  • Publication number: 20250051235
    Abstract: Provided are early-strength and quick-setting ultra-high performance concrete (UHPC), and a preparation method and use thereof. The early-strength and quick-setting UHPC includes, in parts by mass: 110 parts to 180 parts of a red mud, 70 parts to 80 parts of a silica fume, 130 parts to 290 parts of a cement, 400 parts to 500 parts of a quartz sand, 10 parts to 15 parts of a water-reducing agent, 80 parts to 100 parts of water, and 50 parts to 75 parts of a steel fiber. The preparation method includes: subjecting the silica fume, the cement, the quartz sand, and the red mud to first mixing to obtain a first premix; subjecting the first premix, the water, and the water-reducing agent to second mixing to obtain a second premix; and subjecting the second premix and the steel fiber to third mixing to obtain the early-strength and quick-setting UHPC.

  • Patent number: 10675557
    Abstract: The present invention provides a continuous crystallization method under control of the multistage membrane modules, and belongs to the technical field of crystallization engineering. A crystallization solution is added to a crystallizer, and a stirring apparatus and a temperature control apparatus are started. After the system running stability, the loop of crystallization is started. Meanwhile, the coolant or antisolvent feed liquid loop is also started. The crystallization solution can respectively conduct crystal nucleation, growth and ripening in the multistage membrane modules, and then the crystallization solution is transported into a filter device and a drying apparatus to obtain the final crystal products. The desired crystal products can be obtained by the systematical control of the nucleation and crystal growth through the flow and the temperature of the crystallization solution, coolant or antisolvent feed liquid, and the contact time between two liquid phases.

  • Patent number: 8928734
    Abstract: A method and a related system of free-view relighting for a dynamic scene based on photometric stereo, the method including the steps of: 1) performing multi-view dynamic videos of an object using a multi-view camera array under a predetermined controllable varying illumination; 2) obtaining a three-dimensional shape model and surface reflectance peculiarities of the object; 3) obtaining a static relighted three-dimensional model of the object and a three-dimensional trajectory of the object; 4) obtaining a dynamic relighted three-dimensional model; and 5) performing a free-view dependent rendering to the dynamic relighted three-dimensional model of the object.

  • Patent number: 8813576
    Abstract: A new type of coriolis mass flow meter is disclosed. In one embodiment, the coriolis mass flow meter comprises two or more flow splitters, each flow splitter being connected to two or more flow tubes; and one or more supporting pipes connecting the flow splitters. The one or more of the flow splitters have a smooth round corner with a 65° turning angle. The distance between the centers of the two or more splitter tubes is about 1.1 to 1.2 times dT, where dT is the inner diameter of each splitter tube. The splitting turning radius RT is about 1 to 2.5 times DN; where DN is inner diameter of the flange portion of the flow splitter. The inner diameter of each splitter tube is about 0.8 to 0.85 times DN/?2.
