a polymethylmethacrylate (PMMA) denture base. A total of 160 specimens were fabricated from heat-polymerized acrylic resins using the water bath technique. For the control group, the specimens did not receive any additions; for the test group, different concentrations of nano-ZrO2/GFs at 5% of the PMMA polymer were added. The concentrations of nano-ZrO2/GFs were as follows: 5%–0%, 4%–1%, 3%–2%, 2.5%–2.

This paper proposes a method for the determination of the optimum surfactant amount to achieve the highest strength for carbon nanotubes (CNT) cementitious composites. The method is based on combining the results of a chemical and a mechanical test. The chemical test was used to determine the remaining amount of surfactant after sonication by analyzing solutions containing CNTs, polycarboxylate surfactant, and water. On the other hand, the mechanical test was used to determine the optimum polycarboxylate surfactant amount that achieved the composite’s highest strength by conducting flexural an

Abstract:

The two-dimensional stress distributions in orthotopic composite beam under 4-point flexure are analyzed by replacing the concentrated load by distributing pressure in the vicinity of loading nose and by expanding the stress function for compatability equation in terms of Fourier series. The validity of analytical results is verified experimentally by using the photoelastic film-coating technique on unidirectional reinforced plastics. It is shown that the local stress distributions around the loading points are complicated and are very different from those predicted by elementary beam theory;

In the investigation of mechanical properties, calcium phosphate cements exhibit large sample-to-sample deviation due to its porous nature, possibility of unhomogenous distribution and small specimen size. This situation generates difficulties for obtaining accurate results and creates an obstacle for testing different composition where only a small batch size is available. In this respect, specimen shape, whether being injected, porosity ratio, surface quality, bearing support design have significant matter on variability in terms of three-and four-point bending test.

The present paper investigates flaw strength distributions established using various flexural tests on batches of SiC bar test specimens, namely four-point bending as well as three-point bending tests with different span lengths. Flaw strength is provided by the elemental stress operating on the critical flaw at the fracture of a test specimen. Fracture-inducing flaws and their locations are identified using fractography. A single population of pores was found to dominate the fracture. The construction of diagrams of p-quantile vs. elemental strengths was aimed at assessing the Gaussian nature

When Perfobond Rib shear connectors are used as flexural materials in structures such as bridges, they show flexural shear behavior due to external force, rather than direct shear behavior. The aim of this study is thus to analyze the difference between both behaviors. First, we prepared a specimen to analyze direct shear behavior using Perfobond Rib shear connectors, analyzed the characteristics of behavior with a push-out test and proposed a formula of shear resistance assessment. Proposed formula shows a relatively good fit with less than 10% error. A flexural shear test was then conducted
