APPARATUS FOR ESTIMATING PUMPABILITY OF CONCRETE

摘要

PURPOSE: A pumpability inspecting device of concrete is provided to perform the efficient quality control of concrete by estimating the friction force of compressing transferring pipe. CONSTITUTION: A pumpability inspecting device of concrete comprises a frame(10), a force pipe(20), a support part, a lifting part(40), a driving part(50) and a controller(60). The force pipe is formed in the form having open upper and lower parts in order to fill concrete in a synthetic resin conduit of transparent material or opaque material. The bonding groove is formed on the external periphery of the lower end of the force pipe. The support part perpendicularly clinches the force pipe on the frame and combined with the bonding groove of the force pipe. The lifting part raises the concrete charged inside the force pipe.
