Description
Technical Field
The invention relates to the technical field of concrete quantitative proportioning, in particular to a mixing device and a mixing method for concrete quantitative proportioning.
Background
Concrete is a general term for engineering composite materials in which aggregate is cemented into a whole by a cementing material. The concrete is cement concrete, also called common concrete, which is prepared by mixing cement as cementing material, sand and stone as aggregate, and water (optionally containing additive and admixture) in a certain proportion and stirring.
Concrete is one of the most important civil engineering materials of the present generation. The artificial stone is prepared by a cementing material, granular aggregate (also called aggregate), water, an additive and an admixture which are added if necessary according to a certain proportion, and is formed by uniformly stirring, compacting, forming, curing and hardening. The concrete has the characteristics of rich raw materials, low price and simple production process, so that the consumption of the concrete is increased more and more. Meanwhile, the concrete also has the characteristics of high compressive strength, good durability, wide strength grade range and the like. These characteristics make it very widely used, not only in various civil engineering, that is shipbuilding, machinery industry, ocean development, geothermal engineering, etc., but also concrete is an important material.
The concrete has the following properties:
workability: the most important properties of concrete mixtures. It comprehensively expresses the consistency, the fluidity, the plasticity, the anti-demixing and segregation bleeding performance, the easy-to-smear property and the like of the mixture. Methods and indexes for measuring and expressing the workability of the mixture are many, and China mainly adopts slump (millimeter) measured by a truncated cone slump cone and the Weibo time (second) measured by a Weibo instrument as main indexes of the consistency.
Strength: the most important mechanical properties of the hardened concrete refer to the ability of the concrete to resist stresses such as compression, tension, bending and shearing. The water cement ratio, the variety and the dosage of cement, the variety and the dosage of aggregate, stirring, forming and curing all directly influence the strength of concrete. The improvement of the ratio of tensile strength to compressive strength of concrete is an important aspect of concrete modification.
Deformation: the concrete can deform under the action of load or temperature and humidity, and mainly comprises elastic deformation, plastic deformation, shrinkage, temperature deformation and the like. The elastic deformation of concrete under short-term loading is mainly expressed by the modulus of elasticity. Under the action of long-term load, the stress is unchanged, the phenomenon that the strain is continuously increased is creep, the phenomenon that the strain is unchanged, and the phenomenon that the stress is continuously reduced is relaxation. The volume deformation due to hydration of cement, carbonization and water loss of set cement is called shrinkage.
The concrete needs to make up the material among them and carry out the ration to mix in production and processing in-process, and current compounding equipment is when carrying out the ration compounding, usually prepares the material that waits to mix in advance to prepare according to certain weight ratio or volume ratio, then puts into the compounding equipment with the material, fully mixes the material through the compounding structure, but the compounding equipment itself does not have the function of ration, need carry out the ration with the help of extra equipment or instrument.
