Abstract
The invention discloses a concrete formula. The concrete formula is characterized by comprising 50 to 60 parts of a mixture, 10 to 18 parts of yellow sand, 5 to 7 parts of powdered carbon, 1 to 4 parts of calcium carbonate, 8 to 10 parts of an adhesive, 100 to 110 parts of cement, 70 to 80 parts of water, 8 to 12 parts of quicklime, 0.1 to 0.2 part of zinc sulfate, 5 to 8 parts of an air-entraining agent, 1.5 to 3 parts of macroporous resin and 0.5 to 1 part of a water reducing agent. Concrete prepared according to the concrete formula has low production cost and overall high performance.
Description
Technical field
The present invention relates to a kind of concrete formulation.
Background technology
The pore porous body that concrete is made up of cement mortar and coarse aggregate. When mixing concrete in order to obtain the workability of necessity, the mixing water of addition is always more than the water of hydration of cement. The unnecessary aquiform stool of this part is stranded in concrete with the form of free water to be formed the pore of connection, and occupies certain volume. Architectural engineering for northern China cold district, concrete in hydraulic engineering, 1) when concrete is in water-saturated state: water meets cold junction ice, and volumetric expansion can occur, and when expanding the pressure produced more than concrete tensile strength, can cause the destruction of concrete inner structure. Under freeze-thaw cycle effect repeatedly, the reduction of concrete peeling and intensity can be caused. 2), when concrete is in water-saturated state: the non-capillary hole that the gel pore formed after some hydrated cementitious except pore in concrete and other reasons are formed, these spaces are often mixed with air. Therefore, when the water freezing in pore expands, these pores can play dash adjustment effect, the water that a part does not freeze can be clamp-oned gel pore and non-capillary hole, thus reducing the bulbs of pressure; But under the effect of freeze-thaw cycle, the water clamp-oning gel pore and non-capillary hole can get more and more, until being in saturation, finally causes the reduction of concrete peeling and intensity.
At present, the concrete major part used in the civil engineering of cold district, hydraulic engineering is normal concrete, after standing the freeze-thaw cycle effect of less than 100 times, namely intensity be greatly lowered, loss of strength is too fast, and under freeze-thaw cycle effect, concrete outer layer easily peels off, separates.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of concrete formulation, and the concrete production cost that this concrete formulation prepares is low, and the concrete various aspects of performance obtained is all higher.
For achieving the above object, the invention provides a kind of concrete formulation, it is characterized in that, comprise the steps, compound 50-60 part, yellow sand 10-18 part, carbon dust 5-7 part, calcium carbonate 1-4 part, adhesive 8-10 part, cement 100-110 part, water 70-80 part, quick lime 8-12 part, zinc sulfate 0.1-0.2 part, air entraining agent 5-8 part, macroporous resin 1.5-3 part, water reducer 0.5-1 part.
The invention has the beneficial effects as follows: the technical problem to be solved is to provide a kind of concrete formulation, and the concrete production cost that this concrete formulation prepares is low, and the concrete various aspects of performance obtained is all higher.
Detailed description of the invention
Technical scheme disclosed by the invention is a kind of concrete formulation, comprise the steps, compound 55 parts, yellow sand 13 parts, carbon dust 6 parts, calcium carbonate 3 parts, adhesive 9 parts, cement 105 parts, 78 parts of water, quick lime 10 parts, 0.2 part of zinc sulfate, air entraining agent 6 parts, macroporous resin 3 parts, water reducer 1 part.
The technical problem to be solved is to provide a kind of concrete formulation, and the concrete production cost that this concrete formulation prepares is low, and the concrete various aspects of performance obtained is all higher.
The preferred embodiment of the present invention described in detail above. Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work. Therefore, all technical staff in the art, all should in the protection domain being defined in the patent claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
