Description

A kind of concrete for the preparation of electric power electric pole

Technical field

The invention belongs to concrete technology field, more specifically, relate to a kind of concrete for the preparation of electric power electric pole.

Background technology

Concrete refers to the general designation that is cemented to overall engineered composite material by gelling material by gathering materials.Conventionally concrete one word of saying refers to cement makes gelling material, and sand, masonry gather materials; Coordinate by a certain percentage with water (can contain admixture and adulterant), through stirring and cement concrete, also claim normal concrete, it is widely used in civil engineering work.Concrete refers to the compound by agglutinate (organic, inorganic or organic-inorganic compound), particulate state are gathered materials, water and the chemical admixture that need to add and mineral admixture form by suitable proportion mixing, or formation has the matrix material (common is with gelling material, water, fine aggregate, coarse aggregate) of piling poly structure after sclerosis, while needs, mix admixture and mineral admixture, coordinate by suitable proportion.Concrete has abundant raw material, cheap, the simple feature of production technique, thereby make its consumption increasing.It is high that while concrete also has ultimate compression strength, good endurance, the features such as strength grade wide ranges.These features make its use range very extensive, not only in various civil engineering works, use, and be exactly shipbuilding, mechanical industry, the exploitation of ocean, geothermal engineering etc., concrete is also important material.

Concrete is a kind of material of construction full of vitality.Along with the development of component materials of concrete, people improve constantly Material cladding technology understanding.Concrete performance requriements is not only confined to ultimate compression strength, but on the basis of basing oneself upon intensity, more focuses on the balance and coordination of the overall targets such as concrete weather resistance, deformation performance.The requirement of concrete property indices is than clearer and more definite, refinement and concrete in the past.Meanwhile, the lifting of Architectural Equipment level, continuing to bring out and promoting of novel construction process, makes concrete technology adapt to different designs, construction and service requirements, develops very fast.

Concrete has wide range of applications, and also has use in transmission system.Current common prestressed concrete electric pole can only be used for the power transmission sequence below 220kV, widespread use steel tower in ultra-high voltage power transmission sequence.Owing to being metal construction, easily there is corrosion in this class tower structure, therefore work-ing life shorter, maintenance workload is large.And traditional normal concrete electric pole physical strength is not high, be difficult to be applied in high voltage circuit, unless cross section is done larger, but so both increased deadweight, make construction become very difficult, prior again increase cost.How to develop a kind of physical strength large, weight electric power electric pole concrete material less and with low cost is prior art technical problem urgently to be resolved hurrily.

Summary of the invention

The object of the invention is to solve in prior art concrete many defects for electric power electric pole, through lot of experiments and exploration, change raw material composition and the preparation technology of existing concrete, a kind of electric power electric pole concrete is provided, it is large that this concrete possesses physical strength, the advantage such as less, the with low cost and preparation method of weight is simple.

To achieve these goals, technical scheme of the present invention realizes in the following way:

For the preparation of a concrete for electric power electric pole, it is prepared as follows and forms:

Step 1) is prepared material A: slag and carbide slag are mixed, then put into pulverizer and be ground into particle, keep the particle diameter of particle below 1cm, then add barium sulfate, mix, finally deliver to ball mill, be milled to the powder that particle diameter is 100um, be material A; Wherein, the weight ratio of slag, carbide slag and barium sulfate is 200:100:1;

Step 2) prepare material B: kaolin and diatomite are mixed according to the weight ratio of 1:1, then add 5%(V/V) hydrochloric acid, soak 10min, centrifugal 3 minutes of 500 turn/min, collecting precipitation, obtains material B;

Step 3) is prepared material C: quartz sand, humic acids and water are mixed, stir 3 minutes with the stirring velocity of 500 turn/min, obtain material C; Wherein, the weight ratio of quartz sand, humic acids and water is 3-5:1-2:10-15;

Step 4) is prepared concrete: toward add materials successively in stirrer A, material B, material C and ordinary Portland cement, be stirred to evenly, leave standstill 30 minutes, be then expelled in container, obtain concrete; Wherein, material A, material B, material C and ordinary Portland cement are 3-4:3-4:5-6:7-9.

Preferably, slag is the mixture of blast-furnace slag, Copper Slag or the two arbitrary proportion;

Preferably, the particle diameter of quartz sand or humic acids is all controlled at 100um-200um;

Preferably, ordinary Portland cement is No. 42.5 ordinary Portland cements.

The beneficial effect that the present invention obtains mainly comprises:

In concrete formulation of the present invention, adopt a large amount of cheap raw material and industrial waste, greatly reduced the cost of product, realized and having turned waste into wealth;

Concrete of the present invention, through lot of experiments and exploration, changes raw material composition and the preparation technology of existing concrete, part material is carried out to modification simultaneously, and its concrete of preparing possesses that physical strength is large, weight is less and the advantage such as corrodibility is little;

Concrete use range of the present invention is extensive, can make common electric pole, is applicable to low pressure rural area electrical network, is also suitable for high-voltage fence;

Concrete material preparation method simple possible of the present invention, is applicable to suitability for industrialized production.
