Fire-resistance property of reinforced lightweight Aggregate Concrete wall
Construction and Building Materials, 2012Co-Authors: C.g. Go, Jun-ren Tang, Cheng-tung Chen, Yue-lin HuangAbstract:Abstract This research focuses on reinforced lightweight Aggregate Concrete walls. After performing a standard temperature rising fire-resistance test, the fire resistance performance and mechanic behavior of the wall sample are studied under a lateral horizontal load. Reinforced lightweight Aggregate Concrete walls and reinforced normalweight Concrete walls are given the fire-resistance test under the same conditions, then their fire resistance performance and mechanical behaviors are compared. Taking into consideration the steel spacing, Aggregate type, wall size, and high temperature as the wall sample variables. The research results showed that the reinforced lightweight Aggregate Concrete wall is superior to the reinforced normalweight Concrete wall on ultimate load, yield load, cracked load, stiffness, ductility, and inter-story drift after a high-temperature fire-resistance test. In terms of failure patterns, for a reinforced lightweight Aggregate Concrete wall after a high-temperature fire-resistance test, the smaller the steel spacing the higher the yield load and ultimate load, but the worse the ductility. This result matched the results of the reinforced lightweight Aggregate Concrete wall without the high-temperature fire-resistance test and revealed that the reinforced lightweight Aggregate Concrete wall retained its mechanics after the fire-resistance test.

Shear behavior of three types of recycled Aggregate Concrete
Construction and Building Materials, 2019Co-Authors: Bing Liu, Chao Feng, Zhiheng DengAbstract:Abstract This paper studied the shear behavior of three types of recycled Aggregate Concrete with different replacement levels of recycled coarse Aggregate. Sixty cube specimens and thirty beam specimens with uniform depth and varying width were designed to test their mechanical parameters including cube compressive strength, splitting tensile strength, shear strength, peak shear strain, shear stress-strain curves, and shear modulus. We analyzed how these parameters are influenced by the type of recycled coarse Aggregate and by recycled coarse Aggregate replacement level. We established the strength conversion equations, one-parameter polynomial non-dimensional shear stress-strain equations, and shear modulus calculation formulas of three types of recycled Aggregate Concrete. It is found that the strength of recycled Aggregate Concrete I isslightly lower than that of conventional Concrete and decrease with the increase of recycled coarse Aggregate replacement level. However, the strength of recycled Aggregate Concrete II and recycled Aggregate Concrete III is slightly higher than that of conventional Concrete when the recycled coarse Aggregate replacement ratio is less than 70%. As the recycled coarse Aggregate replacement ratio increase, the peak shear strain of three types of recycled Aggregate Concrete gradually decreases. The shear strength and peak scant shear modulus of three types of recycled Aggregate Concrete show the rule of recycled Aggregate Concrete III > recycled Aggregate Concrete II > recycled Aggregate Concrete I. Furthermore, the calculated values of several equations established by the authors agree well with the test values.

axial stress strain behavior of macro synthetic fiber reinforced recycled Aggregate Concrete
Cement & Concrete Composites, 2019Co-Authors: Syed Minhaj Saleem Kazmi, Muhammad Junaid Munir, Indubhushan Patnaikuni, Yingwu Zhou, Feng XingAbstract:Abstract This study aims to investigate the axial stress-strain behavior of macro-synthetic fiber reinforced recycled Aggregate Concrete. Concrete cylinders reinforced with macro-synthetic fibers were tested under axial compression, with the variation of three different replacement ratios of recycled Aggregates (i.e., 0, 50 and 100%) and three different dosages of macro polypropylene fibers (i.e., 0, 0.5 and 1% of volume of recycled Aggregate Concrete). A comparative study of the existing stress-strain models for steel fiber reinforced normal and recycled Aggregate Concrete with the test results indicates that the stress-strain behavior of steel fiber reinforced normal and recycled Aggregate Concrete can be well predicted by these existing models. No stress-strain model for macro-synthetic fiber reinforced normal and recycled Aggregate Concrete has been developed. Based on the test results, a stress-strain model is developed in this work by modifying the parameters of best performing stress-strain model for steel fiber reinforced normal Aggregate Concrete. The proposed model can effectively predict the stress-strain behavior of both steel and macro-synthetic fiber reinforced normal and recycled Aggregate Concrete. Test results show that the peak stress, peak strain and ultimate strain of Concrete specimens increase with the increase in fiber dosage and the addition of fibers has a better effect on recycled Aggregate Concrete and as compared to normal Aggregate Concrete.
