Abstract
The invention discloses a formula of high-strength composite reinforced concrete. The locally-prepared CFRP-PCPs composite reinforced concrete comprises the components in parts by weight: 4 parts of high-performance active powder, 20 parts of CFRP-PCPs reinforcements, 48 parts of cement, 30 parts of coarse sand, 30 parts of gravels and 45 parts of water. According to the formula of the high-strength composite reinforced concrete, disclosed by the invention, the defects such as unreasonable ratio, low reliability, poor rigidity and the like in the prior art can be overcome, so that the advantages of reasonable ratio, high reliability and good rigidity can be achieved.
Description
Technical field
The present invention relates to concrete processing technique field, particularly, relate to a kind of formula of high-strength composite reinforced concrete.
Background technology
In recent years, along with carbon fiber (Carbon Fiber Reinforced Polymer, the CFRP) design theory of muscle material and the maturation of operating technique, become the ideal substitute of reinforcing bar gradually, and apply in Practical Project.But itself be the material of high strength low elastic modulus, the shortcoming such as on-the-spot stretch-draw prestressing force operational difficulty in its resistance to shear difference and construction, in building structure, its performance can not give full play to.But CFRP muscle is heavily processed, improves its force way.Adopt CFRP-PCPs (Carbon Fiber Reinforced Polymer Prestressed Concrete Prisms) composite reinforcing to replace traditional CFRP muscle herein, CFRP-PCPs composite reinforcing had both maintained the advantages such as the tensile strength of CFRP muscle is high, corrosion-resistant and had which in turn improved the shortcoming such as shear behavior difference, high strength low-elasticity-modulus.
Realizing in process of the present invention, contriver finds at least to exist in prior art that proportioning is unreasonable, reliability is low and the defect such as poor rigidity.
Summary of the invention
The object of the invention is to, for the problems referred to above, propose a kind of formula of high-strength composite reinforced concrete, to realize the advantage of the high and good rigidly of reasonable ratio, reliability.
For achieving the above object, the technical solution used in the present invention is: a kind of formula of high-strength composite reinforced concrete, and this local is joined each component and parts by weight thereof in CFRP-PCPs composite rebar concrete and is:
High-performance reactive powder: 4 parts;
CFRP-PCPs muscle: 20 parts;
Cement: 48 parts;
Coarse sand: 30 parts;
Cobble: 30 parts;
Water: 45 parts.
The formula of the high-strength composite reinforced concrete of various embodiments of the present invention, joining each component and parts by weight thereof in CFRP-PCPs composite rebar concrete due to this local is: high-performance reactive powder: 4 parts; CFRP-PCPs muscle: 20 parts; Cement: 48 parts; Coarse sand: 30 parts; Cobble: 30 parts; Water: 45 parts; Thus can overcome in prior art that proportioning is unreasonable, reliability is low and the defect of poor rigidity, to realize the advantage of the high and good rigidly of reasonable ratio, reliability.
Other features and advantages of the present invention will be set forth in the following description, and, partly become apparent from specification sheets, or understand by implementing the present invention.
Below by embodiment, technical scheme of the present invention is described in further detail.
Embodiment
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
According to the embodiment of the present invention, provide a kind of formula of high-strength composite reinforced concrete, this local is joined each component and parts by weight thereof in CFRP-PCPs composite rebar concrete and is:
High-performance reactive powder: 4 parts;
CFRP-PCPs muscle: 20 parts;
Cement: 48 parts;
Coarse sand: 30 parts;
Cobble: 30 parts;
Water: 45 parts.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
