Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete processing, in particular to a continuous feeding and storage device for concrete synergist. Background Technique
[0002] Concrete is an artificial building material prepared by mixing cementitious materials, granular aggregates (also known as aggregates), water, and concrete admixtures in a certain proportion, and then uniformly stirred, densely formed, constructed and cured, and finally hardened; it has the characteristics of rich raw materials, low price, and simple production process, and is one of the most important civil engineering materials in modern times; at the same time, concrete also has the characteristics of strong plasticity, high compressive strength, and good durability; these characteristics make its application range very wide, and it is not only used in various civil engineering projects, but also an important basic construction material in the fields of shipbuilding, mechanical industry, ocean development, geothermal engineering, etc. Research shows that due to the precipitation of hydration products on the surface of unhydrated hydration particles, inhibiting the hydration of cement, nearly 20% of the cement in the hardened cement paste ultimately cannot be hydrated normally and only plays a filling role; this not only causes waste of cementitious materials, but also leads to the inability of cement to fully exert its strength. Adding a concrete synergist with a strong dispersing effect on cement particles during the concrete mixing process can improve the dispersion degree of cement particles and mineral fine aggregates, make the cement particles contact with water more fully, further improve the hydration degree of cement particles, and thus improve the mechanical and durable properties of hardened concrete. Correspondingly, it can also contribute to saving cement, reducing the cost of concrete, reducing CO2 emissions, and achieving the dual-carbon goal as soon as possible for the sustainable development of society.
[0003] The relationship between the dosage and performance of the concrete synergist is very close, and it is necessary to strictly control the addition amount of the concrete synergist according to the amount of cement to achieve the expected effect. This requires that when preparing concrete, a suitable method should be adopted to add the synergist to the concrete to avoid problems such as excessive errors caused by unreasonable operations such as scooping or pouring.
