The Impact

This study investigated the combine effect of 0.2 % drink cans and steel fibers with volume fractions of 0%, 0.5%, 1%, 1.5%, 2%, 2.5% and 3% to the mechanical properties and impact resistance of concrete. Hooked-end steel fiber with 30 mm and 0.75 mm length and diameter, respectively was selected for this study.  The drinks cans fiber were twisted manually in order to increase friction between fiber and concrete. The results of the experiment showed that the combination of steel fibers and drink cans fibers improved the strength performance of concrete, especially the compressive strength, flexural strength and indirect tensile strength. The results of the experiment showed that the combination of steel fibers and drink cans fibers improved the compressive strength, flexural strength and indirect tensile strength by 2.3, 7, and 2 times as compare to batch 1, respectively. Moreover, the impact resistance of fiber reinforced concrete has increase by 7 times as compared to non-fiber concretes. Moreover, the impact resistance of fiber reinforced concrete consistently gave better results as compared to non-fiber concretes. The fiber reinforced concrete turned more ductile as the dosage of fibers was increased and ductility started to decrease slightly after optimum fiber dosage was reached. It was found that concrete with combination of 2% steel and 0.2% drink cans fibers showed the highest compressive, split tensile, flexural as well as impact strength.

The Impact

This paper studied experimentally the impact mechanical properties of bamboo fiber and hybrid steel fiber reinforced concrete. Steel fiber is already used in construction widely, but it is expensive in cost. As a kind of green building material, bamboo fiber can be used in the infrastructures together with concrete to improve the concretes mechanical properties. In order to investigate the impact mechanical properties of concrete reinforced with bamboo fiber and steel fiber, a series of concrete specimens reinforced with bamboo fiber, steel fiber or both steel fiber and bamboo fiber are investigated with self-designed impact device. The impact resistance abilities are tested and compared.

Research Situation

The current research situation of basalt fiber reinforced concrete was analyzed on the basis of the previous research results. When concrete is incorporated with basalt fiber, the compressive performance of concrete is instable, the tensile strength changes along with the fiber content, but the durability improves significantly , and the bending performance and impact resistance has more obvious improvement. According to the characteristics of chopped basalt fiber reinforced concrete, the prospect of the application of basalt fiber reinforced concrete is explored.
