Description
Technical field
The invention belongs to the realm of building construction, are related to a kind of concrete, and in particular to a kind of high-tensile concrete and
Preparation method.
Background technique
Concrete has many advantages, such as that intensity is high, durability is good and plasticity is strong, is that modern construction engineering is most widely used
Material.But existing concrete haves the shortcomings that tensile strength is low, is easy to produce crack under the influence of temperature, humidity variation.Mesh
The method of premise high concrete tensile strength mainly divides physical method and chemical method.Wherein physical method includes: improving cement
Intensity improves aggregate quality, coarse aggregate surface and reinforces early curing.But above-mentioned front two is used in construction at the scene
When kind method enhancing concrete tensile strength, economic cost will increase；Two methods enhance concrete tensile strength behind use
When, it will increase time cost and labour cost.
In the existing patent for improving concrete tensile strength using chemical method, the chemical substances such as resin is mostly used to enhance sand
The intensity of slurry, and then improve the tensile strength of concrete.The method increases mixed compared with consistency of mortar is improved for physical method
Solidifying soil mobility, enhances strength of cement, further improves concrete tensile strength.But concrete is carefully seen studies have shown that boundary
Face (aggregate is with the interface between mortar) has lower intensity compared with aggregate, mortar, therefore interface is control agent on crack resistance of concrete
The determinant of tensile strength, so the method for being improved concrete tensile strength using chemical substance reinforced mortar intensity will cause
The chemical substances dosage such as resin is higher, wastes, and increases cost.
Summary of the invention
In view of deficiency existing for concrete tensile strength method is improved in the prior art, the purpose of the present invention is to provide one
The method of kind enhancing concrete tensile strength, quasi- to overcome deficiency in the prior art: (1) economy, time, labor cost are high；
(2) amount of resin wastes.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of high-tensile preparation method of concrete, it is characterised in that: aggregate is first cohered into glue with chemistry and is mixed, is mixed
The concrete slurry of high-tensile is mixed together to form with the cement mortar mixture prepared afterwards, concrete slurry casting is solid
It is the concrete structure of high-tensile after change, the chemistry, which coheres glue and formed to have between aggregate and mortar, increases by two
The bonding interface of person's bond strength.
Preferably, it includes epoxy resin and curing agent that the chemistry, which coheres glue,.
Preferably, the epoxy resin is bisphenol-type epoxy resin.
Preferably, the curing agent is in polyhydric aliphatic amine, Versamid, polysulfide and amido amine
Any one is several.
A kind of high-tensile concrete, including aggregate and mortar, it is characterised in that: the aggregate surface, which is attached with, to be used for
The chemistry for increasing aggregate and mortar interface bond strength coheres glue, and chemistry coheres glue and forms bonding circle between aggregate and mortar
Face.
Beneficial effects of the present invention:
(1) for the present invention compares conventional physical method, the required raw material sources of this present invention are easy to get extensively, can save
Economic cost, and do not need later period investment manpower and material resources and carry out reinforcement maintenance；
(2) for the present invention compares existing chemical method, amount of resin needed for this method is less, more economically；
(3) effect of concrete tensile strength is improved compared with prior art in the interface most weak present invention enhances concrete
For it is more significant.
Detailed description of the invention
Fig. 1 is high-tensile concrete structure schematic diagram of the present invention.
Fig. 2 is high-tensile concrete preparation flow figure of the present invention.
Appended drawing reference: 1- chemistry coheres glue, 2- aggregate, 3- mortar, 4- bonding interface.
Specific embodiment
The present invention is illustrated with reference to the accompanying drawing.
As shown in Figure 1, a kind of high-tensile concrete, including aggregate 2 and mortar 3,2 surface of the aggregate attachment are useful
Glue 1 is cohered in the chemistry for increasing aggregate 2 and 3 water ratio limit intensity of mortar, chemistry coheres glue 1 and formed between aggregate 2 and mortar 3
Bonding interface 4, which greatly enhances the bond strength between aggregate 2 and mortar 3, to improve concrete
Whole tensile property.
The high-tensile preparation method of concrete takes 75% aggregate 2 and 2% as shown in Fig. 2, calculate according to total amount
Chemistry coheres glue 1 and is uniformly mixed, so that chemistry coheres glue 1 and is attached on aggregate 2, while taking 17% cement and 6% water mixed
Then conjunction form mortar 3 will be attached with chemistry and cohere the aggregate 2 of glue 1 and mortar 3 mixes, stirring of vibrating is poured
It infuses, in solidification process, chemistry coheres glue 1 and forms bonding interface 4 between aggregate 2 and mortar 3, after conserving 28 days, can be obtained
High-tensile concrete structure.The concrete structure being poured using present invention process, tensile strength are significantly promoted, most
Height can promote 50% or so.
It is particularly suitable for needing the occasion of tensile strength, such as crossbeam using concrete structure prepared by the present invention, hang
Outrigger etc..
It may be noted that the embodiment of the present invention in said components the restriction not represented to protection scope, the ratio of each component
It can be adjusted according to the actual situation.
