Abstract
A study on mechanical properties of polyolefin and glass fiber reinforced concrete.

This study is intended to apply high strength fiber reinforced concrete to the area such as Small-scale reinforced concrete structure adjacent to the vertical member and the floor slab, etc which do not require high strength.
In order to improve the tensile strength of concrete, we have compared and analyzed the mechanical properties of the fiber reinforced concrete according to the fiber mixing ratio through experiments. We have following conclusions.
The fluidity in the fiber mixing amount is found to be dramatically reduced regardless of the type of fiber. The reduction of SF is greater than that of FG.
SF and FG have improved performance in compressive strength, tensile strength and bending strength when the fiber mixing amount is increased.
The compressive strength of SF grows with increasing of the fiber mixing amount. FG has the maximum values when the fiber mixing amount is 5kg/㎥ however it decreases when mixed more
The tensile strength of SF increases to 208% when the fiber mixing amount is 15 kg/㎥ In case of FG, It increases to 161% when the fiber mixing amount is 15 kg/㎥ However the effect is not significant when mixed over SF is more effective than FG in improvement of tensile strength.
SF represents 175% increase in bending strength improvement when the fiber mixing amount is 5kg/㎥ but slightly decreases when mixed over.
It can be seen that bending strength increases with the fiber mixing amount. The performance improvement of bending strength is similar to SF and FG.
