Problems solved by technology

[0004] In the preparation process of self-leveling concrete slurry in the prior art, each component is put in in batches, and the stacking of different raw materials affects the uniformity of mixing and stirring efficiency, which reduces the speed of preparation, and the coal ash and mineral powder in it are mixed with cement. Poor mixing uniformity reduces slurry production quality

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a preparation device for self-leveling concrete castables. Background technique [0002] Concrete is one of the most important civil engineering materials in contemporary building materials. It has many advantages: abundant raw materials, low price, simple production process, high compressive strength and good durability. However, in ordinary concrete, the porosity of the interface area is higher than that of cement stone, and the pore structure formed by micro-bleeding due to vibration, the accumulation of air bubbles and the local water-cement ratio in the interface area are more serious; in addition, When the slump of conventional concrete exceeds 12cm, it is easy to cause concrete segregation. [0003] Self-leveling concrete can produce fresh concrete that can be easily pumped, does not require vibratory operations for leveling and does not cause segregation, and can produc...
