Description
Technical field
The invention discloses a kind of clear-water concrete, belong to building material technical field.
Background technology
Clear-water concrete refers to pour surface or with concrete original with the transparency protected dose of concrete table for doing protectiveness processing
Effect attractive in appearance is realized by the true qualities of concrete and itself texture and the presentation quality of well-designed construction as outer surface in face
The cast-in-place concrete of fruit.One-time-concreting, it is not added with 2 points that any plug-in finishing is clear-water concrete most critical.In recent years,
Clear-water concrete is more and more to be applied in Industrial and Civil Engineering, and its main feature has following：1. lift engineering
Quality.Clear-water concrete does not do any modification, and quality integrates " essence, thin, U.S. ", and the requirement of its work progress has sternly per procedure
Lattice are divided the work and special messenger is responsible for, and to be increased on-site supervision dynamics in construction and be carried out power, accomplish to design and construct not separating,
Expected Results is only in this way just can guarantee that, so as to General Promotion construction quality.Meanwhile promote clear-water concrete and be advantageous to lift me
The concrete technology aggregate level of state；2. save project total cost.The impression quality of clear-water concrete is unornamented, eliminates
Coat of plaster and surface layer.Therefore finishing fund has been saved, has reduced engineering cost；3. reduce engineering maintenance expense.Clear-water concrete,
Eliminate and plaster, avoid the generation of general concrete Structural Engineering hollowing, crack, come off this kind of mass defect, it is often more important that
Reduce maintenance load, difficulty and expense；4. obvious environment benefit.The importance of society's increasingly Considering Environmental now, clearly
Water coagulation soil one-shot forming, it is not necessary to repairing is plastered, and is so considerably reduced building waste, is real Green environmental-protection building,
It is highly beneficial to environmental protection.
The maximum difference of clear-water concrete and normal concrete is that clear-water concrete does not have the dress on normal concrete surface
Exterior material protective layer and be exposed to for a long time in external environment, directly by the corrosiveness of external environment, cracking phenomena can be produced,
This durability to clear-water concrete just proposes more strict requirements.So-called clear-water concrete outward appearance durability refers to clear water
Concrete structural surface is in design service life, and resistance is extraneous or erosion damage acts on caused by itself, keeps its original
The ability that performance and outward appearance are not destroyed.The outward appearance durability damage and normal concrete durability damage one of clear-water concrete
Sample, it is the result of many factors comprehensive function.And among these, the anti-permeability performance and anti-carbonation properties of clear-water concrete seem
It is particularly important.
Therefore, a kind of clear-water concrete for having excellent crack resistance, anti-permeability performance and anti-carbonation properties concurrently, Cai Nengkuo are prepared
The use range of big clear-water concrete.
The content of the invention
The present invention solves the technical problem of：Occur coagulating soil and being affected by the external environment to produce resisting for traditional clear water is mixed
A kind of the problem of splitting poor performance, anti-permeability performance and bad anti-carbonation properties, there is provided clear-water concrete.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of clear-water concrete, it is made up of the raw material of following parts by weight：90~100 parts of river sands, 30~40 parts of silicate cements
