Description

Integrated production line for field mixing and construction for preparing green high-performance concrete

Technical Field

The utility model relates to a field of preparation green high performance concrete is mixed and construction integration production line belongs to concrete preparation technical field.

Background

The concrete is the largest building engineering material and structural engineering material for various human engineering constructions, and the existing concrete has the problems of poor durability, serious structural cracking, insufficient strength and the like.

The existing building concrete member commonly has the conditions of 'fat beam, fat column and thick pier', which wastes resources greatly; the building concrete structure cracks seriously, and the building quality safety is seriously influenced by the ground step of 'no room, no bridge and no dam' and the like; in the existing premixing concrete pumping process, in order to solve the workability problem of concrete for 2 hours, various additives are greatly added, so that recessive defects and hazards are brought to the long-term quality stability of a building, and the sustainable development of the concrete is seriously restricted.

In conclusion, the current concrete production pumping process cannot meet the requirement on concrete durability, cannot meet the concepts of high-quality development and green low-carbon environmental protection development of the building industry, and cannot meet the design requirement of 'one-hundred-year engineering and thousands of years' under the basic goal of national high-quality development, so that the technical innovation is urgently waited, a novel concrete manufacturing and construction technology with more advanced and more green process, higher concrete strength and longer service life is developed, and the fifth technical revolution of the concrete industry is promoted.

Analysis of the cause of the existing problems of concrete:

(1) A construction process for pumping premixed concrete,

is influenced by environmental protection policy, and improves the requirements of concrete performance and concrete dosage. The traditional on-site simple stirring scheme is eliminated by the construction technology of premixed concrete pumping. The ready-mixed concrete mixing plant solves the problems of environmental protection and metering precision of the traditional on-site simple mixing, and becomes the main construction process of the existing concrete. However, the ready-mixed concrete mixing plant is usually built in a remote suburb, the urban building is located in the urban center, and after the production of the concrete is completed through the mixing plant in the suburb, the concrete is transported to a building construction site within 2 hours through the concrete mixing truck and is pumped to a high-rise building through the concrete pump truck. Just because of these two-hour transport distances, new problems are brought to modern concrete quality:

1) The durability of the concrete is reduced. In order to ensure that the concrete mixer truck is transported to a construction site within 2 hours, the concrete still has good workability, a production enterprise greatly adds additives into the concrete to prolong the setting time of the concrete, hidden defects and hazards are brought to the long-term quality stability of a building, the service life of the concrete is sacrificed, and the production cost of the concrete is increased;

2) The transportation cost of the concrete increases. The back and forth transportation cost of the concrete mixer truck is high, the mixer truck needs to be cleaned every time of transportation, water resources are consumed greatly, the mixer truck almost has 5% of unclean loss during the operation of concrete every time, huge waste is brought in a large casting site, and new pollution caused by new energy consumption is brought.

(2) The concrete is not mixed uniformly, the strength and the service life are influenced,

the main raw materials of the concrete are prepared by mixing sandstone aggregate, various powders, water and various additives, and the traditional process is realized by prolonging the mixing time of the concrete along with the improvement of the strength or the grade of the concrete, so that the uniformity of each component of the concrete is improved. Traditional stirring host computer is mostly mechanical stirring, and low-speed through mechanical blade rotates, makes to produce convection current, vortex, shearing action between the material, realizes the intensive mixing of material. The powder for concrete is fine, the particle size of the ultrafine powder even reaches the nanometer level, a mechanical stirring device, gravel aggregate and the powder have a gap in size, the problem of mixing of the powder cannot be fundamentally solved, and microscopically, the powder still has local single components and cannot be subjected to sufficient chemical reaction, so that the concrete has hidden cracks and the strength of the concrete cannot be fully exerted. And the unevenness of components brings the nonuniformity of the strength of the concrete member, and the nonuniformity needs to be ensured by improving the strength coefficient of the concrete, thereby causing the occurrence of the conditions of 'fat beams, fat columns and thick piers' and wasting a large amount of non-renewable resources.

(3) The instability of the aggregate gradation of the sandstone,

the machine-made sandstone aggregate is the main component of concrete, accounts for more than 75-85% of the concrete, and the quality of the aggregate plays a decisive role in the quality of the concrete. The sandstone aggregate coarse and fine materials have large particle size difference, and the particle size is from millimeter to micron. Segregation phenomenon is inevitable in the process of storing and transporting the sandstone aggregate. This makes the gradation of each batch of mechanism grit aggregate all different, also leads to concrete mixing's concrete production raw materials each batch different, lets the accurate measurement of mixing plant can't realize the accurate control of concrete raw materials.

(4) The disjunction of the sandstone aggregate production and the concrete raw product material flow management,

the material flow management of the sand production and the concrete production cannot be unified, and the quality of the concrete raw materials is bound to a certain degree. Sandstone production enterprises pay attention to the production quality control of sandstone, and concrete mixing plants pay attention to the metering. The storage, transportation and transportation in the middle lack the necessary quality control. This is also one of the causes of deterioration in the quality of concrete.

With the continuous development of society, the market has higher and higher requirements on the quality of concrete, so that the research on a field mixing and construction integrated production line for preparing green high-performance concrete is an urgent technical problem to be solved.
