The invention discloses a device for measuring free bleeding rate and free expansion rate of grouting slurry comprising a test container, a fixed ruler, a movable ruler, a sealing cover and a balanceplate; the test container is detachably arranged on the surface of the balance plate, the sealing cover is detachably arranged at the upper end of the test container, the fixed ruler is arranged perpendicular to the surface of the balance plate, and the movable ruler is arranged on the ruler body of the fixed ruler in a sliding mode. According to the device for measuring free bleeding rate and free expansion rate of grouting slurry provided by the invention, a fixed ruler which is arranged in parallel with the test container and a movable ruler which slides on the fixed ruler are arranged outside the test container, so that the change of the upper surface of the grouting slurry measured and read in the test process is more accurate, and the test precision is greatly improved; meanwhile, the measuring device is simple in structure, low in preparation cost and high in operability.
