Abstract: The treated rape straw fiber was cut into 4 lengths of 10-15 mm, ＞15-20 mm, ＞20-25 mm and ＞25-30 mm, and mixed into the rape straw fiber concrete with the volume content of 0.2%, 0.4%, 0.6% and 0.8% for each fiber length respectively, which were used to carry out the freeze-thaw cycle test. The apparent morphology of the rape straw fiber reinforced concrete was observed for 25, 50, 75 and 100 freeze-thaw cycles, and its mass and dynamic elastic modulus were measured. The effects of the length an... More
