Abstract
The invention discloses a method for preparing a high-strength concrete, comprising the following raw materials of cement with the weight of 475-485kg/m<3>, sands with the weight of 585-615kg/m<3>, gravels with the weight of 1030-1050kg/m<3>, water with the weight of 148-152kg/m<3>, water reducing agent with the density of 9.45-9.75kg/m<3> and composite fine powders with the weight of 118-122kg/m<3>, and the method comprises the following steps of: firstly mixing the sands and the gravels in a blender mixing vat, subsequently adding the cement and the composite fine powders in the blender mixing vat, starting a water valve and a water reducing agent valve simultaneously, leading the water and the water reducing agent to be sprayed in the mixture, and mixing uniformly. Taking the conventional cement, sands and gravels as the raw materials and being added with the water reducing agent and a certain amount of active mineral admixture, the newly mixed concrete has excellent workability and forms the cement concrete with high strength and high compactness performance after hardening, thus reducing production cost and being capable of being widely applied to the national constructional engineering construction. According to the test, the high-strength concrete prepared by the method has the strength of 72.9MPa after 7 days and has the strength of 90.8MPa after 28 days.
Description
Technical field
The present invention relates to the higher concrete of a kind of ultimate compression strength, especially relate to a kind of compound method of high-strength concrete.
Background technology
Along with progress of science and technology and development, modern architecture constantly to high-rise, stride greatly, underground, ocean direction develops.High-strength concrete (routine refers to the concrete of C60 and above grade) is owing to having good endurance, intensity height, being out of shape advantages such as little, can adapt to the modern project structure to stride greatly, heavy duty, towering development and bear the needs of severe environmental conditions, can also reduce simultaneously member section, increase usable floor area, reduce construction costs, therefore obtain application more and more widely, and obtained tangible technical economic benefit.
The modern concrete Developing Trend in Technology, it is the fluidization of concrete high reinforcement and high-strength concrete, develop rapidly along with construction industry, improve the concrete intensity of engineering structure, become the problem that various countries, world today civil construction project circle is generally paid attention to, it is one of main direction of concrete technology development, also is one of important technique measure of saving the energy, resource.Adopt special material (as fiber) to strengthen or special warfare (as high-pressure steaming and cultivating), can make high-strength concrete or super high strength concrete with comparalive ease.But because various reasons such as cost height, the high-strength concrete of special material or special warfare is difficult to apply in China.Because concrete intensity is mainly from the granule strength of grout intensity, grout and aggregate interface cohesive strength, aggregate, therefore, how to use common material and common process to make strong concrete, in China's Structural Engineering, applied, be significant.
Summary of the invention
The object of the present invention is to provide a kind of compound method that adopts the high-strength concrete of common material and the realization of conventional construction technology.
For achieving the above object, the present invention can take following technical proposals:
The compound method of high-strength concrete of the present invention, it is to be formed by following preparation of raw material:
The weight part proportioning:
Cement 475-485Kg/m
3, sand 585-615Kg/m

Blending means:
Elder generation puts into stirrer mixing in-drum mixing with sand, rubble, and then adds cement and composite fine powders, opens water valve and water reducer valve simultaneously, and water and water reducer evenly are sprayed in the mixed material, mixes to get final product.
The weight part proportioning of described raw material is: cement 475Kg/m
3, sand 615Kg/m
3, rubble 1030Kg/m
3, water 148Kg/m
3, water reducer 9.75Kg/m
3, composite fine powders 122Kg/m
3
The weight part proportioning of described raw material also can be: cement 480Kg/m
3, sand 600Kg/m
3, rubble 1040Kg/m
3, water 150Kg/m
3, water reducer 9.6Kg/m
3, composite fine powders 120Kg/m
3
The weight part proportioning of described raw material also can be: cement 485Kg/m
3, sand 585Kg/m
3, rubble 1050Kg/m
3, water 152Kg/m
3, water reducer 9.45Kg/m
3, composite fine powders 118Kg/m
3
The fineness 2.8 of described cement, consumptive use of water normal consistence 26.5%.
The silt content 1.6% of described sand contains clod amount 0.5%, two district's grain composition, fineness modulus 2.8.
The content of stone powder 1.5% of described rubble, faller gill shape content 4%, crush index 4.1%.
Described water reducer is the polyocarboxy acid type water reducer, water-reducing rate 30%, solid content 26%.
Described composite fine powders is made up of flyash 60%, ground slag 30%, silica flour 10%.
The invention has the advantages that and use conventional cement, sand, rubble to be starting material, rely on the active mineral admixture that adds water reducer and some amount, make freshly mixed concrete have good operation, and after sclerosis, form cement concrete with the real performance of high-strength high-density.Its advantage mainly shows as:
1, intensity height.The raising of ultimate compression strength can make reinforced column and arch shell etc. increase substantially based on the sand power of carrying of the member that is stressed, can make the cross section minimizing of member under identical load; In flexure member, can reduce the pressure zone concrete height in cross section, therefore, utilize the high characteristic of its strength of materials, can reduce the member section size significantly, reduce the member body weight, increase the building useful space and span, and in some fields the instead of steel structure.
2, mobile big, the early strength height.High-strength concrete with the present invention's preparation can have the big and early strong performance of the slump simultaneously, can adopt mechanized construction technologies such as commerical ready-mixed concrete and pumping, and the turnover of template is quickened in form removal in early days in the construction, shortens construction period, and speed of application is provided.
3, good endurance.High-strength concrete by higher density, so anti-outside erosional competency is strong, has favorable durability than general concrete.
4, in light weight, the material-saving effect is remarkable.The sectional dimension that reduces structure means the reduction dead load, increases effective usable floor area.In the ordinary course of things, strength grade of concrete is brought up to C60 by C30, and structural volume can reduce 1/3, and corresponding body weight also can reduce 1/3, often can also make fast hard, the weather resistance improvement of concrete, and the work-ing life of buildings will be above a century.Can reduce material usage and building cost in a large number in addition, production, transportation and construction energy consumption also will significantly reduce.
The prepared high-strength concrete of the present invention is through test, and intensity can reach 72.9MPa in 7 days, and intensity can reach 90.8MPa in 28 days.
