Abstract
The invention discloses a new formula of composite reinforced concrete. The composite reinforced concrete which is partially provided with CFRP-PCPs comprises the following components in parts by weight: 4 parts of high-performance active powder, 29 parts of CFRP-PCPs ribs, 56 parts of cement, 32 parts of coarse sand, 29 parts of gravels and 54 parts of water. The new formula of the composite reinforced concrete, disclosed by the invention can be used for overcoming the defects of unreasonable proportion, low reliability, poor rigidity and the like in the prior part, thereby achieving the advantages of reasonable proportion, high reliability and good rigidity.
Description
Technical field
The present invention relates to concrete processing technique field, particularly, relate to a kind of new formula of composite rebar 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 new formula of composite rebar 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 new formula of composite rebar 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: 29 parts;
Cement: 56 parts;
Coarse sand: 32 parts;
Cobble: 29 parts;
Water: 54 parts.
The new formula of the composite rebar 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: 29 parts; Cement: 56 parts; Coarse sand: 32 parts; Cobble: 29 parts; Water: 54 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 new formula of composite rebar 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: 29 parts;
Cement: 56 parts;
Coarse sand: 32 parts;
Cobble: 29 parts;
Water: 54 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.
