Experimental Study on Mechanical and Durability Properties of Glass Fiber Recycled Concrete
To study the effect of glass fibers on the basic mechanical properties and durability of recycled concrete,three kinds of fiber length and three kinds of volume admixture of glass fibers were used for the proportion de-sign,and the performance of concrete with different fiber admixture and length was analyzed through the results of compressive strength,tensile strength and chlorine ion penetration resistance tests.The results show that the optimum dosage and length of glass fibers are 0.2％and 6 mm,respectively,when the mechanical properties are the best,and when the length is 12 mm the best resistance to chloride ion permeability;the compressive and ten-sile strength of the recycled concrete increases with the increase of glass fiber dosage,and fiber length has a grea-ter impact on the mechanical strength;and the electrical flux of the recycled concrete decreases with the increase of fiber dosage,which is insignificantly affected by the length.
