Description

A kind of very-high performance architectural concrete and preparation method thereof
Technical field
The present invention relates to a kind of green construction materials and preparation method thereof, and in particular to it is a kind of with decorating structure one Very-high performance architectural concrete.
Background technology
The double action that concrete structure possesses aesthetic value with space expressive force, traditionally, concrete is led under construction Structural material is used for, load-bearing to be its most important function.With the development of green building theory, there is the coagulation of decoration functions Soil becomes the hot spot of Recent study.
Clear-water concrete belongs to a branch of architectural concrete, it belongs to one-time-concreting molding, does not do any external decoration, Directly using the surface of cast-in-place concrete as facing, it is very natural that surfacing is smooth, uniform color, entirety seem, solemnly. However all seem that comparison is heavy as load-carrying members, it makes more difficult during labyrinth, aesthetic requirement can not be met, be not achieved The purpose of structure and decorating integrative.
Ultra-high performance concrete(UHPC)Composition material include different-grain diameter particle with optimal proportion formed most compact reactor Product, using relatively low water-cement ratio and high efficiency water reducing agent, UHPC has excellent mechanical property, larger mobility, preferable resistance to The performances such as long property, are conducive to construct, and the UHPC mechanical properties of appropriate arrangement of reinforcement are close to steel construction.However UHPC substantially gray, Dark grey, apparent colour is more gloomy, and the more stomatas in surface, rougher, can not meet the aesthetic effect of decoration.
Invention content
In view of the deficiencies of the prior art, the present invention is prepared for a kind of very-high performance architectural concrete, can be fabricated to originally Grey, simple and elegant white can also be fabricated to using white cement, pigment can also be added and be fabricated to colour.Bubble in mortar It reduces, so as to make finished surface smooth not coarse.In addition, by adjusting proportioning, good mortar mobility is realized, so as to pour It builds in complicated die, complicated shape is made.To sum up, the product of this patent can have outstanding decoration performance.

Further, it is micron-sized silicon ash, slag, flyash, kaolin, zeolite powder that the industrial residue, which is grain size, One or more of with mine tailing.
Further, the nano particle is particle enhancing and the particle of filling effect, selected from Nano-meter SiO_22, carbon nanometer Pipe, nanometer Al2O3And Nano-meter CaCO33One or more of.
Further, the high-performance water reducing agent is not less than 35% water-reducing agent for water-reducing rate.
Further, the antifoaming agent is one or both of silicone fluid, dimethyl silicone polymer.
Further, the fine aggregate is yellow ground of the grain size less than 2.5mm or quartz sand or tailings and its mixture.
A kind of very-high performance architectural concrete, including following preparation process:
(a)Portland cement, industrial residue, pigment, fine aggregate weigh to be put into stirrer for mixing uniform in proportion;
(b)Will dissolved with the mixed solution of water-reducing agent, antifoaming agent and water add in blender in, stir 3-5min, make solid material from Dispersity becomes viscous paste state;
(c)High-intensity fiber is evenly spread in slurry, continues to stir 3-5min, obtains very-high performance architectural concrete;
(d)Obtained very-high performance architectural concrete is poured in a mold, then the upper plastic film of surface covering, supported naturally 28d ages are arrived in maintenance under the conditions of shield.
Compared with prior art, beneficial effects of the present invention are as follows:
(1)Raw materials derive from a wealth of sources, and largely using industrial residue, are conducive to ecological ideas sustainable development;
(2)The very-high performance architectural concrete of the present invention has self compacting ability, avoids vibration, reduces process complexity, greatly It is big to improve economy;
(3)After mixing fiber, prepared ultra-high performance concrete has preferable toughness and crack resistance, therefore can be with Mold the decoration element of labyrinth.By adding in pigment in the present invention, the very-high performance prepared herein can be made Architectural concrete had not only had preferable mechanical property but also had had both decoration performance, had reached structure and the dual purpose of decoration.Make it Surface has decorative lines, pattern, texture, texture and color.
