tailoring engineered cementitious composites for Impact Resistance
Cement and Concrete Research, 2012Co-Authors: En-hua Yang, Victor C LiAbstract:This paper presents results of deliberate tailoring of engineered cementitious composites (ECC) for Impact Resistance. Microstructure control involving fiber, matrix and fiber/matrix interface was based on steady-state dynamic crack growth analyses accounting for rate dependence of composite phases. Uniaxial tensile stress-strain curves of the resulting Impact resistant ECC were experimentally determined for strain rates ranging from 10{sup -5} s{sup -1} to 10{sup -1} s{sup -1}. Low speed drop weight tower test on ECC panels and beams was also conducted. Damage characteristics, load and energy dissipation capacities, and response to repeated Impacts, were studied.

Microstructure control involving fiber, matrix and fiber/matrix interface was based on steady-state dynamic crack growth analyses accounting for rate dependence of composite phases. Uniaxial tensile stress-strain curves of the resulting Impact resistant ECC were experimentally determined for strain rates ranging from 10 - 5 s- 1 to 10- 1 s- 1. Low speed drop weight tower test on ECC panels and beams was also conducted. Damage characteristics, load and energy dissipation capacities, and response to repeated Impacts, were studied. © 2012 Elsevier Ltd. All rights reserved.

the Impact Resistance and mechanical properties of reinforced self compacting concrete with recycled glass fibre reinforced polymers
Journal of Cleaner Production, 2016Co-Authors: Mohammad Mastali, A Dalvand, A R SattarifardAbstract:Abstract Experimental and statistical analyses are represented considering the Impact Resistance and mechanical properties of self-compacting concrete reinforced with recycled Glass Fibre Reinforced Polymers (GFRP). Specimens were reinforced with recycled GFRP in three groups, including 0.25%, 0.75%, and 1.25% of fibre volume fractions. An extensive experimental program including two hundred and fifty two specimens were prepared and tested to characterize the Impact Resistance and mechanical properties of the reinforced self-compacting concrete with glass fibre reinforced polymers. Scanning Electron Microscope images were used to perceive the failure mechanism of recycled glass fibre in the matrix. Then, the relatively large and reliable collected data from the experimental tests was used to start statistical and analytical analysis. The results showed that adding recycled glass fibre reinforced polymers results in improving the Impact Resistance and mechanical properties of the reinforced self-compacting concrete with glass fibre reinforced polymers. Moreover, the statistical data analysis revealed that the Impact Resistance and mechanical properties of reinforced self-compacting concrete follow a normal distribution. Furthermore, some equations were developed to correlate the Impact Resistance of the reinforced self-compacting specimens to the mechanical properties with high values of coefficient of determination.

Statistical Evaluation for Impact Resistance of Steel Fiber Reinforced Lightweight Aggregate Concrete
Advanced Materials Research, 2011Co-Authors: Hong Wei Song, Hai Tao WangAbstract:The Impact Resistance of steel fiber reinforced lightweight aggregate concrete was presented in a drop weight test. In this test, 5 groups of disc specimens with different steel fiber volumes including 0.0%, 0.5%, 1.0%, 1.5% and 2.0% were tested. The experimental results indicated that the Impact Resistance of lightweight aggregate concrete is improved with the increase in fiber volume. As the variation in experimental results, a statistical evaluation was performed to study the influence of Impact Resistance of steel fiber reinforced lightweight aggregate concrete with different steel fiber volumes. Further more, the Impact Resistance was simulated with probability distribution by Log-normal method. And the goodnees-of-fit tests indicate that the Log-normal method has good fitness to the Impact Resistance of steel fiber reinforced lightweight aggregate concrete.
