The invention belongs to the technical field of concrete preparation, and in particular relates to a bubble generation preventing concrete preparation machine. The bubble generation preventing concrete preparation machine comprises a box body, a bottom plate, a cover body, a stirrer, a loading funnel, an air pressure detecting and adjusting system and a control system. A die channel for mounting adie is arranged on the bottom plate, the box body is arranged on the bottom plate, the cover body is movably arranged on the top of the box body, the stirrer is arranged in the box body, a concrete discharge port is formed in the bottom of the stirrer, the loading funnel is arranged below the concrete discharge port and conveys stirred concrete to the die channel on the bottom plate through a hose conveyor to mount the die, the air pressure detecting and adjusting system is mounted in the box body, and the control system is arranged out of the box body. According to the bubble generation preventing concrete preparation machine provided by the invention, concrete stirring and die mounting are carried out in the closed box body, bubbles are prevented from being formed in concrete, deviationon data as a result of insufficient compactness of theconcrete is avoided to a great extent, and the data accuracy and the experimental reliability are improved.
Description
technical field [0001] The invention belongs to the technical field of concrete preparation, and in particular relates to a concrete preparation machine for preventing air bubbles from being produced. Background technique [0002] Concrete is currently the most commonly used material in engineering and occupies an important position in engineering construction. As high-strength concrete is used more and more widely, the strength requirements of concrete are getting higher and higher. In addition to the strength of cement and the concrete water-cement ratio have a greater impact on the strength of concrete, the impact of porosity on the strength of concrete cannot be ignored. The source of the pores is mainly the pores formed by the contact with air during the production process and the ineffective discharge of gas during the subsequent reaction process, resulting in the formation of air bubbles inside the concrete, and the unbroken air bubbles become pores during the subseq...
